$2 Million on the Table for DARPA Urban Challenge

Posted by Zonk on from the go-robo-racer-go dept.

coondoggie writes "The contestants: Thirty-five driverless vehicles. The goal: to navigate an intricate faux-urban environment quickly. The prize: $2 million for the fastest qualifying vehicle. 'The National Qualification Event will take place this weekend ... DARPA says its third-annual Urban Challenge program has the lofty goal of developing technology that will keep soldiers off the battlefield and out of harm's way. The Urban Challenge features autonomous ground vehicles maneuvering in a mock city environment, executing simulated military supply missions while merging into moving traffic, navigating traffic circles, negotiating busy intersections, and avoiding obstacles.'" I'll be cheering, as long as the creepy robot bear isn't participating.

    We already have that. It's called congress. It's just broken right now.

      Most people these days don't understand the difference between Pedophilia and Ephebophila. http://en.wikipedia.org/wiki/Ephebophilia One is unnatural (doesn't make sense biologically), the other is simply culturally unacceptable. Back in the days when the average life expectancy was 40 years old, it made a lot of sense to marry a 14 year old. These days it makes more sense to have young teens continue their education and social development, consequentially our cultural perceptions of what is acceptable have changed.

  2. Is a good thing the are working on this by Anonymous Coward · · Score: 4, Funny

    Because the wars of the future will not be fought on the battlefield or at sea. They will be fought in space, or possibly on top of a very tall mountain. In either case, most of the actual fighting will be done by small robots. And their duty is clear: To build and maintain those robots.

    Screw cars that will parallel park themselves, if they can make cars that navigate those abominations that are Traffic Circles, I'd buy THAT!

    God but I love technology! The old WWII vets are all worried about losing their mobility when the state determnes they're no longer fit to drive. By the time I'm that old (and I have gray hair and a white beard already) I'll have Sally.

    Military implications? Pshaw, I want my car to drive me home when I'm too drunk to drive myself!

  5. What about... by Lifyre · · Score: 5, Interesting

    Caveat I haven't had a chance to read the entire challenge to see if it answers this question. I'm in Iraq I have better things to do, sort of...

    Does the vehicle have to be one piece? Specifically can it launch a UAV to provide a top down view of the street? This could be then used to avoid crowds (or head towards them), get around dead ends, and generally navigate the cities. The imagery we have is often horribly out of date and roads have moved, stopped existing, or new ones have popped up.

    I think having an eye in the sky dedicated to the vehicle could be a tremendous asset.

      Yes. All of the equipment has to be on the vehicle. As far as communication goes: GPS is allowed, and a remote kill switch is allowed (required, actually). Other than that, everything is on board. Typical fare is regular cameras (which have good distance vision, but require some smart computer vision algorithms) combined with laser range finders. The winner of the last DARPA challenge was a robot named Stanley (from Stanford) who mapped laser range finding data onto the video images, thus identifying the safe path in the image to travel through.

  6. We've got these here by PPH · · Score: 4, Funny
    In my town we have quire a few vehicles, mainly large Cadillacs, that cruise the streets with no apparent driver. They still have some bugs to work out, as they don't always stop for signals or pedestrians. And they definitely don't move very quickly.

    Upon closer inspection, one can see a little grey head not quite level with the dashboard. But I don't think these occupants have any connection to the vehicles' control.

  7. The hardware is much better than last time by Animats · · Score: 4, Interesting

    One of the major side effects of the DARPA Grand Challenge series is that the supporting hardware has become much better. You can now buy most of the major components off the shelf. GPS/INS/compass/odometer navigation units are a few thousand dollars, rugged, and work well. When the first Grand Challenge was announced, the off-the-shelf solution cost about $170K and required 4U of rackmount space, with air conditioning. CMU actually used that in the first round.

    LIDAR units have improved enormously in the last two years. Last time around, everybody just had single-beam line scanner LIDARs, usually from SICK, except for Team DAD, who built a multibeam scanner that worked but wasn't rugged enough. This time, the major players have multibeam LIDAR units from Velodyne or Ibeo. Velodyne's unit has 64 lasers on a spinning drum. Now you can image your entire environment in 3D at 5Hz.

    Controlling the vehicle is easier, too. There are now cars available with electrical power steering and brakes, and one can tap into those systems to drive. And there are at least three vendors selling gear for remote/autonomous driving of existing cars.

    So now it's almost entirely a software problem. You don't burn so much time and effort building sensor and actuator systems.
