DARPA Discussion Forum Closed

John Wiseman — Thu, 20 Dec 2007 16:14:00 PST

It looks like DARPA deactivated the Grand Challenge discussion forum a while back, hence the lack of new posts in the feed. I'll keep the feed URL going for a bit, but it too will eventually disappear.

Until next time,

I saw some of that on the 2004 forum which was closed when the 2005 event kicked off. Nothing ever happened with it, probably due to the lack of funds. The 2004 forum might still be around in an archive.

There was also an attempt to do Pikes Peak, the Axion team actually did the entire 14 mile course in a demo run. That race was postponed for a year then abandoned.

previous challenges.

So why exactly arent we doing remote UGV ground vehicles already? Can we not remote control a semi carrying supplies in Iraq from Utah? I would think this would be the first step already taken towards full autonomous operation.

Maurice is right. The price is coming down and the future is not distant -- maybe three years. A major manufacturer of automotive sensors plans to drop their price from about $100,000 to $500 and put it in main-stream cars. I am looking to produce an autonomous vehicle for a total price of $10,000. See the story "Open-Source Warfare" in the November IEEE Spectrum about how the Internet helps Iraqi terrorists stay ahead of the US military. The same thing will happen with autonomous vehicles.

Well I got it to work flawlessly after downloading a separate player and codec pack from free-codecs. I just installed Vista a week ago. I think VLC is using WMV11 codecs from the OS and the perhaps Vista DRM stops playback. Awesomeness.

I seem to remember some discussion after the last challenge claiming that there was a commercial entity interested in doing their own automated vehicle competition for "entertainment" and prize money.

Anyone remember who / what that was?

Dr. Tether was claiming in his speech that the intent was to foster creativity and innovation in the technology. He also noted that DARPA was not going to pursue this technology beyond what it does for the events.

Im not a social econ / poly sci major, but putting on a better show would certainly not hurt the event or its claimed objective. Besides, I thought Jamie and Grant are entertainers, not military analysts.

As for the next challenge, how about DARPA taking it up a notch and giving the autonomous vehicles a realistic "hot" combat scenario. Roadside explosions from IEDs blowing up a convoy lead vehicle (or simulated one and not the contestant vehicles), hostiles trying to highjack them, hostiles trying to ram them with trucks, being shot at by hostiles, and so forth.

Firstly, I am hoping someone can explain to me how robot
cars will save lives in military situations. I understand the arguments about
reducing traffic fatalities in civilian situations but I cannot understand the
claim regarding military lives.
------------

From what I understand from friends overseas in Iraq, most of our soldiers that are kidnapped / killed are from lightly armored convoys (we dont run tanks and apache's along side our spare parts / food shipments). A majority of these deaths involve soldiers driving in vehicles.

DARPA is trying to jump-start technology that reduces the number of humans required to drive vehicles in dangerous situations. If a roadside bomb detonates a robot vehicle carrying medicine we are out some money, not a human life.

In the convoys that absolutely require humans, autonomous cars can "lead" the group and take the roadside bomb blast ahead of everyone else.

Posted by: honest joe to Rules:changing the rules mid event?

exactly. almost good enough, all of the teams fielded vehicles that were almost good enough, it is called research and development. non of the vehicles will ever go into production as is, each is or was a prototype, more reasearch is needed more development required. that was the point of the exercise as i read it, to stimulate the reaserch and development of uav.

as my wife says it, "there were some scary vehicles out there, our did good but with glitches even if we completed all the courses"

if the point was to stimulate development and reasearch why change the rules? this is only going to make teams / research facilities feel that entering is pointless. so dont enter

will that feeling provide the best equipment for armed forces around the world in the next ten years? the timescale for research to full deployment of any concept is what? at the end of compotition? i am not sure on that!

this is not a game i totaly agree

this is serious stuff millions of lives and dollers are at stake
its not a game were its your ball so its your rules
try changing the rules at half time in a fifa match!
it will lead to confusion and resentment. and that is what has happened here.

I have to agree with LeenSTL this was not a game of horseshoes, having participated today for more then seven hours with the bots as a traffic vehicle driver you get a real taste of the what ifs when you are face to face with a vehicle like Terramax, I had to take evasive action to keep from getting run over today.
That is the reality of the judgements made by DARPA this week keeping this event as realistic and as safe as possible, it would be impossible for DARPA to please everyone, as for me I am very happy in the way they handled the teams that were almost good enough.

It was a great event but the online coverage was sub par. The high bandwidth video was somwhat jerky and the sound seemed slow too.

I wish there had been a video stream per bot from the chase vehicle. In such a state of the art event, that should be possible.
The map tracking and status board where also not updated for me during the race.

I wonder what the next level from here is? I would like to see:

- Traffic lights (normal + yellow/red blinking)
- Cars in the parking lot, at least the spot to be parked in has to be surrounded by cars or concrete barriers.
- Parking lot pedestrians (bots)
- Fewer to no GPS coordinates(maybe only start/finish), instead use road names, destinations etc....
- More human traffic

Other Final Event stats that would be interesting to see:
- actual distance travelled by each bot (*should* be the same, but maybe some tried alt routes at jams),
- speed on each segment of roadway (full list on every pass).
- maximum speed on each segment.
- overlay of all teams positions in absolute time on the course - animated map.

Split it and upload it to mediafire. Mediafire allows 100 MB/file, so... because you're probably using linux, I'd do: split --bytes=100m [filename]

Edit: Actually, I'd recommend you split it to 99m, because they might calculate megabytes differently.

Save Lives? What about a robot car with a bomb?

Posted by: Adak to Technology:Save Lives? What about a robot car with a bomb?

If you recall from Desert Storm, we had the Revolutionary Guard pinned by our advancing tanks, if they had just kept going. Unfortunately, they stopped for some much needed sleep, and the RG and their supplies, slipped away. Many could not be found again. Schwartzkopf had a fit! :)

If some of those tanks had been robotically controlled, then the RG would have indeed been captured/killed. No sleep needed.

No, I don't believe it will be cheap, and I don't believe it will be commonly available to both sides. You're looking at $300,000 worth
of equipment on those cars. Sure it will come down, but not to the point where every Iraqi insurgent who wants one will be able to
afford it - let alone have the expertise to set it up and program it.

What prevents such catastrophes? Same thing that now prevents suicide bombers driving trucks with bombs in them into target-rich environments. I don't
see a lot of difference between the bot driving, and the suicidal human who puts a rope on the steering wheel and a weight on the gas pedal, after lining it up
right for the target.

Either way, the truck has to be stopped by something besides just sa fire, which would kill the driver.

I doubt that there will be any jamming in this scenario. It is true that the bots have only seen other sensor-less vehicles, I doubt that the sensors would intefere with each other due to the angles where they are pointing.

It seems that team Dad is a winner already based on the sales of their new lidars!

I am most interested in how these bots will fare when they pass eachother on the course.
In prior events and at the UC Qualifiers, the bots were operating on their own.
They were the only bot in the area. None of the stunt cars had active sensors, AFAIK.
Does anyone know if the active sensors will function in the presence of other sensors?
Are any of the teams operating a completely passive solution like Team DAD in 2004?
Ironically, it is the Team DAD folks who have the "noisiest" sensor out now that many teams are using.
Will DARPA include "jamming/confusing" LIDAR signals on the course today?
I think the next Challenge should require silent/passive solutions so that autonomous vehicles in unfriendly environments are not broadcasting their presence.

Firstly, I am hoping someone can explain to me how robot
cars will save lives in military situations. I understand the arguments about
reducing traffic fatalities in civilian situations but I cannot understand the
claim regarding military lives.
I am assuming that the technology will be both public and
cheap. In a military situation both sides will have access to it and so I see
no net benefit.
Furthermore, as has been seen in Iraq, significant civilian
casualties can be caused by bombs located in cars with suicidal drivers. With
robot technology a suicidal driver isn’t even required. A robot car laden with
explosives could drive right up next to the Rose Parade or the New Year’s Eve crowd
at Times Square.
Can someone please explain what will prevent such
catastrophes?

Unless they are considered confidential for some reason, it would be fun to see some followup postings to summarize statistics (maybe in one table offering easy side-by-side comparisons) about the entrants in the following areas broken down by vehicle and grouped by vehicles that 1) finished 2) made the finals 3) entered the qualtifying event

1) total price of vehicle and all components used (onboard)
2) number of sensors of each various type
3) number of CPUs, RAM, and persistent storage capacity
4) which OS platform? (why did skynet have to stop and "recycle" so many times? are they running windows?)
5) what is their programming "stack"? (how many custom drivers to interface to the sensors/actuators, application server & number of instances if used, database type and number of instances if used, messaging middleware if used, programming language, etc)
6) some classification of their algorithms (how distributed are they, computational distance (modules) between sensing and acting, which modules are using the most compute power, degree of self-learning enabled during the competition, summary of approaches to which data can be ignored or prioritized in what order)
7) which part of their software module does each team feel they would focus on most if given more time to prepare?

OK last comment for now-- I meant US engineering college Computer Science curriculums have been exceedingly boring.

I speak from experience at Cornell in the early 90s when they bored me right out of the program into economics-- I take responsibility for that too and have many fond memories and successes to celebrate anyway, but days like today while I watch these robots wish I would have stuck it out to get a PHD and have more chances to participate in design projects like this instead of building financial applications...

In my case "youth is wasted on the young" -- kids don't sell yourselves short and stick with your dreams no matter how hard those professors try to turn you off with classes that don't seem to have any practical application! There's room for both the students and the curriculums to step up and keep the US economy competitive and stop the offshoring of all engineering work from becoming a self-fulfilling prophecy.

I enjoyed the commentary so much that I am going to make sure to send the Mythbusters a note on their forum if they have one. Trust me, it's rare to hear technical chat that is even mildly accurate, just view some of the team videos done by TV interviewers. They will say things like "the robot is controlled by the USB drive", that is almost an exact quote. Besides, if Jamie hasn't seen it he can at least figure out how it would be done, so kudos to DARPA for going with the Mythbusters, and kudos to the Mythbusters for being cool.

- I'm excited to see all the multicore solutions (40, 30, 9 mac-mini's,
etc) being demonstrated. I feel the current generation of programmers
(including myself) in the business world right now are not prepared
well enough to leverage the coming power of dozens or thousands of
simulatenous threads distributed across emerging compute grids. I hope that this race will drive multicore
programming into the mainstream faster and help increase the skillset of programmers everywhere.

- I look forward to Numenta's furthering of their HTM capabilities and how their predictive memory model will be applied to influence future iterations of competitions like this.

- I'm very impressed by the teams and the finishers, I can imagine they are all salivating for more computing power to allow exponential levels of sophistication in their next entries. I can't tell you how excited I am to see history in the making and the development of ever more capable machines.

- Cheers to all the teams, to DARPA for helping inspire the US to grow/maintain its technology expertise to keep our economy competitive, and especially to my alma mater's entry "Skynet" for being among the finishers. (Go Big Red!)

Great event for the teams, current and future innovators, the US, the world!

It's a hot topic in schools everywhere, even in the community college where I teach there is interest in providing some robotics orientation. Budgets are not huge but there will be some exposure at least. Every teacher in every programming and engineering class should be making sure their students are exposed to these competitions.

I'm sitting in Seattle this morning and have been glued to the live web feed for over 6 hours with barely a break...

Main areas I'm pondering:
- How long until the next round and ever more realistic environment? (victorville was less than suburban, let alone urban. Where are the buses, streetcars, parked cars along the roadway, pedestrians crossing streets, bicycles in traffic lanes, etc?)
- I can only hope that all the lazy high school or younger kids out there in the USA get off the couch and video games and break out their mathbooks! Software design is fun and you won't get a shot to play with these kinds of robotic "toys" unless you pay attention, work hard in school, and go find a good engineering program for college. You are not entitled to the same quality of life your parents had... you have to go earn it yourself and be competitive in a global economy!
- I hope that US engineering colleges are waking up to the fact that your curriculums have been exceedingly boring for too many years and contribute to the shortage of enrollments and grads. Its going to be the real world applications and practical implementations of the theory like this challenge that we need to raise interest and increase enrollments again.

Having the Mythbusters team was a great idea, they were often correct on technical concepts. Few in the mainsteam media could even understand the concepts much less explain them.

I get an empty Status Board, a Tracking Map with no vehicles, and nothing on High-Bandwidth Video.

Fortunately, the Low-Bandwidth Video works, except that it took me about an hour to give up on high bandwidth.

I'm trying with two computers running the latest XP updates, and one running Wn 98.

If anyone is getting any of these functions, please let us know. In the last challenge, the status board started working about a quarter way through the event. It's too late for that, but maybe they'll get it going by half way through this one.

Posted by: DaveB to Rules:changing the rules mid event?

H. Joe, I agree they seem to change the rules more than necessary, but they DO have that right, and from what we've seen on YouTube and TGDaily a lot of vehicles needed to be eliminated.

What's worse is that REAL speed limits are no more clear than those on most highways. In the last Challenge, it was apparent that some vehicles were getting away with going faster than the mission data file allowed. In fact, if CMU had allowed their backup vehicle to go faster, they might have won (their primary entry had problems that prevented it from attaining its target speed).

Maybe DARPA has already said in one of the meetings, that ANY speeds in excesss of the limit will be cause for elimination, but if not, they SHOULD, and should enforce it. If all entries behave, and observe the speed limits, then the two million dollars may be won by the entry with the fastest acceleration and stopping. Hmmmmm

In my opinion, the worst rule change was when they announced, for the first Grand Challenge, that the field would be pared down to 20 cars before the final test. Up to that point, it was supposed to be a real "race", open to all comers, so that was the first introduction of their subjective evaluation being used to eliminate teams. Since then, it's always been clear that their opinions would be used to decide who gets to race.

Gulag — Thu, 01 Nov 2007 08:07:00 GMT

Posted by: Gulag to Rules:changing the rules mid event?

I am not convinced that any rule changes occurred during the selection process. At first glance, it did appear to be somewhat arbitrary. The early teams that were eliminated consistently failed to demonstrate capabilities or showed unsafe behavior. Obviously, DARPA didn't want to put teams into the race that would potentially cause a more capable team to be eliminated due to a collision. Unfortunately, the scoring process was not and will probably never be published so it appears biased. Everyone was given an even slate of qualifying runs at the beginning.

As for the final competitor count, DARPA has always stated that they would field up to 20 teams. Selecting fewer is inline with everything that has been stated throughout the program.

DARPA did setup courses that violated many of the stated rules. The start chutes on Area B were significantly less than the 1 meter clearance on all sides of the vehicle based on the stated maximum vehicle width. Likewise, the setup on Area A was a joke initially with a concrete barrier on a 12 ft lane. Given a mandatory clearance of 1 meter on both sides of a vehicle, the 12 ft lane wasn't really plausible for vehicles that were near the maximum vehicle width.

Obviously, they were looking for human behavior and not rule rollowing.

While many teams attended the event it seems that the darpa directors were haphazard and random in the process of selection. Once again dod proves that they cant act fairly.

This is going to have a nock on effect, next time teams will not enter as the randomization of results is going to make the effort pointless.

Why o why at the last minute change finalists from 20 to 12?

Did they want to get a round of golf in before going back to work?

Sorry but I think there is some stupidity here. When you publish rules and guidelines even the judges have to follow them.

Not likely, Dan, as neither of the first two challenges were even broadcast live in the US.

During the first challenge, one of the colleges (Carnigie Mellon, I think) broadcast live on the internet, which worked out quite well.

During the second challenge, DARPA hired a company to provide live pictures and position data, which worked out very poorly.

In neither case did we learn what would be available untill the last minute (couple of days, actually).

The normal media seem to prefer editing a show for later broadcasting, possibly because they have no experience with this particular event, and each Challenge is different than the last.

Keep your fingers crossed in hope that SOMEone will do a webcast of this Challenge, and keep your eye on this forum, probably in the media or other thread since we hope to see the NQE, as well as the Final Event.

Hi Preston,

The autonomousvehiclemfgrs newsgroup was overrun by spammers and has been shut down. I am still publishing info about teams and their sponsors several other places. My on-line column in Control Engineering Magazine http://www.controleng.com/index.asp?layou t=blog&blog_id=1180000318 is one of them. Control Engineering Magazine is the premeer technical journal for control engineers and automation engineers. Many teams have a PR person who sends out press releases every week. Please put me on your media distribution list for these press releases and whatever else you send out to the press.

My contract with Control Engineering Magazine allows me to write for other publications that are not competing for the same sponsors. Do you pay your writers?

Sounds like an interesting project.

What would you like my CE readers to know about your project?

"Please put me on the distribution list for information you would like to see published" - Can you please elaborate on this comment.

Do you publish articles or written work? What type of work do you publish? We are developing http://www.adison.edu and her sister site http://www.nassonu.edu and not only do we need work to be published but we also want to publish good work.

Through 2008 we will be adding student collected databases of information for the internet to use and hope to do an article publishing system where we can show off unique articles/stories of great influence.

Any comments can help us greatly...

Questions about lane descriptions in the RNDF

Chef — Thu, 13 Sep 2007 09:29:00 GMT

Posted by: Chef to Rules:Questions about lane descriptions in the RNDF

Page 8 of the general rules says:

Driving in difficult off-road terrain is outside the scope of the program. Off-road
navigation in an unpaved area, travel along roads with potholes, and travel along a dirt
road are within scope.

Page 10 of the document about RNDF_MDF format says:

The <optional lane header> contains *SOME* or all of the following elements:
[...]
- left_boundary left_boundary (string ∈ {double_yellow, solid_yellow, solid_white, broken_white})
- right_boundary right_boundary (string∈ {double_yellow, solid_yellow, solid_white, broken_white})

FAQ C.4 states:

C.4. Will all the lane boundary lines listed in the RNDF actually be present in the physical world?
DARPA’s intent is for the RNDF lane boundary descriptors to match the actual physical lane markings on the ground. However, DARPA cannot ensure that this will be the case in all areas, and as such the RNDF shall take precedence over the physical ground markings in conflicting areas.

... and after having read the sample RNDF file, my questions are:

Are these statements true?
- DARPA intent is to have all the lane markings on the ground appear in the RNDF.
- If a line marking cannot be described in the RNDF (e.g. a broken yellow line, or line markings between entry and exit point) DARPA intent is to hide or delete them.
- If a section is unpaved, in the RNDF file lane boundary entries won't be present.

Shawn

Spectators are welcome. NQE is 26 to 31, October. Challenge is 3, November. See third and fourth paragraphs on the Urban Challenge home page:
http://www.darpa.mil/grandchallenge/index .asp

They don't address which team will go when, or seating, but my guess based on previous challenges is that there will be a spectator area with seating, and that only press will be allowed near the course in other areas. Since they'l be doing the same course four times (as I recall), the start/finish area where the spactators are will likely be far and away the best place to watch from. I doubt they'll publish a schedule of start times for the NQE, but maybe. Anyway, who knows which teams will be the most interesting.

Hope you enjoy the events

We live in Northern Virginia. My 7-year-old would dearly like to come and watch both the NQE and the Finals. Can anyone comment on the opportunities for spectators at the NQE?

Will there be seating or will we kinda jog around to witness different parts of the course?

Will a schedule be published listing what dates each team will complete in the NQE? If so, when will this schedule be available? It's a long trip for us and i'd like to make sure he's able to see his favorite teams compete in the NQE.

Thanks!

have any of you participants considered the ethical implication of taking part in this competition seeing as it is intended for war use. while some of you may tell yourself it is to save lives try to realize how it will only make it easier to sell warfare to the voters when none of their own die. try also to realize that it is for a group of people currently engaged in megacide in Iraq based on lies. can you honestly say you are without guilt if you aid them?

some of you might tell yourself that you know all this but take part anyway knowing you would never give the developed technology to military use. but if that is the case compare it to the power of the statement of not taking part in it or taking part but using a vehicle clearly marked as not for war use. if you are afraid to make such a statement have you not already surrendered to the service of the evil they represent?

although the analogy will not be flattering, it can however accurately be compared to n a z i engineering efforts. let it not be said that you didn't know.
(I write n a z i with spaces because this forum automatically censors that word. food for thought)

this message has been posted before but was deleted. again food for thought. if deleted again I will make a letter writing campaign to every last team taking part in this competition. I'm going to tell these people what you don't want them to know. where we go from there is up to you.

DGC III expected results

Posted by: Seth Cabe to Urban Challenge Final Event:DGC III expected results

I can only guess that level of success for this race will be somewhat similar, though probably better, than DGC 01. It is really all up to DARPA though. But Dr. Tether seemed to suggest this was not to be a cakewalk. If I were a betting man, I'd say this will be mostly a learning and testing experience for DGC IV, where someone might actually win. Just my 2 cents, I haven't been following this too closely lately.

We are the bluish car in the lower left hand of the cover page picture. MIT gave us their mold so we were pretty confident in our aerodynamics ;). Here is another pic of the car in action:

We did very well. We used Back Side Contact (BSC) cells which exceeded our every expectation. Anyways, I don't want to get too off topic. We have the capabilities to produce near-aerospace grade composite and reasonably well machined/welded titanium structures. I would be willing to entertain offers to produce or consult regarding our expertise on a non profit basis for DGC teams. I wish I could outright donate materials, but we aren't in any sort of position to do that! Also, I would love to entertain any general questions and help as best as I can any teams out.

implying that I'm a troll doesn't make it so.
how do you figure that calling the killing of thousands massmurder is a distortion?
and how do you figure these will save lives?
as I see it, robot warriers will just make mass murder easier to sell to the voters thus costing many more lives.
I'm sure hitler told the scientists that their patriotic efforts were saving great german lives too. but of course that's a very small truth covering a massive lie.
if you take a look at some of the photos used as illustration for this competition it shows military vehicles running in a desert urban environment. calling it urban makes it just palatable enough for the participants here to kid themselves that it has something to do with civilian car systems. so they can close their eyes to the evil they do so they can have fun playing with their toys.

this is a very deadly game, gentlemen. calling me a troll wont change the truth.

I take it that you don't mind distorting the facts a bit, ie, mass murder (other than what Saddam Hussein did in his reign), "maybe a million people", comparing this event designed to save lives to Hitler's efforts. Perhaps if it were a contest to save insurgent lives then you'd go along with it?

At any rate, conventional wisdom is that trolls should not be fed, so I won't attempt any further rational dialogue with this troll.

Have you taken the time to compare the situation to n a z i engineering efforts? Should those scientists have reconsidered? should you?

Sick LD LRS Question ...

Jason — Wed, 16 May 2007 02:56:00 GMT

Posted by: Jason to Technology:Sick LD LRS Question ...

Hi everyone,

I was hoping maybe someone out there is familiar with the Sick LD LRS
1000. I am currently working with the unit, and I am writing a driver
for it. Although I can successfully setup a TCP connection with it and
send it a command, it fails to respond. I've verified with Wireshark
that my code is behaving correctly. Messages are being properly
constructed and pushed into the network; however (despite receiving the
message), the Sick simply does not respond. The message I am sending
is shown in the telegram protocol manual for the Sick LD-OEM/LD-LRS.
Since the manual is riddled with errors (for instance, they give the
wrong port number, mislabel packets, and never specify the default IP
of the Sick LD LRS), I believe the issue lies with their protocol
specification in that document. Has anyone else had a similar issue
or experienced this?? Were you able to find an accurate specification
for the Ethernet protocol for the Sick LD LRS. Additionally, I should
note that I have had previous experience implementing drivers for Sick
lidars, and have also had issues with their telegram protocol
specification before; however, in those cases, I was able to identify
and resolve the manual's errors.

Has anyone else experienced this? Can anyone confirm the validity of the telegram
protocol in that manual?

Thanks so much,

Jason

Specifically the method/s concerning temporary import and DOT and EPA regulations and or the exemption process. Any advice and or suggestions would be most appreciated.

Sparky,

You are familar with the Track "A" and Track "B", but there is also another group. Since we are lettering things, I am calling it Track "C". This third group are teams that are not on the DARPA list but are still working on solving the Army's problem, which is actually the point of it all - race or not. We are continuing to use the Urban Challenge rules so that our vehicle will be ready for the next race if no one wins this one.

Over the years we have had many vehicles of many types. The vehicle we are building up now is an M-215, AGV WENDY DARLING, is Lots of work left to do on it. Check out our website and our Yahoo news group linked from our home page. I will try to get some fresh pictures up in the next couple of days.

I worked on the driverless vehicle project that was before the Grand Challenge. It was at the end of the first Gulf War 1990/1991 and the question was how to get on driver to drive a half dozen ammo trucks at one time. Later that turned into the DARPA Grand Challenge.

Hi everyone,

Lots of things have changed.

We are currently a Track "C" team - that is a team working independently on solving the driverless problem, no prize money, no grant money, just a lot of lives that can be saved and a cool engineering / educational opportunity.

Considering the rules of the race, it looks our automatic guided vehicle AGV WENDY DARLING is the best choice out of our three vehicles to focus on. It is a classic M-215 Army truck with the shorter of the two options wheel base. Light weight by today's truck standards it gets pretty good gas milage.

If you are looking for a team to join so that you can keep working on solving the problem, please consider joining my team. We are getting ready for the next race.

lane_width value for 4.5m?

The RNDF specifications say that the value for lane_width should be an integer.
The 4.5m width specification equates to about 14.76 feet.

So should we use 14, 15, or 14.76 as a value for lane_width?

As Phil Stevenson says, at: http://gis.ou.edu/pipermail/okgis/2004-Oc tober/000266.html

"Every time I use the term WGS84 I really mean ITRF00 because there is not a way for me to determine an actual WGS84 position."

Many high-accuracy GPS systems use the OmniSTAR corrections. Their site at http://www.omnistar.com/faq.html says:

"A. OmniSTAR VBS in North America is on the NAD83 datum and ITRF00 in all other OmniSTAR world areas. OmniSTAR HP and XP are in ITRF00, worldwide."

Since VBS is their least accurate system, you can assume the position reported by your GPS is in ITRF00.

It wasn't the ITRF00 that confused me so much as DARPA's replacing "float" with the undefined "fixed". To me, fixed is an integer quantity with a virtual radix point. If you represent latitude or longitude with a six digit integer, your maximum resolution is 1.5 second. To get better than that, you can give an integer as a Northing and an Easting as is done in the UTM system. That only works if you have a grid reference, which was not specified.
What DARPA really means by "fixed" is %.6f in C. This is a double precision number, not an int.

Did anyone notice the change to the RNDF format that DARPA made on December 1, 2006? Latitudes and longitudes for waypoints are no longer given in degrees. They are to be six digit integers in the ITRF00 reference frame. The sample_RNDF supplied by DARPA has not been updated to this format and no example of it is provided. DARPA requires that the site visit RNDF (due March 16, 2006) use this format.
From what I have been able to find on this format (International Terrestrial Reference Frame of 2000), it appears to use UTM (Universal Transverse Mercator) coordinates. However, UTM requires a grid reference and there is none in the RNDF format. The RNDF format specifies negative numbers for longitude, but this is not done in UTM. Northing is a seven digit integer, not the six digits specified.
Does anyone understand ITRF00?

HMR3500 True Point Magnetic Compass from Point Research Corporation

I'm using the HMR3000 with success. Calibrating the device only took an hour and the results have been reasonably accurate and responsive. I just use the RS232 interface. I don't use LabVIEW for anything since it is unnessary overhead on top of the very fast real-time features of XP. My software is multi-threaded Microsoft C++ and rides down on the drive shaft such that even though I do 2 dimensional laser processing 20 times a second accurate to 1 inch at 80 feet, satellite, HMR3000, actuator and stepping motor control for the brakes, gas, gear and steering, the CPU is busy only 15% of the time.

"It would seem to me that it would be better to perform fine-tuned lane following using visual systems on the vehicle that do not depend on external signals. What do other people think of this rule?"

If I were a guerilla and I knew that an autonomous vehicle was using visual cues as its primary means for lane following, it seems like a can of paint would be all that I need in order to paint over existing lines and paint some new lines that would run a convoy off the road.

I took a drive out to Johannesburg this weekend. The streets are paved and grided perfectly, but unfortunately not wide enough. If I read the sitevisit requirement correctly one needs 2 lanes each 4.5 meters wide = 9m total width.

Good luck finding 4 'real' streets anywhere that intersects to form a 250 - 500 m loop and are 9m wide.

The only thing I can think of is to reserve 100 x 120 m portion of a large (stadium) parkinglot and stripe it with lanes for the event... (and have the vision system go crazy seeing all the striped parking spots)

EZ Magnetic Compass

arturomdn — Thu, 18 Jan 2007 08:59:00 GMT

Posted by: arturomdn to Technology:EZ Magnetic Compass

A digital compass uses tilt compensation to estimate heading, and tilt is affected by acceleration/deceleration of the frame of reference.
See this article about how low cost devices estimate heading. Minor errors in heading can accumulate and result in big errors if you are using it to perform dead-reckoning in GPS denied situations.

http://www.ssec.honeywell.com/magnetic/da tasheets/lowcost.pdf

"ACCELERATION EFFECTS
Any acceleration of the compass will effect the tilt or
accelerometer outputs and will result in heading errors.
An aircraft making a turn will cause the tilt sensors to
experience the centripetal force in addition to gravity and
the compass heading will be in error. However, for most
applications the acceleration is small, or is in effect for a
short duration, making a magnetic compass a useful
navigation tool. Inertial reference systems would be the
solution for applications that can not tolerate these
heading errors. These systems would weigh, cost, and
consume power at least 10 times more than those of a
strapdown magnetic compass."

Thanks Art for your suggestions. A portion of a parking lot might be an option. Ideally I'd like to use (painted) lanemarkings instead of cones for the road definitions. I wonder if we could lobby DARPA to use a loop with two 3 way tees instead of a full 4 way cross. That is easy to find. The drive ways around most industrial buildings fullfill this requirement and all combinations of going straight, turning right and turning left can be done. Ivar

EZ Magnetic Compass

Posted by: Bong to Technology:EZ Magnetic Compass

Hi,

I am again evaluating another type of Magnetic Compass; EZ-Compass-3A. This instrument feedbacks Pitch, Roll and Azimuth value. I am just wondering if anyone in the forum have experience with this kind of sensor. Has anybody in the forum made a LabVIEW interface to this sensor?

Any help / advise I would greatly appreciate.

kind regards,

Hi Ivar,

We have been wondering the same thing. We are considering securing permission to use a parking lot in private property.
It happens to have a 4-way stop with white lines already there.

There is a large parking lot in the Orange Coast College campus, do you think they might let you use a section?
Aerial picture here. Parking lots around the Pacific Amphitheater look interesting too, they have some builtin stop lines,

Fitting the vehicle with do-it-yourself drive-by-wire is not for the faint of heart. You might save money, but
you won't save time. Reading some of the technical papers from previous events can be helpful should you
decide to do it yourself. For a specific electric motor for steering actuator and pictures of how it was attached
to the steering shaft, see our team technical paper (click here to avoid annoying space in URL below):

http://www.darpa.mil/grandchallenge05/Tec hPapers/Austin_Robot_Technology.pdf

Several teams reported burnt steering motors/controllers prior to the site visits in 2005. Make sure you size
the motor properly. We decided to use a high torque (high current) motor with a 10:1 gear head, this allowed
the actuator to turn the wheels quickly even when the engine was off (no power steering). We also selected
a motor that had a built-in encoder and a controller. We were happy with our choice.

EMC has servo motors for steering, plus some parts of their system is electronic for automatic transmissions etc. If you just want to see the basics of a closed loop steering system you can go to the Robotek site and see if they still have the link for building a full size R/C car. It is short on details but shows an overview.

IMU's

Posted by: Militoy to Technology:IMU's

The caution I noted regarding Kalman filters related to the differences between firmware algorithms used in airborne IMUs and those designed for use in ground vehicle applications. For instance - PC Flight Systems makes a low-cost MEMS IMU called the eGYRO-XP, which is designed as a strap-on electronic gyro and EFIS module for General Aviation use. If installed onto a ground vehicle and calibrated, when the vehicle is moved into a pitched or rolled attitude and held static, the IMU’s firmware will within a few seconds “correct” the data baseline and establish a new “straight and level” baseline at the new attitude. The Kalman filter algorithm used is not designed to accurately interpret a long-term static pitch or roll condition – since those are not conditions encountered during normal flight dynamics. The data could be corrected by post-processing – but why not just select an IMU designed for ground vehicular applications?

As far as acceleration goes – a prudently-designed IMU made for vehicular applications should have a higher level of shock and vibration tolerance than one designed for flight dynamics – except perhaps a flight IMU designed for AUF or AIF environments, or similar.

Posted by: Marcel to Technology:IMU's

@ Miltoy,
Most IMU's are excellent for ground vehicles, since there are less extra accelerations (other than gravity), that may make the reference for roll and pitch inaccurate. Some IMU manufacturers (such as Xsens.com) integrate IMU's with other sensors, such as vision, GPS and more. You can get specifications of these new products on request.

Kalman filtering is the most important part of an IMU, since most IMU manufacturers use the same MEMS sensors.

All the way at the bottom of the program are the argv's which pickup the name .txt and all. I have gone through the code and can not see where the program writes any report or output data file. I am beginning to think this is prototype code and just loads up the data in the two files. It is up to the users to actually write the code that does real work.

If the program does write out a map or something how about a screen shot?

Posted by: DaveB to Technology:RNDF MDF Parser C/C++ Code

MarkIvin asks, "My input txt files still have tab characters, do I need to change them to blanks or some such thing"

Nope, the latest RNDF/MDF format definition (12/6/06) requires tab delimiters. See the Rules page.

It looks possible that your interpretation of the file name is different than the programmer's. The sample MDF lists the RNDF file name without a suffix, but the posted RNDF file name has a .txt suffix. My guess is that you left the .txt suffix on the file, but the programmer interprets the file name in the MDF literally, so it's looking for Sample_RNDF_Rev_1.2 rather than Sample_RNDF_Rev_1.2.txt

It seems like I remember DARPA addressing this naming problem, but I can't find it in the FAQ files. Personally, I think if they provide an RNDF file named Sample_RNDF_Rev_1.2.txt then that's what should be in the MDF, but maybe that's too much to ask. I suspect they only added the .txt suffix to simplify publishing it on the net, but sheesh!

HI,

OKAY, I was able to get the strtok() deprecate thing bypassed with some help from someone on the C++ forum who had me add a define line.
#define _CRT_SECURE_NO_DEPRECATE 1

Unfortunately, that left me with one other error LNK2019. The error said it could not find the external reference to _WinMain@16. After research I was able to figure out how to tell the LINKer to replace /SUBSYSTEM:WINDOWS with /SUBSYSTEM:CONSOLE, and I was able to build an .exe, but I don't know if its working.

I know I can not complain about freeware, but when it came time to run the code I was guessing about the input and output I should see. Here are some of my experiments, none of which met with success. My input txt files still have tab characters, do I need to change them to blanks or some such thing. I just downloaded the files straight to the work directory.

What exactly is Usage: RNDF-MDF RNDFfile MDFfile trying to say?

I can't get the parser to compile on the newest MS version on C++ because strtok() is deprecated. That is MS VS C++ Express which I was able to trial for free. Can someone give me an .exe or point me at some freeware C++ compiler that will build the parser? This is what I posted on the MSDN C++ Forum...

"I have a program reportedly compiled with VS C++ V6 that I need to compile, (no using the new VS C++ Express. The only major error message preventing the build come from deprecation of the strtok() commands in the program. I have searched all over the internet, and gotten advice to swith to strtok_s or turnoff the deprecation. I can't find a step by step detail instruction on how to turnoff deprecate in VS C++ Express, nor can I find any step by step conversion instructions for a replacement command that works. For example, if I do what the compiler says, change the strtok to strtok_s or _r even the resulting build does not even recognize the commands. I am hoping that this is a simple matter for the experts among you. I just don't understand why I can not find a cookbook solution to avoid posting a question. "

-----
Also, another angle I am working is I have installed a Fedora Core 6 Linux machine under VMware Beta . But I don't have a chops yet for doing a build compiles on it yet. Work in progress.

Mark,
If you have not found a vehicle yet, some of the newest cars, especially the European version of then are drive by wire. The EC has mandated that traffic fatalities be cut in half by 2010 and to meet these new safety standards car companies are having to go to active safety systems which amount to computer control of the entire car. They have exhausted the life-savings that can be done with passive safety systems.

In this race DARPA does not plan to use the e-stop to prevent collisions, only to prevent the vehicles from leaving the race area. They are going to let the vehicles do what they do to see what that is. Considering the NY TAXI driver behavior required and illustrated at the Participants Conference, that any vehicle that is not prepared for contact is not prepared for the race. One of the rules is "no external fuel tanks" in this race, which should be taken as a hint from the race officials. TerraMax is is this race. Expect to meet it at the interesections and be prepared to avoid it. The new version is one axel shorter. Be concerned about the smallest vehicle too. You don't want to get the little one caught in your vehicles teeth and have it stop the two of you. Shock to the electronics may be from the side this race. Last race it was from below.

I got the impression from the first site visit that if your own vehicle were to contact another, that would be the end of the race for your team. If another team's vehicle were to strike yours, a 5 MPH bumper (standard on all US-sold vehicles) would help prevent some of the damage - but only if the other vehicle were to contact at under 5 MPH - and only if the contact was directly on the bumper. If you're going to rely on protection from "springy bumpers", better put them 360 degrees around the vehicle! And - better hope that "Terramax" isn't involved in the accident!

From the acceleration spike readings I have seen for solid contact with anything, springy bumpers, shock absorbing bumpers look like a very good idea for protecting your vehicle and its contents. Model T bumpers were spring bumpers good for 5 mph crashes.

magnolia,

You have to submit it to grandchallenge@darpa.mil and wait for them to publish it in the FAQ for the answer to be official.
- or -
Ask yourself if the California State Police would allow you to do whatever it is you are wondering about. If you would get a ticket for it, you might want to avoid it in the race. After several phone calls about the race the California State Police have said to use common sense in keeping traffic moving.

I hope this helps you. Which team are you with?

Hi I was wondering if U turn is allowed under the following conditions:
1. when stop sign is present on the intersecting traffic but not on the main traffice. Left boundary is double yellow.
E.g. In sample map Waypoint 3.1.7

2. When the segment ends with a stop sign and exits to next segment. Left boundary is double yellow.
E.g. In sample map waypoint 3.1.14, 9.1.2

3. When the segment ends with NO stop sign and exits to next segment. Left boundary is double yellow.
E.g. In sample map waypoint 10.2.8

Any one at Darpa?????

Salty — Mon, 20 Nov 2006 11:30:00 GMT

Posted by: Salty to Rules:Orphans

Large vehicles like semi-tractor trailers are allowed to "violate" lane restrictions and markings in order to make turns that could not be done otherwise. There is a practicle interpration element to enforcement. The standard used is to do so safely. In order to make right turns, the vehicle may start in the right lane, swing into the left lane and then start turning right coming into the oposing traffic lane before ending up in the right lane. An interesting judgenet situation occurs when another vehicle obstructs the turning vehicle. Since these vehicles do not have the abilityu to see well to the rear, it is unsafe to back up without calling the police:-( A judgement has to be made about waiting or trying to manuver.

Thank you very much for the reply.

While the sensor is turned ON, i can see the HEXA data are updating too. But I want to know the meaning of the HEXA data so that I can pick up the specific data I need from the sensor which is the Azimuth.

I believe our sensor team has selected the Honeywell TruePoint as a backup to our fluxgate/FOA based-IMU. We were using a KVH C100 previously, and I haven’t worked with the Honeywell unit myself, but according to the manual, you need to use NI-VISA for serial communications. If you’re using LabVIEW, the Example Programs under the Help section describes a Basic Serial Write and Read routine, which should help you. The specific serial communication protocol should be outlined in the Honeywell manual and programming guide.

Your selection of a specific embedded controller should take into consideration the experience and background of the students, as well as the user-friendliness of available support materials. Better to start them out with a simple stamp controller, or a lower-end micro like a Rabbit 3000, and then build in functions until they outgrow its capabilities - than to frustrate them with too much complexity at first. The PIC line of controllers from Microchip would be on the next level up from the Z80-evolved Rabbits, and are extremely well supported.

Further to above – My comment isn’t intended to impugn Bill’s suggestion in any way. The Cypress PSoC flash micros are robust products, and the one he suggests has lots of I/O, which is helpful for robotic applications. Only “BSM ACS” knows what level his students are starting from, and it’s been my experience that optimum success will result through starting with the basics, and then building upon that base. Whichever processor you choose, the evaluation/development kit available for it will be a good investment. If size isn’t too much of an issue, the evaluation board may even wind up as part of your final robot.

(This is not directly related to the Grand Challenge, but I'm not sure who else to ask.)

My question, in short: is there an embedded computer that would be accessible enough for high school students?

Here's the background information:
For the third year, our high school class is designing a robot for the RoboCup Search & Rescue competition. The primary software tasks on the robot involve creating maps of the disaester area and executing low-level autonomy. Our software expectations are significantly lower than the universities participating: we are not trying to implement SLAM, machine vision, or autonomous victim identification.

We would like to integrate readings from encoders, IMUs, proximity sensors, a digital compass, and data from our laser scanner (the Hokuyo URG-04LX.) Our robot also has a thermal imager and several video cameras, however we are not attempting to integrate this data into the software (we may end up simply broadcasting it directly back to the control station.)

Ideally, we would implement a GUI on the control station computer that displays sensor data and video feeds. We would like to use joysticks and a keyboard to control the robot.

I hit the 1500 character limit, but I have more to say. Sorry for the diversion, thanks for your help, and good luck in the Urban Challenge.

Ottawa, Canada October 23 2006 – Unique New Cameras Capture Full 3D Images At High Speed.
LIDAR systems measuring approximately 10,000 ranges/second in a line-scan are commonly available. The AutonoSys lidar video cameras measure ranges 50 times faster, at 500,000 ranges/second. With this amount of data per second, it becomes possible to produce a full 3D image of a scene at video rates of 5-10 frames a second. AutonoSys' camera has a 30° x 90° field of view, with 144 x 480 pixel resolution, updated at 5 frames/second. Range to every pixel in the frame is measured to an accuracy of a few mm. Field of view, resolution and frame rate can all be customized to meet demands of the application. Applications for the new cameras include obstacle and terrain sensing for autonomous ground vehicles, improved recognition of threats in security monitoring systems, and any other application where fast capture of 3D data is required.The lidar video camera uses a rangefinder developed by Z+F Gmbh, a manufacturer with over 20 years experience in the lidar field. The optical scanning mechanism and custom electronics in the camera was developed by AutonoSys Inc., an Ottawa based high tech company specializing in systems and sub-systems for Autonomous Vehicles.

Posted by: Tyler Folsom to Technology:Simulator

The thread on Open Source is quite active. This is in some ways a reply to it, but I started a new thread for increased visibility.

The Urban Challenge is primarily a software challenge. This differs from the 2005 challenge. Since software is the prime component, a driving simulator becomes crucial and is a prime candidate for open source. There is a robot simulator for Urban Search and Rescue (USAR) on Source Forge. This is a mod to Unreal Tournament (UT) and runs on Windows or Linux. I have done a first cut of a driving simulator by modding the USAR simulator. Future plans will incorporate Unwheel, a mod to Unreal Tournament that makes it a driving game. This is not free software since it requires buying one or more copies of the UT game. Other than that, it is potentially open source.

I am team leader for Thunderbird Robotics at University of British Columbia. Making the simulator publicly available will require consensus of the team.

Here is the pseudo-pseudocode for St Louis driving, where only rain snow or ice slows (some of ) the traffic down. They don't let anyone into their lane, yield at yield signs, stop at stop signs, or ever slow down to get behind another vehicle when changing lanes:

If another vehicle detected pulling into my lane: speed up, honk horn, flip off
If stop sign present: ignore
If vehicle ahead stopped at stop sign: honk horn, flip off
If yield sign detected: full speed ahead
If I need to change lanes: no turn signal, speed up to beat any vehicle next to me, change lane
If precipitation
case rain: slow to crawl
case ice:
If (4wd)
drive too fast, spin
Else
slow to crawl

Yah, I've had all kinds of drivers (soccer moms seem to be especially bad here) speed up to cut me off, and even honk when they had to stop behind me at a stop sign. The driving theme seems to be "You had the nerve to use turn signals? !#@$% It's MY road, stay out of my lane! Wait, I want to be in your lane, I'll speed up and just drift over."

Most interesting part:

"DARPA said the change essentially strips its power to dole out prize money. But congressional aides countered that the change actually expands the authority to other defense agencies. Jenness Simler, a committee aide on the House Armed Services Committee, said DARPA can still give out cash prizes as long as it works with its boss.

Pentagon spokesman, Lt. Col. Brian Maka, said the agencies are still working out the details.

"We are not aware of a decision to not award cash prizes," Maka said in a statement""

Frankly, I think the 50k and 100k progress incentives are equally if not more important to the smaller teams. And that would make the contest a little bit more fair.

Posted by: sapper023 to Miscellaneous:Charge 12 volt batteries from 24 volt source

This IS odd but for your humor and my self i could
rewind the alternator 2 of the alternator windings for 12 volt charging ( 15 to 18 volts ) put a big post rectifier capacitor on the remaining only 24 coil left ( diode or ) the rotor winding controll signals from separate regulators inderectly fed through relays controlled by the regulators and use a relay to disable output of the system on what ever branch that did not need charge .
really quick note !
just from parts I have on hand yes I have the 4 additional diodes and relays that can handel 100 amps each
a 12 volt relay and 24 volt relay ( if noise was a problem I could use a chopper type of regulator made from an old wheel chair speed controller )
this would be a verry electricly noisy solution
only small capactor needed on the 12 volt side as it dumps into refrigeration system batteries which can usualy handel noise
the really inportant thing is to manage the batteries properly
kids do not try this stunt at home
of corse now that I have a metal lathe I could just make a custom alternator with 2 alternators on the same shaft and this would be 2 separate charging systems and would be about 20 to 30 percent bigger
you need to sum the electrical watts for proper signal to engine throttle controll which is powerplant system related in difficulty
for engine spin up put a delay on the regulator rotor current and use the regulator signal to engine summed without delay

Congress did vote - the prize money has been cut and trophies will be awarded instead. The updated rules cover this change.

Besides it was Congress not DARPA that made the change and some things are beyond DARPA's control.

I agree it is not as motivating to work for a trophy... on the other hand what a tropy!!!

Charge 12 volt batteries from 24 volt source

Posted by: DaveB to Miscellaneous:Charge 12 volt batteries from 24 volt source

I think that would work fine, even if the regulators for the two alternators aren't exactly matched, so that one bank stays at say 13.5 volts while the other stays at 14. But I'm no expert on battery systems.

Charge 12 volt batteries from 24 volt source

windpower — Mon, 09 Oct 2006 01:36:00 GMT

Posted by: windpower to Miscellaneous:Charge 12 volt batteries from 24 volt source

I was wondering if you could use two 12 volt alternators to charge a 24 volt battery bank via connecting one alternator to the first half of the bank and the second alternator to the second half.

I currently have one 100 amp 12 volt alternator that I got pretty cheap several years ago ($79.00) from J.C. Whiteney and would like to build a wind generator, but would like it to be in the 2500 watt range. So I figured I would need at least a 12 foot diameter blade (I will probably use 15' to offsett resistance due to having to gear it up to 6000 rpm in a 30mph wind) and might be able to use another alternator identical to the first to charge a bank of batteries.

Any suggestions on this plan are welcome......Thanks

SwRI — Thu, 05 Oct 2006 12:42:00 GMT

Posted by: SwRI to Miscellaneous:Potential Urban Challenge Practice Site

Southwest Research Institute (SwRI) in San Antonio, Texas, is exploring the possibility of offering a realistic practice site for use by teams preparing for the Urban Challenge. The site would be available to all Urban Challenge teams on a pre-scheduled basis. The site would support all of the basic and advanced events outlined in the “Rules” and other pertinent documents.

This would be a private undertaking, with no official relationship to DARPA or the Urban Challenge Program. Further, SwRI is not affiliated with any team.

Our intent is to offer use of the practice site at “no-cost” to the UC teams, and to offset our costs by obtaining outside sponsors.

If your team would like more information on this potential Urban Challenge practice site, please send an email to dawn.domaschk@swri.org.

Ivar,

You have a very good point. I, for one, do not care about how much I invested in this so far because I know that my goals are outside of this realm of robotics. This is one of the reason we were pretty open about some of our data and code (http://pegasusbridge.blogspot.com/2005/0 5/how-do-you-drive-by-wire-car-using.html , http://www.pegasus-bridge.com).

Additional to this, there is now an expectation that the track A folks have already laid out their plans in their proposal. Hence any late add-ons of a specific way to interpret data for navigation (new algorithms) is pretty much unavailable to them.

westcoastwatch — Tue, 03 Oct 2006 07:40:00 GMT

Posted by: westcoastwatch to Miscellaneous:Track B Funding?

Assumed prize money authorization was not going to be extended - what are you talking about? DARPA originally announced the competition with a statement about prize money - three main prizes (2 million, 500 thou, and 250 thou plus incentive prizes for Track B participants who were accepted into the NQE ($50,000) and then into the competition itself ($100,000). They attracted 250 people to their workshop in Washington based on these carrots. Then they "announced" at that workshop that there might not be any prizes, but they were working on it. I understand they only learned about the wording in the bill about two days before the workshop. It was stated that the situation would be "resolved" one way or another over the summer. The Track A awardees were supposed to be announced in September - the announcement was made on Oct 2nd. I suspect that part of the delay was due to an attempt to get congressional approval for the prize money. So now without making a formal statement about the change, they simply ignore the original PR, yet they leave it up on their site since it is a mmatter of record. I suggest that there will only be 11 teams entered into the event as it is very difficult to raise sposnsorship support without the incentive of a monetary prize at the end. Those who waited for Track B are out of luck. Those who entered Track A and were not selected are also out of luck.

I don't think anyone assumed prize money authorization was going to be extended (at least we didn't). In fact, we assumed it was non-existent until we heard that authorization would be extended.

DARPA didn't arbitrarily set the event to late October - early November. They knew when funding was going to expire. If authorization was not extended, then DARPA saved themselves $2.75 million.

Regardless, DARPA always reserved the right to change the rules at any point in the competition. Prize money could have disappeared at any time. For that matter, prize money could re-appear at any time also (hypothetically). Or the entire event could be cancelled.

Don't count on the event date to change. There are 11 well funded teams that would complain if their contract/grant were jeopardized by a compressed schedule. 11 DARPA supported teams will have much more influence on DARPA than teams that DARPA did not deem worthy enough for funding.

The interesting point I've noticed is that the removal of prize money was quietly revealed without any mention in today's press release. AP is running a story how 11 teams are competing for prize money. That significant tid-bit wasn't mentioned in the press release.

We have been told categorically that DARPA will not be making any prize money awards to anyone who competes - neither Track A nor Track B. Not sure why anyone who didn't get a DARPA Grant under Track A would want to participate. Furthermore the fact that there are several documents on the site that state there will be prize money appears to me to be contradictory and perhaps illegal. How many people attended the workshop in Washington under the assumption that significant prize money would be awarded?

Seems like a misrepresentation to me!

On slide 10 of the participants conference slides, it says that DARPA's prize authority expires on "September 30, 2007 (End of Fiscal Year 2007)". I think most teams would be willing to give up a month of development time if the race was held on Saturday, September 29, 2007 instead of Nov 3, 2007, if it meant that the race could be held for prizes instead of trophies. That possibility was briefly mentioned at the conference, but, of course, we all assumed the prize authority would be extended.

I do not know that the shape is the important point, but NASA seems to have the clearest description that I found.

http://quest.arc.nasa.gov/space/teachers/ rockets/history.html

However, if you search on the Archytas, everyone seems to have a different description of what he flew. Some say a clay pigeon. NASA in particular indicates a wooden pigeon. One said it was probably a kite (though that site seems alone in that opinion). Most do say it was steam powered and and flew on a suspended wire (i.e. it propelled itself, but did not actually fly in the conventional sense) and could fly several hundred yards. But I do not think anyone actually knows what it looked like as the description comes from an author 300 years after the event.

I do not know that that gives you any more then you already had, but good luck.

They are all very scholarly and interesting but they mostly contain

I would direct you to our own website, but the chargers we make are for military applications only – quite expensive and not usually available in lots of less than 10. You might consider using a multi-winding dual-voltage alternator like those made by MBP, or even a 24V input inverter, like a Dimensions Unlimited model, running a 12V 3-state charger. Dimensions even makes models with smart chargers built-in - I'll bet they would be willing to build you a 24V model, with a 12V charger wired up to the inverter output.

Trevor - How far did KNetX get with the buggy design? The last time I checked into their stuff, they were still running the pickup under the team name Rjunkworks - and the buggy was at Sandstormers' previous location, getting painted. I had planned to visit their shop - but got involved with a different entry, and wanted to avoid any conflict of interest.

Charge 12 volt batteries from 24 volt source

Jassper — Wed, 30 Aug 2006 09:14:00 GMT

Posted by: Jassper to Miscellaneous:Charge 12 volt batteries from 24 volt source

Militoy - Thanks for the heads up, but I already know that and I have taken it into account. Right now I just need to know if it is possible to use the 24volt alt to charge the 12volt batteries. You speak of a 3 stage charger that can take the 24volt input and charge at 12volt. Can you provide a link? This type of charger I have not been able to find - or I'm looking in the wrong places.

The "cartoon" is just a simplified diagram of the system. The currect 24volt system is regulated by a 3 stag alternator regulator, If I can use the same alternator to charge the AGMs without effecting the current system, then I would use appropriate means to protect the AGMs.

Thanks

I haven’t had a chance to look over the cartoon of your system, but here are a few notes on your charging issue:
AGM batteries need to be charged using a different set of current/voltage/temperature parameters than flooded lead-acid or gel cells. Simply bulk charging them like you might a flooded lead-acid bank can cause AGM batteries to explode under certain (unfortunate) circumstances. Charging cycles should be controlled in accordance with the battery manufacturer’s recommendations. The safest way to charge AGMs, and to assure their long life, is to use a 3 or 4-state charger, with temperature monitoring of your battery bank. The charger should be set up for "undercharge", "bulk charge", "overcharge" (optional), and "float charge". Look for a 3 or 4-state 12V charger that’s programmable for AGMs, and set up to run off of 24V. There should be commercial versions available (ours are for military applications, and fairly expensive). You will save $ if you undersize the charger capacity a bit, and put up with a slower charge rate.

Thoughts

The alternator must charge the batteries while delivering full load

Charging load might be eliminated by precharging batteries,
but then why would you need such large batteries?

200 A of 12 V uses only abt 100 A from the 24 V system

24 V equipment is smaller, & uses smaller wires than 12 V (1/2 the amps)
Could you change any of your load to 24 V?

The only reason for separate batteries is usually to reserve power
to start the motor -- a battery that won't be drained by "hotel" load.

It's a bad idea, for battery life, to charge at more than half its capacity.
That is, don't charge a 100 A Hr battery at more than 50 A

Complicated battery networks can make the above difficult to prevent.

If you're sure the alternator is 270 A at 24 V, it's probably plenty big enough,
but if it were actually 12 V, and used the equalizer to power the 24 V, then maybe not.

Equalizers, like inverters, use electronics that fail if overloaded, and sometimes if not,
so a more reliable system may be to add a 12 V alternator, and simplify the battery network

You could upload that schematic by clicking the "Attach File" button at the top of the window,
or just describe it, e.g. "24 V alternator to two batteries in series. 24-12 V equalizer from 24 V
to two batteries in parallel. 20 A of 24 V load. 50 A of 12 V load.

Why DO you need such large batteries?

Posted by: Jassper to Miscellaneous:Charge 12 volt batteries from 24 volt source

We are adding (6) 12 volt 8D AGM type batteries rated at 255 Ahr for a total of 1530 Amp hours. The main charging will be from two 2500 watt inverter/chargers each capable of charging at 125 amps. Why so much power? Because our clientele does not know the meaning of "power conservation". They expect to be able to run everything regardless if they are driving, plugged into shore, or dry camping. My main concern is the fact that one of the (3) 1500btu air conditioners can be used while driving. The Air conditioner pulls about 18 amps AC while cooling. This equates to 180 amps DC at a 10:1 ratio out of the inverters. I realize not much charge will actually be going into the batteries and we will be using a Drop out relay to disconnect the Air Conditioner if the battery voltage becomes to low. The Inverters are also backed up by a 20Kwh diesel generator, if the power consumption is above a set point for an extended time the generator automatically starts – IF the customer has turned that feature on. Why the customers won't use the generator to run all 3 airs while driving is beyond my understanding of the rice and famous.

I don't have the schematics with me. I will get them on Monday and attach them along with other specifications and show what we want to do to the system. I have attached a simple drawing of the basic configuration. I'll post more info tomorrow. Thanks again

A rough note sorry if I skip around on subjects .
This is a common upgrade problem of recreational vehical , vehical computer instalation , large robot desighns ( mine at least ) and car sterio power systems and your proposed idea may work in a few situations but may be troublsome if the system is not understood before upgrade so you are wise to ask around .
Without a schimatic of your system and proposed system I would hesitate to comment as there are several issues of charging system style , safety , economy and practicality .
I also would not load an alternator more if the power plant was desighned to have that alternator as there is a general mechanic practice of using large alternators to offset heat and peak load requirements issues and may need a wider belt or more belts and/or cooling and/or external diodes to actualy deliver full ratings .
If you do not want me to evaluate your system take your system to a recreational vehical or industrial truck wiring specialist and request quotes or information on your alternatives , as there are manual and automatic systems to choose from as well as lifespan and matinance issues they could also see if there will be belt and heat issues as it could take me a month to find my reference material on belts and pullies .
Could you provide a schematic of your system as I may only need a paragraph for response for the electrical issues .

Posted by: Jassper to Miscellaneous:Charge 12 volt batteries from 24 volt source

Not really related to the Grand Challenge, but who better to ask than you guys!

Situation:
I have a 24 volt 270amp Delco alternator driven by a series 60 diesel engine. Now it is connected to the chassis system which is a 24 volt system, Four 12volt batteries wired in series-parallel for a 24volt bank using a 100amp Equalizer. The chassis system only requires about 60 to 70 amps, leaving me with about 200 amps unused. I have a second "House" system of Six 8D 12 volt AGM batteries wired in parallel, this system could demand up to 200 amps +.

Question:
I've never seen this done, but - Can I use the 24 volt alternator to charge the 12 volt batteries? I know the equalizer already splits it into 12 and 24 to charge the chassis batteries, would changing the 100 amp Equalizer to a 300 amp allow me to tap off the 12volt side to charge the house batteries? The House would be a much larger draw so I'm thinking that this would over load the chassis batteries.

Is there a way I can take advantage of this over size 24 volt alternator to charge a bank of 12 volt batteries?

Thanks

Being street-legal isn't enough because this is a race. Moreover, it is like a race driven by chimps. Race vehicles are often expected to have additional safety measures, and DARPA is correct in requiring the same here. I can see why they are interested in non-chassis upgrades. For instance, Red Team's H1ghlander used a custom hydraulic steering system. Hydraulic steering is now used in some trucks but is illegal in several states. Electric drivetrains, hydraulic steering, and custom fuel tanks all could make the drive-by-wire problem easier, but introduce new safety issues. Ideally DARPA would let teams make any modifications then perform a safety inspection, but DARPA doesn't have the expertise for that.

In a real world scenario your product might be of use, but for this competiton in a "simulated urban environment" I think the route files must be followed.
The rules specify that route files (plus any data which can be derived from supplied maps etc) will be used, ie, existing signage may or not match the route files but the route files trump existing signage / street markings etc. This gives DARPA the flexibility to create their "simulated urban environment" on an existing training site or similar without having to have any signage present at all.

Who has a team in the DARPA Little Dog competition?

Posted by: John Nagle to Miscellaneous:Who has a team in the DARPA Little Dog competition?

This isn't DARPA's only robotics competition. There's also the "Little Dog" program for
legged robots. (BAA 05-25) Anyone involved with that from a non-university organization?
I know which universities are involved already. Thanks.

We seem to have had a better experience with our Sicks than many other teams did.

Track B Funding?

Posted by: LeenSTL to Miscellaneous:Track B Funding?

It was for all funding of prize monies, correct? AFAIK, it affects the winners regardless of the their track, ie, the race might turn out to not have any cash payout to the winners. That is my recollection of what was said by Dr Tether in the conference, there is a transcript online that you can peruse.

A harder course.

I would be very surprised if someone wins the Urban Challenge with Sicks. Their limited range and wacky behavior, along with the most overly-complicated API I have every seen, all contribute to making them a poor choice for any autonomous vehicle application, especially one as difficult as the Urban Challenge. This is just my two cents. We used them last year, and we finished the race, but using them was like pulling teeth.

A harder course.

JN: But you're not going to win the Urban Challenge with SICK units. It's time to move up.

I respectfully disagree with John.

Some people said that SICK units were not good enough for the Grand Challenge, but in fact, they were perfectly adequate, as Stanford demonstrated.

SICK units should be even more adequate for the Urban Challenge, with its lower speed limit and mostly-paved environment. In my opinion, the Urban Challenge is not harder, at least not much harder, with respect to sensing. It is much harder with respect to planning. It will be won by the best planner, not necessarily by the best sensor.

We had on-board cameras, but to our great regret, we did not recover any video from the GCE event. We have ladar images, up to the point where the computer crashed.

Our vehicle was doing very well, on pace to potentially win the race, until we unexpectedly ran out of memory at twenty-two miles. A more detailed write-up is here:

Our chase driver said that the robot bouncing over the desert at sixty miles per hour was a remarkable sight. He was also disappointed that we did not get any video.

Track B Funding?

Steve — Mon, 10 Jul 2006 07:29:00 GMT

Posted by: Steve to Miscellaneous:Track B Funding?

I do not know the details of what is going on with this (and I would appreciate updates from DARPA when they have some), but as I have had similar questions I can add this.

1) What was said at the conference (if I remember correctly) was that they MAY have resolved things by the 4th of July.

2) Searching the Senate calender, it appears that starting on the 20th, the Senate is going to start (it is scheduled for at least two days) to vote on amendments to the Defense Appropriations Bill to try to resolve the differences with the House Bill.

3) When I search the House Bill, I cannot (I am not an expert on such things) find anything to do with this event -- but I assume it is buried in there somewhere (perhaps as an attachment).

4) The Congressional appropriations cycle is a long one.

I do not know if this helps, but it is what I could search out.

Wasn’t there something that was going to be voted on by congress
about track B funding? If I remember correctly the vote was supposed to have
happened by now. I have looked everywhere trying to find what might have happened
and have not been able to locate anything about it. Does anyone know the status
of it?

Yes, Stanley was a VW, but a Touareg rather than a Golf. Maybe Stanford will start with that Golf, this time. Its top speed wouldn't help, but starting with built-in sensors would be cool.

I wish they had a video of that Golf going 150, rather than about 5 mph.

Indiana (hopefully, central)

Flutter Vertigo — Fri, 07 Jul 2006 07:25:00 GMT

Posted by: Flutter Vertigo to Teaming:Indiana (hopefully, central)

I'm in Fishers (just over the NE boundary of Indianapolis).

I was recruited to work on the '05 race led by Scott Jones and Doug Traster. (If you know where Scott's estate is and where to look with Maps.Google, you can still see the jeep's tracks, particularly when the map data has Winter images)

I'm in my mid-40s, so I've got considerable experience in a lot of areas. I also won't be bound to a different schedule when school goes into session, including the fact we have no kids.

When working on the IRV project, we were generally expected to work a minimum of twenty hours per week, but the "Yellow House" (it was a rather large, multi-story yellow house on the corner of Scott's estate) was generally full of people every night of the week as people would hang out there instead of playing games or coding other things at home. i.e., there was a lot of dedication to the project.

Thanks,

phil

Trevor, I've had the same problem with the spaces in URL's. One way to get around it is to highlight a word
in your text then click on the "Create Link" tool, then paste the URL in the popup.
I did that for your link here.

This would be a great car for some team to enter the Urban Challenge with! Was Stanley a VW also?

PS
- I can not get the little space out of the URL that is between the "n"

Very cool, did you use the same type of waypoint following from the 2005 GC? How will the actual event be run, ie, will there be multiple bots on the course at the same time? Or will it be more like the 2005 GC where each bot is launched separately?

Did your vehicle slide around the curves like this? http://www.youtube.com/watch?v=_oywkOzRug Y&mode=related&search=
