    Ben Franklin Racing [benfrankli...ngteam.org] (a collaboration between UPenn, Lehigh and Lockheed Martin) also finished within the 6 hour time limit.

    The judging will certainly be interesting.

      Yeah, but I think Ben was penalized for its initial delay at an intersection for too long at the first mission. After they rebooted it seemed to be ok and actually did pretty good getting around the intersections it had problems with. When Honeywell was taken out of the race, Ben was waiting behind it at the stop sign until they pulled Honeywell out but I don't think they penalize for that.

      It is something to note that the two teams that finished but finished last were MIT and Cornell which had a collision with each other somewhere around Mission 2. But they both finished which is pretty awesome considering what it takes to run this corse.

    I will admit that I haven't read up on the exact rules , but I find the name Urban Challenge to be a bit misleading. From what I have seen the environments are very sterile compared to real life urban environments , yes the name gives the impression that robots can now drive in a ciry like New York. This reminds of the 60s I think it was when computer scientist claimed that because a robot could restaple boxes , we will have androids in 20 years. Then it became clear that the algorithms didn't scale well with the complexity of the environment ( to put it nicely) and Artificial Intelligence became a somewhat disappointing field for the general public atleast.
        All I am saying is that we and the tech journals should be carefull with exciting names like "Urban Challenge" or "60miles through urban landscape".
        Other then that , congratulations to the teams , I didn't expect such good results.

      That's the problem with hype. They have cried "wolf" too many times. It was the same thing at the end of the 19th century, when people were researching flight. Steam engines were too heavy for their power, airplanes had to wait until engines became powerful enough. There were many people, among them some respectable scientists, that wrote articles "proving" that heavier than air flight was impossible.


      At this point, computers are too expensive and consume too much power to be practical for anything that involves "human-like" intelligence. But we are making progress, at least we do have unbeatable chess-playing computers, a feat that not so long ago many people considered impossible. Of course, computers do not follow the exact path of reasoning that humans do when playing chess, but they are unbeatable anyhow. Airplanes do not flap wings either, but they fly faster and higher than any bird.


      Unless Moore's law ceases to function, we can expect desktop computers with a complexity comparable to that of a human brain in twenty years or so. Given the hardware, it's only reasonable that someone will invent a way to make a computer emulate a human brain in its full power, just like people invented machines capable of flying when they got engines with enough power.

          Actually, I don't think its not the fault of emerging technologies but rather emerging technologies must scale to the following questions:

          1. Is it profitable?
          2. Is is mass producible?
          3. Does it follow a decentralized free market model rather than a centralized regulated model?

          The reason we don't have AI, Civilian Space Travel, and Flying Cars is because they meet none of the 3 criteria I mentioned. AI today would require a computer that costs billions of dollars to build, a civilian space program would cost billions to build, and the flying car industry would be too regulated and dangerous to even consider marketing to people.

          Which is why cell phones and internet caught on because those things are quite decentralized in how they work (Yeah I know the cell phone companies are monopolies but you can sell someone a cell phone and it doesn't cause any problem with the rest of the system etc etc)

        I hear what you are saying - I also believe that anything is possible given enough time and hard work. Yet I think you are VASTLY underestimating the task of creating a human-like intelligence. Faster and more powerful != More Intelligent. Flight and chess are child's play compared to the human mind. It's also a false assumption to believe that a Turing architecture machine will be able to simulate the human brain with whatever specious equivalence used to compare human and computer processing power. The brain is NOT a computer. Computers themselves are simple expressions of a mere slice of how we understand our own mental processes to work. Do you know anyone who understands how any mind works, let alone their own, whether they be computer scientists, psychologists, cognitive scientists, or neuro-biologists? To put it simply, in order to expect a human-like intelligence in 20 years requires two things we do not yet have: An understanding of human intelligence, and a hardware architecture that is able to implement it.

          Sorry to nitpick, but yes, it does. Intelligence as a function of speed, power, and strategies remains monotonically increasing with speed and monotonically increasing with power, up to the bounds of the complexity of the problem domain (cf Go and Tic-Tac-Toe). It just so happens that there will be diminishing returns on existing strategies, and finding new strategies will at some point be more cost-effective than making things faster or more powerful.

        You link computing power with intelligence, clearly this means you now NOTHING about programming. Doom does NOT become F.E.A.R. by simply running it on a faster CPU.

        SOMEBODY has to write the program that becomes the AI. It REALLY does not matter that much how fast the underlying hardware is that executes that program, the simple fact is that AI code right now just ain't that smart. Not even if an AI can take weeks to calculate can it come anywhere close to what a human can do in terms of reasoning with the input available.

        A smart program that is just very slow would be an amazing breakthrough and if that happened then all we need to do is wait for computers to get faster, but right now the AI code just ain't there. If it was, it would long since have been given a supercomputer to run on.

        These robots in the challenge have a simple task that any human can do, "see" the enviroment, and act upon that information. For years this has been attempted and the systems just ain't getting any better despite the fact that computing power has skyrocketed. Simply put, no code exists that can take a video image and turn that reliably, consistently in information that tells the decision making software what the enviroment is like.

        For instance, the detection systems have problems with blue colored cars against asfalt. Consider a human being, put a car painted blue against a background painted the exact same color in blue lighting so it totally blends in. WOuldn't fool a human for a second since we would still see the windshields and through it the interior of the car and reason out that there must be car there even if we cannot see the bodywork.

        Same with an other obstacle, a barrier hanging in the air, the teams actually complained about this because they thought all the barriers would be on the ground. This shows you why AI programming is so bad, the programmers are morons, the barrier involved is very common at road blocks. The car, designed and programmed to only scan the ground is unable to determine that a barrier might higher up.

        Worse, when it hits it, it can't react to it. The cars have to be stopped, not one of the cars, not even that best was able to simply stop, backup and try a different course.

        You can throw more GHZ at it, but all that will give you is faster dumbness.

        What happens when a computer has the same complexity as the brain? You will have a very fast, braindead piece of machinery. It is the programming that matters.

        Your anology to flying is flawed, we knew that things could fly, gliders had been around for ages, all that was needed for a power source that had good enough power to weight ratio. We do NOT have the AI code or any idea how to make it. Compare it to say faster then light travel. We don't know how, so claiming that if only we develop an infinite source of energy we can do it, is flawed.

          I fully agree that most don't understand the magnitude of the problem and we have a very long way to go, but we know for a fact that it's 100% solvable. Nature already did it.

            I'm afraid I have to disagree with your logic. Yes, physics as we know it would be violated by faster than light travel, so we certainly don't know if it can be done at all. Your argument for AI is flawed, though: simply because we know sentience is possible, it does not follow that we know sentience can be created artificially. We know sentience is possible in biological organism, but we do not know if it can be recreated in a machine. Even if your definition of AI includes creating an organism that has sentience, as opposed to the current understanding of AI (machine/software-based), your statement that "it's 100% solvable" does not necessarily follow.

            I think it's somewhat more likely than not that we will eventually develop true AI, but I don't think you can jump from the mere fact that sentience exists to saying that artificially duplicating it is a given.

It however showed very clearly that Deep Blue had been setup by HUMANS to beat Kasparov, when he became another player by changing style, the computer could not cope, it had no AI to deal with this.

        This has little to do with Moore's and a lot to do with the fact that sensors do not follow Moore's law. We were using the same sensor technology as was available 15 years ago with marginal to no improvement on quality or capability.

        The software side of this DARPA Urban Challenge should consist of no more than an enormous, but straightforward, state machine that contains all the logic for traffic decisions. Plug that into a simulator and you've got the main software part done.

        The problem everyone had out in the field for the qualifiers (I was on one of the teams) was perception. How do you know what you see is an obstacle? And how do you deal with false positives, and more importantly, false negatives? Some people believe in cross referencing sensor data, which is called sensor fusion. It is difficult, to say the least, to characterize every possible obstacle that ought to be considered a true obstacle if it lies on your vehicles path, let alone have a 10^-6 failure rate for improper detection.

        The highway lane following has been solved since the 70s, check out R.E. Fentons work on Automated Highways in Transportation Science (1970). We had some "recent" developments in the early 1990s where we got some autonomous vehicles to do the autobahn at 100mph with more modern sensors and vehicles, but really didn't improve that much because the sensors aren't there yet.

        Your sensor choice goes something like this:
        $75k for a Velodyne 3D laser system
        $5k for the SICK 2D (planar) lasers
        ~$25k for stereo vision cameras (per set)
        ~$1k for radar
        $75K for the Applanix integrated GPS and IMU

        The Velodyne is a spinning set of 64 lasers, with 64 photodiodes. Each manually placed so that the photodiodes are aimed precisely where the lasers are pointed. The entire head of the unit spins at ~2Hz and generates 1 million points per second. Most of the teams that bought one mounted it on top of their vehicle. This sensor is great if you have infinite processing power available to crunch the data and turn it into cost maps. It however has some serious problems: it's very expensive, it's not mass manufacturable, the point data for a rock and a shrub are indistinguishable (a weakness of all lasers), some obstacles we're interested in absorb laser or reflect it away from the photodiodes, it has too much information, and it has moving parts.

        The SICK 2D planar lasers have more or less the same problems, except there's less data to crunch of course. These lasers also have moving parts internally, which spin a mirror at maybe ~20Hz to get distance data over a 2D plane. Same issues as the Velodyne, except it's manufacturable (has been for 15 years now).

        Stereo vision is really hard to do right. When you have roughly a year to develop the platform and the algorithms, I don't expect much, and I didn't see much. This may be the answer in the future for passive detection, but I don't see it working at the moment.

        RADAR is the right sensor for this type of work. It gives you distance and speed. If you're clever it also gives you the "cost" of a particular object. Radar is how you can tell the difference between a shrub and rock, or a car and a plastic fence. The real cost in the RADAR is not the sensor, but the $100k guy who knows RADAR well enough to set it up right and get good data out of it.

        The Applanix GPS and IMU with 200k RPM laser gyros are not manufacturable and not practical for autonomous vehicles because of the cost. Perhaps the MEMs solutions will catch up and make IMUs cheaper, but in the mean time we're stuck with these systems if you care about your position.

        That's my take on it. Improve the sensors and we'll get autonomous vehicles. Buy another Cray, strap on a generator and a multi-ton air conditioner is not the solution. We need to reliably and cheaply generate cost maps that are relevant to the vehicle that's being automated. Once that's been done reliably, we will have autonomous vehicles. Cheers.

          The sensors are coming. One promising sensor is "flash LIDAR" (or LADAR, "light" vs "laser"). Here's a mention from Google's first result (for a Grand Challenge thing in 2005):

          True 3D solid-state flash LIDAR devices exist. We've visited Advanced Scientific
          Concepts in Santa Barbara, CA, and have seen an eye-safe 128 x 128 pixel solid state
          flash 3D LIDAR suitable for outdoor work in operation on an optical bench. The device
          consists of two custom chips bonded back to back using ball grid array techniques. Th

          Stereo cameras are a kind of sensor that improved a lot on the last 15 years. Today we get better prices, better focus, the entire set is smaller and lighter, uses less energy...

          Yet, we can't make a good use of them. That is because there is no computer we can put on a mobile robot able to get all the data a stereo head gives us on real time. We fall back to getting partial data, and optimizing for what we think the robot will face. We lose lots of flexibility

            I agree that the algorithms are by no means a perfected art, yet. However, once they are chosen and run through the appropriate testing gauntlet for acceptance with respect to the requirements of the project, the software becomes firmware and semi-custom hardware. The embedded solutions are way more viable than running the dual quad core intel Xeon boxes with external generators, air conditioning units, Windows XP, etc. It's just a matter of getting the appropriate development time for getting the false pos
            • "...the software becomes firmware and semi-custom hardware."

              We are still not capable of gethering all possible info from a stereo head (at several fps), even with totaly custom hardware and the fanciest algorithms available. Well, theoreticaly, we can, but it would suck so much power (besides being expensive) that a mobile robot wouldn't go anywhere.

              I disagree that stereo vision isn't the way to go. Jamming is too common on medium-to-small sensors, even from natural sources. Also, a passive sensor could

      It's all PR.
      But, PR is vital to getting $$ from a basically anti-scientific federal government.

    Some of the robots were paused for a long time, and each was clocked individually. There is really no point in speculating as to who the winners are, because in addition to the time, how well the bots obeyed traffic laws as well as just how safe they drove in general are all taken into account. We should find out the scoring soon enough (sometime this morning.)

      10 years. Tops. In 20 I expect it to be illegal for a human to operate a vehicle on a major roadway. 50% of all accidents are caused by drunk drivers, but 99% of all accidents are caused by human drivers.

And if all those vehicles operated on a mesh network, communicating with themselves and with remote data sources (weather services, etc.) traffic jams could be a thing of the past, and we'd all get where we're going more safely, a lot faster, and on less fuel. If some blockage occurred that would otherwise cause traffic to pile up, cars could automagically route themselves around the problem. "Sir, we are talking an alternate route to the airport because

    Why is NOW the first time I've heard where it was being held? I looked through the past /. articles, and NONE of the pages linked bothered to put in the two magic words to tell readers where it was being held. You had to navigate DARPA's site to find that info, so basically, only those people already determined to go would find out where it was happening.
