DARPA Grand Challenge Updates 156

Posted by Zonk from the good-luck-folks dept.
Red Team writes "Today is the day. The official race route for the DARPA Grand Challenge was released to the first five teams at 4:00AM PST this morning. Our race planners are pouring over the race route getting ready for the launch. H1ghlander will start first at sunrise, around 6:15AM PST, followed by Stanford and then Sandstorm. For real-time updates on the race, you can track the Red Team race-day blog or catch the webcast on the official Grand Challenge page." Update: 10/08 20:57 GMT by Z : USSJoin writes "Stanford Racing, home of Stanley, has just finished the 131.2 mile DARPA Grand Challenge course. Considering that the CalTech Vehicle (Alice) jumped off the track toward onlookers only 8.3 miles in, this demolition derby-meets-AI demo has certainly been exciting."

      Every team has managed to make it past the point traveled last year - except for one. The MITRE Meterorites, who in one hours and seven minutes traveled a total of 0 miles. I'll bet you they can at least double that next year. :) I have to wonder how they managed to qualify for this round if they weren't even able to leave the starting line.

        Cite? MITRE [wikipedia.org] didn't exist when the final US battleship [wikipedia.org] was built, nor did MIT Lincoln Labs [wikipedia.org]. I suppose the MIT Radiation Laboratory [wikipedia.org] was contemporaneous in 1944, but I expect their expertise in OS recommendations was limited. I suppose this lack of knowledge of operating systems is excusable as there weren't any operating systems.

        Oh, you mean the USS Yorktown [wikipedia.org]? That's a guided missile cruiser, and back in the old days the hull would have been called a destroyer, before the Navy decided to change the nomenclature. Little bit of a difference between a destroyer hull and a battleship, but hey, AC abuse is par for the course.

        As much I relish the image of some poor ensign yelling, "Screen's blue, SIR!", nobody seems to think this was an OS-level crash. [ncl.ac.uk] And most of the google hits I can find on "navy smart ship mitre" point to things like Think Outside The COTS [mainframemigration.org]. Scrolling down to Figure 1, there's a list of potential pitfalls of commercial-off-the-shelf software.

    • I have not seen robots managing with ease and RELIABILITY even mildly unstructured portions of the world. I wouldn't trust a 3 ton vehicle to the Mars Pathfinder's 'brains', for example.
      Also, there are cost issues. Manned supply lines could be safer if you invested money (armour, more soldiers, aerial support, etc.), and maybe it is less than the cost of having an autonomous fleet of vehicles that will not be 'fool' proof.

    • That won't work.

      If you automate the supply convoys, none of your supplies will ever be delivered because every one of those convoys will be destroyed. Why? because the enemy has no incentive to NOT attack them. They can blow up driver-less robot trucks all day long and they know that nobody in the convoy is gonna do a damn thing about it.

      As a team leader of one of the teams eliminated at the NQE [overbot.com], I didn't see any visible favoritism by the DARPA staff. The teams that went to Primm are the teams that should have gone.

      Funding is more of an issue. Teams were supposed to have no Government funding whatsoever, either direct or indirect. Yet MITRE had a team, and they're a quasi-governmental agency. [nara.gov] CMU has received DARPA robotics contracts for years, as has Stanford. Red Whittaker of the CMU team is still the principal investigator on a NASA grant (#NAG5-12890) until February 2006. Stanford used software developed under DoD contract, although anyone can download it and they asked DARPA for permission. It's more of a revolving-door issue than direct diversion of Government funds.

      But the real incentive for the big university teams was fear. If Joe's Auto Parts fielded a better robot than some university getting $20 million a year in robotics funding from DARPA, DARPA might well pull the plug on the school. CMU faced that prospect; originally, they weren't going to enter the Grand Challenge at all. The whole Grand Challenge was created because of unhappiness at DARPA with the rate of progress in mobile robotics. DARPA has been pouring robotics money into CMU and Stanford for thirty years, without getting much back. The head of DARPA, Dr. Tony Tether, decided that it was time to do something about that. It worked.

            • Actually a lot of the no-bid contract talks these days is in reference to all the cronyism going on down south in the wake of Katrina and Rita. Billions and billions of dollars in contracts were awarded without bid or even research. Many of those contracts are being reevaluated and put out for bid, but only after much fuss was raised in the media and Congress.
            • Lets say the government decides to build a $300,000,000 attack blimp. They open up competition to all of the local businesses which will of course bring sorely needed jobs to the local economy. Everybody votes for it, nobody asks if it's necessary. So I guess you're right, my beef is with necessity but it's good to know there are rules in place to prevent cronyism.
    • If there is anyway for Cheney to profit from the red team, I will belive you.

    • You think the red team has major military sponsors? Look at Team Terramax. Their vehicle is from Oshkosh, the largest supplier of military trucks, and is widely in use by the military. The team's navigational system came from Rockwell Collins, another colossal military contractor. I'd say that Terramax's military ties is stronger than any other team.
