DARPA Grand Challenge A Real Race At Last? 173

museumpeace writes "News.com has posted its second story in a week on a hopeful Grand Challenge contender. Stanford's Stanley, a VW Touareg run by 100,000 lines of code can hit 40 mph and has now traversed all but 3 miles of last year's desert course without problems. A few days earlier, Carnegie Mellon University's Team Red announced that its Sandstorm, a modified Hummer, had run 200 miles without any problems though on a closed track. DARPA cut the field to 40 in June and will cut it to 20 before the race in October."

And while conquering basic controls problems including obstacle avoidance, I think the real problem as usual will be obstacle detection, not obstacle avoidance.

    • Actually... the way the article phrased it:

      The computer scientists have written more than 100,000 lines of code to tell Stanley what to do.

      Made it sound like the journalistas thought that was a *lot* of code. I was just thinking that didn't sound like much at all, given the team-size and project scope. Maybe 10,000,000 or 100,000,000 would be a lot. 100,000? That's about a typical mid-sized software project. (Depending on the environment of course)

      What does it mean when someone says they ran "last year's course" without a problem?
      Does the car take to the road knowing nothing of the obstacles ahead or has it been programmed to avoid the hazards revealed in a year's study of the route?

      • in order to make it to the qualifying round, your vehicle must show path following abilities and obstacle avoidance. the darpa guys tested this during the site visits by placing some obstacles on the way points (gps coordinates) and some near way points. so, to answer your question: it should handle arbitrary, unknown obstacles. that said, they may well incorporate a priori knowledge of the course into their control.

      I don't think you're paranoid -- I think you're ignorant.

      Last I looked, the ratio of support personnel to fighting personnel was something like 7:1 in the modern military. That means that for every person whose primary job is actually killing people, there are seven people whose primary job involves support functions. One of the big support functions is "get this stuff from point A to point B."

      While sometimes "get supplies from point A to point B" can be rather hazardous -- our supply units in Iraq can talk about that -- it can also quite often be boring, repetitive, and relatively safe. Being able to send supplies to the front lines without having to equip a truck with people will help alleviate this need.

      The DoD spends many billions of dollars on research every year. The really sexy research -- "how do we kill people better, faster, and in more bulk?" -- gets the most coverage, but a very significant chunk of their research is around things that are not directly related to the whole "kill or be kill" thing -- for example, the internet.

    20? What are the elimination criteria for the vehicles DARPA's simply not going to let compete?

    Specifically, if no one has ever done this successfully before, how the heck do they know what a successful approach looks like?

    I understand dropping the obvious non-starters - teams whose vehicles crash or get lost on a small test course, or teams whose vehicles are not ready to go at all - both of these are valid rejection criteria.

    But it seems really silly to set an abitrary number at "exactly 20"; the article doesn't really explain how the decision on whether or not your vehicle "makes the cut", other than "was evaluated by DARPA experts" - who have yet to solve the problem themselves.

      The principle challenge here is effective navigation of difficult terrain. The Mars rovers are extremely slow, manually driven, (albeit by extreme time delay), and it takes a *lot* of skilled people to keep one going. If autonomous vehicle technology is significantly improved, then the effect on the the mars exploration program would be vast. And actually the desert scenario is pretty close to the problems found on mars: Sandstorms rocks sand more sand holes Imagine Mars being explored with ten (or more) completelly autonomous and robust vehicles scooting around looking for interesting features. That would rock.
    • The Caltech Team is reasonably close to various people at JPL and as such they were all set to give us their code, but DARPA told us we couldn't use it (no big surprise there). It's not really a big deal since it's a better learning experience for our team to develop the code themselves.

      On a separate note, I believe that our vehicle is the only one that can fit a reasonable number of people inside, comfortably, with seatbelts (6 I think).

      • That's because you choose a huge ass SUV for your vehicle. Obviously people with smaller vehicles will have less seating. The MITRE Meteor for instance only seats two because it's a Ford Ranger.
        • I suppose I should clarify. Yes there are teams that chose small vehicles but there are plenty of other teams who chose large SUVs (a certain H2 comes to mind) and still have little seating space. I'd be damned impressed if you managed to have 4-5 seats in your Ford Ranger after installing a bunch of computers and onboard sensors.

    Good article about the Stanford and Cyberrider teams, with video.

    The project is based on a partnership of several companies. Volkswagen provides the vehicle, a diesel-based Touareg R5 TDI with an automatic transmission, and the automotive know-how. Intel is supplying the Pentium-M chips (Dothan core) as well as the platform consisting of several 855GM-based mini-ATX boards. Then there is MDV (Mohr Davidow), a company that invests in start-up firms. Android, Honeywell, Tyzx and Coverity are among the other sponsors. Tyzx has specialized in image recognition software, which is especially important for AI (artificial intelligence) systems.

    It goes without saying that the power hungry P4 processors and the corresponding platform would have made a bad choice. After all, the power dissipation loss of these seven systems would easily have exceeded 1200 Watts! This would have required special modifications to be made to the alternator and several other components. Instead, Intel has supplied the project with its tried and tested Pentium M notebook processors. These use the Dothan core with its 2MB of cache, are clocked at 1.6GHz and run on an 855GM platform. As a result, the overall power requirements of all seven systems together are only 280 Watts. The individual nodes are linked using a Gigabit Ethernet network.
