Grand Challenge 1, Competitors 0
Ivan writes "According to the DARPA Grand Challenge Status Board, 2 bots were withdrawn before the race started and the remaining 13 were all disabled. Red Team and SciAutonics II tied at 7 miles, a bit short of the 142 miles required." CNN has coverage and interviews.
Has the "privateer" race been done? It would be nice to see a privateer complete the challenge.
I think that even though they only got 7 miles into the course, thats still damn good engineering. Maybe next year they will have worked out what has gone wrong and figured out a way to flesh out an autonomous robot (Or hide a midget navigator somewhere!).
The whole thing makes you conisder just how much processing power we use to control our speed around curves and avoid potholes when we're driving. We can integrate a hell of a lot of information, process the relavent signals and adjust our behavior in milliseconds. And that's not adding the additional struggle of trying to get your iPod to play through the stereo system....
It means that autonomous fighting machines are still some way off.
I suspect that the first industrialised nation that develops autonomous fighting machines will take over the world (or at least have a damn good go).
In the free world the media isn't government run; the government is media run.
One of the rovers got tangled with barbed wire, another had a malfunctioning satalite navagation system (GPS?), one broke its axle, and one rolled over... So its not as easy as it seems, the terrain must be pretty rough to have a car over turn or break its axle.

Yes, this was a grand challenge. But it would be nice if teams could solve part of the problem at first, get some recognition and minor prize money for that, and then move on.
So perhaps step one should have been just doing a long ordinary road course, minimal obstical avoidance, just handling roads, turns, potholes, ramps and even traffic lights (where you are told they are).
That contest would provide useful civilian tech and also useful military tech in terms of a autonomous vehicles to carry cargo in a controlled area with intact roads.
Or you could also imagine autonomous vehicles which handle roads, but then get to a rough patch they can't handle. At the rough patches you station soldiers who drive/remote control the vehicles over the rough patch, but you need far fewer because they stay in one place and only do the rough patch. Let humans do what they can do and computers do the boring long-haul road drive.
Next, hold a contest for a shorter rough course with obstacles.
Finally, combine the two.
Has it been over a year since you last donated to the Electronic Frontier Foundation
Just like 1000s of geeks worldwide, I watched this with great interest. But the whole organization thing left me with a funny taste in the mouth.
It seemed as if the group that could throw the most money at the "problem" would win. Take the CMU team for example: they paid for a high-res survey of the area; had undergrads map out each and every obstacle in all of the possible paths; etc. Now, if the goal of this "grand challenge" was to unleash the entrepreneurial spirit, then it failed. Money != Entrepreneurial spirit.
Taking lessons from the RoboCup people, I would have preferred that DARPA organize it as follows:
- Create a simulator for the sensors, and design a small (virtual) course for this simulator. Let people develop algorithms using this simulator, and have a competition in this virtual simulator to select a set of (say) 30 teams.
- Provide each of these teams a platform: a humvee equipped with the sensors (actual ones from (1) above). Of course, if a team wants, it can add its own sensors.
- After some time, hold a "grand challenge".
- Analyse the approaches taken by the various teams, and (important) share the code among the teams. If a team designs a new sensor that is useful, get copies made and share with the teams for the next iteration.
- Go back to step (1) above, and repeat.
Preference could be given to schools or efforts involving students, as not only is this a great learning experience, but also it will be a great motivator.Just look at the technology gap between CMU and the rest of the entrants. It is quite an achievement that someone was able to equal CMU in performance.
There are a lot of smart hackers out there who would love to take a crack at this problem, but the lack of hardware is a serious hurdle.
I was thinking about that a few months ago when I was working on a film shoot. I had to run some supplies between a remote location and the base camp. The terrain was really rough-- this was a forest, and it had a lot of trees, roots, rocks, crevices and the like. And I absolutely, positively had to be at the base camp ASAP.
I found myself running as fast as I could, but my mind set up an interesting pipeline. I was always looking five to eight feet in front of me and my brain feverishly tried to parse out what was a rock, what was a branch, what was a big root, what was sloped ground, what was even ground, etc. Then, that information got passed to a route-choosing part of my brain that decided where the best place was to put each foot: left, right, left, right. That information, in turn, went to my brain's motor department, which was actually in charge of balance, weight distribution, and muscle movement to actually put the feet where they were supposed to be and keep my momentum without falling.
I call this a pipeline because my eyes never left that five-to-eight foot range. When I was selecting any bit of route, I was already looking at the next bit of route and stepping on the last bit of route. I never looked at my feet, but somehow always put them where they needed to be.
I wouldn't make such an analogy anywhere other than slashdot, but I could feel that the load average on my brain was as high as it could be. I didn't have any free cycles to think about my day, or have a song in my head, or think of my next joke, as I usually do. Every ounce of my concentration was going to these automatic, practically sub-conscious processes. I know was processing as fast as I could -- any faster, and my brain would tell me, "I can't parse the terrain that fast," or "I can't decide on a route that quick."
Don't give me any credit for it, because it has nothing to do with knowledge or intelligence, but I was solving an extraordinarly tough problem very quickly. In short, if I could bring my brain to the edge, I can see how tough this is for the DARPA contestants!
Both CMU and Caltech seem to have failed on Power Line Road near Camp Rock Road, That's a rather boring piece of terrain, and seemingly easier than the first two miles. Again, what went wrong?
In fact, it is not even clear what we can learn from failure like that, which we could not learn otherwise.
Flashy things like this race do not necessarily tell us anything more about deep problems of AI. One can spend millions and millions and not get any closer to the goal.
In World War II a soldier was sent to drive a truck, and if he fails... then another, and another. Today we can send such a robot. It is safe from snipers, and if it gets hit with a shell it will be simply replaced.
Machines like these can -already- be used to patrol large territories; with improvement, they will be really good at that.
