tonyquan writes "DARPA has just announced that Stanford's "Stanley" autonomous ground vehicle has won the Grand Challenge, a $2 million contest for driverless vehicles over a 132 mile course in California's Mohave Desert. Stanley's winning time over the course was 6 hours, 53 minutes and 58 seconds, for an average speed of 19.1 mph. Second was Carnegie Mellon's Sandstorm (7:04:50), third went to another CMU vehicle "H1ghlander" (7:14:00) and fourth to the Gray Team's KAT-5 (7:30:16) More info from DARPA."

      I don't think it shows a great advance in robotics and A.I. (although that is partly responsible), more just an advance in how they handled the DARPA Grand Challenge. If DARPA gave them a different challenge of similar difficulty, it might take them a few years to finish again.

        It's not so much an improvement in the AI as it is an improvement in the sensors. These vehicles look ahead about 30 feet and plot their course based on very simple logic. If there is a negative obstacle (a hole), it is more difficult for sensors to detect than if there is a rock sticking up in the path. Last race, the only thing that stopped red team was a hairpin turn. Their sensors looked straight ahead and only a little to the sides, but when faced with the hairpin turn, the vehicle almost fell off the side of the mountain! But the rules of the AI haven't changed much- just the sensors. If you're driving through jungle, for example, you have to have sensors that don't see leaves as obstacles. Otherwise the path will look totally impassable.
        • Luckily, there are very few trees on Mars! One of the stated objectives of the DARPA Grand Challenge was to contributed to unmanned missions to Mars, etc. The main reason for having a totally autonomous system (as opposed to one that responds to remote control) is for when the lag time for remote control is too large.

          Granted, the tree observation does potentially limit Terran deployments.

            Actually, planetary rovers are just a tiny, tiny portion of the reason for this challenge, otherwise NASA would be sponsoring this, not DARPA. The primary reason for this challenge is for troop supply and support vehicles that can accompany troops into a battlefield, or be sent in autonomously. Which means the jungle scenario is non-trivial. One of the reasons the challenge is being held where it is, is due to the development lifetime projected force deployments being in mainly desert regions. Another major projected use for these kinds of vehicles is for deployment in a bio-hazardous area for testing and sampling in an autonomous measure. But once again, the is a DARPA challenge, not a CDC one.

      There are several factors here. First and formost, the vehicles are more capable. The software is vastly better and the hardware is somewhat improved. Did you think that they've been sitting around doing nothing for the past 17 months? They've been working on improvements since the last challenge, and they've spent a lot more time actually testing their vehicles in desert terrain.

      There are some people who say that this year's course is far easier than last year's. I don't know myself -- I'm not involved with any of the teams and I don't have detailed knowledge of the courses. But there has been some commentary by those involved to this effect, as well as from bystanders. One huge difference is that the most difficult part of the course (Beer Bottle Pass, a narrow road with a steep drop off on one side) was at the end of the course this year, while the equivalent part was near the start last year. Stanford's leader is quoted as saying something to the effect that if they'd inverted last year's course then a lot of cars would've gone much further, even if none of them finished. The complete lack of media attention last year may have been one reason why DARPA swapped the course around -- it's rather anti-climactic to write about a race where the best racer hardly even got off the finish line and leads to the kind of stories DARPA really doesn't want to see (waste of taxpayer money, will never work, etc.).

      In any case, given that less than 25% of the vehicles finished, I'd hardly say that it was a trivial thing to do. It's still amazing. Congrats to those who did, and to all of those who participated for that matter -- it's quite an accomplishment, even if there's a long way to go still before this is really usable in a real world environment.
      • The interview with the Stanford team lead also said that last year, there was talk of the course being much harder and 300 miles long, so teams over-engineered their vehicles. This year they had a much better idea of what the course would be like, so they could spend their time better.

        It should also be mentioned that at least the Stanford team and the CMU team claim to have completed the old course while preparing for this year's event. So even if this year's course is easier, there are some teams that completed the old course anyhow. Obviously this wasn't under race conditions (the most important condition being that you don't know the course until just before the race) but it is still relevant.

        They blew a tire and were somewhere around 60 feet off course when they were eliminated, if I remember correctly.

        I know that a good number of the teams were actually still moving when they were eliminated; they had generally just wandered far enough off course that it was determined that they would be unable to finish.

        There were a number of reasons why people did so much better this year than last year.

        The biggest reason I think is that people knew a little better what to expect this year, and focused development on more important items for the race. For instance, for the first race I had done work on using a terrain database for path planning, but it turned out that the waypoints are so close together that it ends up just being a waste of CPU cycles for the most part.

        Another important reason is there was a rather large jump in the quality of the software running on the bots, and a moderate jump in the quality of the hardware. The integration was much more refined.

        Finally, the course was easier overall this year and the difficult part was put near the end. There was nothing in the course really comparable to Daggett ridge from the first race. Also, pretty much the entire course was graded along with the edges of the road often had banks. We had cliff detection that pretty much went unused this year due to this.

        Overall, it was a pretty good race this year. Stanford did an awesome job and really deserved the win. Not that you guys have that much interest, but we (Axion) ended up in 7th place (right after Ensco) with about 66 miles. We ended up getting stuck in some sand. The current candidate for the cause is a broken sway arm bracket that caused us to pull to the right a bit. Further analysis will be required to determine if that's actually the case.

  • I think having the robots drive would be much safer than having to deal with drunks, rageaholics, and senile citizens who can't tell the difference between the gas and brake.
  • Gray Team? (Score:4, Interesting)

    Anybody know anything about the Gray Team and their bot? Their 4th-place finish seems to be far the best of any of the 'low budget' teams; about all I can find is that it was sponsored by The Gray Insurance Co., that their IT department (and founders who were bored of spending money on yachts?) worked on it, as well as some Tulane students, and that it was a Ford Escape (small SUV) hybrid.

    They don't seem to have a webpage for the team...

      I go to Tulane and I can think of about 5 Tulane students I know who helped with the bot at one point or another including one of my good friends. Tulane was mostly helping out with programming and I know they were using Java. The story I heard is the sailboat Gray Insurance had been spending money on sunk, so they decided to enter the grand challenge for fun. Luckily the car wasn't destroyed by Hurricane Katrina (they were keeping it about an hour outside of New Orleans). Some of the Tulane students stopped working with the project after the hurricane because they are attending school this semester in other states (since Tulane is closed right now), but a few of the guys took the semester off to work on it full time. As a side note, I am impressed that anything my friend touched actually worked and did what it was supposed to since I personally know his track record of breaking things over the past three years (including MY CAR).
  • Stanley would be the perfect vehicle for agressive driver rehabilitation. Replace the agressive driver's vehicle with Stanley and they can do nothing but scream obscenities as it plots its course to their workplace at a blazing 19.1 miles per hour. Three weeks of this and the agressor becomes as docile as a lamb.

    Why is the fact that 5 autonomous vehicles where able to traverse 132 miles not a bigger deal? I hardly saw any media coverage on this (not even mentioned in those closing "isn't this interesting" segments on local news). IMHO, this is another great "first" for mankind on par with Lindberg crossing the Atlantic or Rutan winning the X Prize. In the future, when automnomous vehicles are more ubiquitous, we will see that the pioneers were vehicles like Stanley. These engineers solved (or at least furthered our understanding) some very difficult problems of computer vision and perception. However, whenever I mention the Grand Challenge to people, they just give me a blank look. One person asked me if the Grand Challenge was some sort of football event.

    Oh well, from what I heard no one was too excited about the Wright brothers' achievement at the very beginning either.

    • The last DARPA challenge had some coverage, most of it along the lines of "Gee look at those stupid retarded robots" with shots of them stuck a few yards from the start line.

      This one had almost none. I would like to think that it is because of Earthquake coverage, but there wasn't that much on US TV. This is very sad given the scope of the achievement.


    • I hardly saw any media coverage on this (not even mentioned in those closing "isn't this interesting" segments on local news).

      There was some coverage in Germany: Main news show in at least some channels. Probably due to Volkswagen, then wanted some advertising for their car.
  • Does anyone know how exactly they scored the Grand Challenge? I was watching the leaderboard the whole day as I was coding, and one of the CMU vehicles was the first to finish as far as I can recall...furthermore, the spread BETWEEN the top three vehicles (CMU, Stanford, CMU) seemed to vary from time to time.

    I have my doubts as to the validity of the data since there were also a couple glitches during the race where all of a sudden a bunch of vehicles' mileage and stuff were kicked back by a good amount.

    When you look at the results, and you see two colleges with virtually unlimited resources and millions of dollars spent on their vehicles, huge corporate sponsors and engineers at their beck and call from Boeing to Catepillar, who finished, and then this dinky little Team Grey from a suburb of New Orleans, with a splintered development team as a result of the Hurricane Katrina disaster, and they FINISHED just behind the big guys, leaving other heavily-funded vehicles in the dust.

    Relatively speaking, a small indy group, even if their time was a tad slower than CMU or Stanford, essentially put those three teams to shame when you compare the resources they had available to them.

    The real story here is who is behind the Grey team's car. It must be a far superior design than either CMU or Stanford's considering the limited resources and experience they had in addressing the challenge.
  • "Mohave"? It's spelled "Mojave"?

    See "Mojave Desert", "Mojave River", "Mojave, CA", etc.
  • So much for Volkswagen's 'Drivers wanted' slogan.
  • Has anyone been able to find out the official time (i.e. time with stops/pauses substracted) that TerraMax took to complete the course? I get the impression that TerraMax was really unlucky, getting paused by other competitors many times and then being forced to shutdown for the night.

    Also, does anyone know the top speed that was reached by any vehicle on the course?
