DARPA Grand Challenge Teams Submit Videos to DARPA 93

doughnuthole writes "The deadline for DARPA Grand Challenge teams to submit their videos to DARPA just passed and some have posted them online. Some of the teams with these videos posted are Team Caltech, Axion Racing, Virginia Tech (on the Media page), Insight Racing, and UMass Dartmouth. The Grand Challenge is a 175 mile race run by fully autonomous vehicles. Since no teams completed the 2004 race, DARPA decided to run it again, this time for $2 million."

      Last year teams had such a short period of time, it was difficult to write all the necessary software and spend the time necessary to test and refine. Now many teams have learned a lot from the previous race and have much more time to improve. Several are now able to drive fully-autonomously at speeds of up to 20 mps while still avoiding obsticles and following a path. The maximum speeds will continue to increase and bugs will continue to be routed out as teams gear up for the race.

      Most teams are not in it for the money, but for the sake of science and engineering. Some teams will spend close to that amount before all is said and done.

      I had hopes for the DAD team. They have a simple and robust sensor suite.

      Their problem was they had to halt their vehicle to allow the officials to tow one of the challengers out of the way. And when they restarted, their front wheel was stuck on a rock. Their software wasn't smart enough to gun it and get over that small obstacle. Must have been frustrating not to be able to kick that damn rock out of the way. Up to then they were looking good.

  • If we can't make a land based car that will drive it self, how much longer do I have to wait for my flying car then?

    Seriously, I've put a good deal of thought into this, and it should be fairly simple to engineer a system that would drive your car during times that it would be appropriate to use a cruse control.
    • they have systems like this, it uses metal rods embedded in the road and sensors on the car to figure out where exactly in the lane it is.

      The problem is figuring out when it needs to leave cruise control and slow down, speed up, avoid collisions, turn, etc. You know, the 99% of the time when you aren't on a straight, flat, open road with no traffic.
      • why is that a problem? use a simple graphics system to determine needed things, like other vehicles, edge of road, lanes, etc. use laser or radar to determin relative speed to other vehvicles. Simple modifications to the car for steering and speed control. I imagine I could do this for under $5k with off the shelf materials, and I'm not even a real engineer.

        like I said, considerable thought.
        • If you were a real engineer, you'd know it isn't that easy. How do you determine another car in front of you? Shape, color? Computers are NOT good at doing graphical pattern matching. Its non-trivial to recognize slow moving identical objects, much less fast moving objects of widely differing shapes and sizes (like a sedan and a big rig).

          Detect lane edges? How? You can't assume special equipment in the road to tell you, it doesn't exist yet (and could fail if it did). Look for patches of white lines
          • Okay, so I didn't say it was easy, it isn't trivial, but maybe that's the problem with "real engineers" is that the solution has become far more complex than it needs to be. Us engineering tech types (kind of like real engineers but get paid less) like to keep things simple.

            Let's look at how us human types drive. We basically determine what is road and non-road. More specifically, what is our lane and what is not-our lane. We keep our speed at the speed limit (in theory). We don't hit anything directl

        Different problems, and they require different solutions, and a system that could pass the DARPA test would be overkill and unsuitable for the daily commute to work.


        I suppose that depends on what one considers a combat zone; dealing with "drivers" who are busy eating a bagel, reading the paper, drinking coffee, talking on a cell phone, shaving, and putting on makeup might require a combat-ready system.

      I think the big problem is one of cost and transisition. The most obvious solution is that the road and car talk to each other. However, this would mean that just upgrading the largest highways would be very expensive and take a long time. This would mean that there would be little benefit to those who own cars that are equipped with the ability to drive itself. A guess this is the whole chicken and egg problem.

      The other issue is what to do about oder cars not so equipped. In addition to the road and car t

    Interesting that the DARPA Challenge rule precludes hovercrafts from competing as they do not primarily use traction with the ground for propulsion.

    I hope a team enters with a very large metal hollow sphere with gear teethmarks lining the inside and the machinery be a shaft, gyroscope and gears on both ends of unequal weight. The rest of the contents can be fuel/energy cells to power the rotating motion of the machinery inside -- it essentially just has to "throw" itself in a direction and keep rolling and steering. Travelling 175 miles ought to be possible as long as the terrain isn't ridiculous.

    As is well known in all film car chases, vehicles have a higher chance of survival (especially when wrecked beyond usual driveability) if they are being chased.

    A load of drone cars should be driven behind these competitors with models of druglords with machine guns, outlaws, corrupt police officers, and people to whom the teams own money.

    That way, they should be able to defy gravity enough to land from a great height at a mere 30 degrees to the horizontal without breaking their suspension or driveshafts, and continue to turn even after front side collisions which would leave bushes and pinions bent (or wheels set to cambers which would normally cause them to no longer turn). They might even get speed boosts beyond the maximum engineering speed expected for the motor, gas and gearbox actually installed.

    For an added bonus, they could have critically wounded people in the back, and an accomplice who absolutely has to jump out at 40mph somewhere mid course in order to continue some secret mission.

    Our Team Overbot video [overbot.com] is on line.

    One of our biggest problems in Silicon Valley has been finding a big open space in which to test. We now have access to a huge parking lot built during the dot-com boom, adjacent to an unfinished building complex. So we have the Overbot winding in and out among the parking islands. We'll be testing there today in a few hours.

    In terms of technology, Team DAD [digitalautodrive.com] probably is most innnovative. Everything runs on digital signal processors. They're building their own laser rangefinder this year. Last year, they got further than anybody else without wrecking. (CMU crashed three times; their HUMMV was able to survive the first two.)

    Nobody seems to have a breakthrough in sensing. (By this I mean sensing good enough to evaluate terrain. Detecting big, solid obstacles is trivial.) LIDAR line scanners are too limited, stereo vision doesn't register well on dirt, and strong intelligent vision processing requires a breakthrough that twenty years of research has failed to produce. The breakthrough needed is flash LIDAR, which exists, but wasn't ready soon enough for this year's Grand Challenge. (The rules prohibit the use of Government-funded patented technology not available for general sale by last August, and the good flash LIDAR wasn't available in time.) CMU has a LIDAR line scanner on a giant gimbal, and we have a LIDAR line scanner on an overly large tilt head, but that's an interim solution and a technical dead end.

    On the other hand, GPS and inertial gear gets better and cheaper every year. It's surprising how good it is.

    This year, everybody who makes it to the starting line should disappear over the horizon at the start. The minimal level of performance to make it through the "site visit" hurdle is above that demonstrated by most of the vehicles entered last year.

    And this year, DARPA is putting tank traps on the course.
