      I've read a few articles about the Grand Challenge and they all seem to focus on CMU, the favorite. From what I understood, pretty much all of that $2M-$3.5M cost figure came in the form of free stuff from Intel, Boeing, and many others. It's not like the grad students are writing $150,000 personal checks to buy parts.

      The students probably can't pocket any prize cash anyway because of ethics rules. If they win, the students will get a rocking party and even more top notch equipment in their labs.

      It's not a race to prove you're better than the other teams and get prize money. It's a race to advance the state of a specific technology. Do you think people are going to get rich winning the X-prize?

    • From articles I've read (unfortunately I can't recall where) the whole DARPA event was used to "scare" one of their existing research partnerships (CMU) into getting their @$$ in gear and producing an automated vehicle - which apparently CMU was lagging on. The event was to show that DARPA could get great research from other sources if CMU didn't shape up.

      The result is that CMU stopped dragging their feet, which accomplishes the main goal of DARPA $1 million challenge.

      Sure it is. Logistics are a *huge* problem for the military, especially one that moves as fast as America's. Remember in Gulf War II that some of the most public incidents of American losses involved supply convoys, not front-line forces.

      With this sort of technology, supply-lines become more like conveyor belts than masses of convoys. They elminate the need to teams of humans to transport fuel, water, ammunition, etc. to the front lines. This increases the pool of human resources available to the military for other jobs, while eliminating the worry of casualities inflicted by enemy interdiction missions.

      Sure, automatic tanks will logically be a followup, but I think the military's mid-term goal is automating the logistics.

      Based on recent experience I would take the military's word for once, though only once. If you look at Iraq most of the casualties weren't in combat. Soldiers in fast moving, heavily armored, M1 tanks really weren't that vulnerable.

      Its probably going to be a real long time before you trust a robotic tank to discriminate friend or foe and to decide when and when not to start lobbing shells. Combat really should have a person in the loop who can react quickly to a complex and changing situation, one that often requires nuance. I wager an RPV tank is the only thing you may see anytime soon.

      But if you look at Iraq the place where the Army is VERY vulnerable is convoying supplies from one place to another since they are sitting ducks for improvised explosive devices and ambushes. I could see robotic transports as priceless for this if they can cope with a predefined route, not run anything over and deal with obstructions.

      Supply lines have always been the achilles heel of occupying armies. Indications are the U.S. military doesn't really need much help in the conflict phase, but it does need a lot of help to minimize the casualties and manpower needed to occupy its colonial empire.
      • I should add robotic vehicles would also be very useful for scout vehicles that are designed to make first contact with a concealed army, find mine fields and generally do a lot of dangerous scouting work which doesn't require discharging weapons. Scout vehicles would just beam back intelligence, draw fire, and be cheap enough to be expendible.

    I know it's much more complicated than this, but they're giving it the knowledge to navigate a route, not the intelligence to come up with its own route. Surely that's missing the whole point of this competition? I read in the last /. article that they're using a loophole in the rules to get so far.

    Seeing as DARPA wants to turn this technology into a military robotic transport, I don't know how valuable it's going to be if it has to be pre-programmed with terabytes of data just to move. What about if they invade somewhere they don't have good maps of? Somewhere with a dynamic landscape (desert, rocks etc)?

    I'm all for innovation, but exploiting poorly-worded rules just to win for winning's sake is an empty victory at best.

    • They are going to be traveling through a dynamic landscape, they aren't just driving over sand dunes or across open desert. They are given waypoints, but the waypoints are each a mile or two apart which leaves plenty of room for pathfinding in the middle.

      If the military invades with these, they aren't just going to tell it to go somewhere and kill someone, they are going to give the machines very specific directions. If they dont have a map...they could probably get one in a few hours anyway, so I don't

      • DARPA are looking to create vehicles that drive themselves. Vehicles that drive next to manned vehicles, and act the same. These vehicles have to react like people - if a bomb drops in the road ahead, it has to know to stop and drive round. It has to figure out the best route available. If it's dumbly programmed with waypoints, one crater and it's toast.

        This robot sounds like it fulfils the rules, not the competition. There's a huge difference.

      From what I understand, the "loophole" allows them to use 1m satellite imagery of the route and, in two hours, plan something for the robot to follow. The robot still has to see its way when it's going, to avoid ditches and rocks and other things--it needs to do "local" route planning at 35mph. Even if the route were totally pre-programmed, the problem of following that route would still be pretty hard over hundreds of miles. You can't just do "dead reckoning."

      What about if they invade somewhere they don't have good maps of? Somewhere with a dynamic landscape (desert, rocks etc)?

      This is in the desert, and they're doing it with only satellite imagery.

      There's a huge amount of mechanical and software engineering in this thing. I think that someone must have exaggerated this "loophole" to you, because it is far from making the project easy (as far as I know, it doesn't help them in the quals at all). The robot is impressive!

      • So they have hundreds of terabytes of information in the back just for shits and giggles? Why isn't anyone else taking that path?

        It doesn't have to think about navigating - they're telling it how to do that. It has to only deal with getting round obstacles in its path. They're removing 1/2 of the problem so they can put their effort behind the other half, which the other teams aren't doing. It just smacks of unfairness, that's all.

    • Red Team is using "the best map in the world" to guide it. They have used topo maps, aerial photography, and a bunch of undergrads to painstakingly map out the terrain of the possible courses.

      All competitors are given the actual route as a series of GPS waypoints a few hours prior to the race. Red Team is going to send those waypoints back to CMU, have the big iron there figure out the best course based on all the map data, and then download that course to the robot prior to the start. In a way this is cool, but it seems like they are using a loophole. A much more interesting problem would be to navigate a course that you know nothing about other than the waypoints.

      The other teams are using techniques that require more onboard intelligence and route finding. The most interesting vehicle is from Cal. They have a motorcycle. Even though I went to Stanford I am rooting for the Cal motorcycle to do well since they have the most unique vehicle. Hopefully the team of Stanford alums (already dropped out) can come back next year and beat them.

      • You are right that it would be much cooler if the robot could find its way without the map, but for the purposes of the military it is plenty good that it reads a map and only does obstacle avoidance in real time. This is the way that a tomahawk cruse missile works and it works pretty well. One of the first things that the military does in a conflict is update the maps and reconnaissance for the area.

        This also would great as a civilian technology. If I could drive my car to the interstate and hit an autopi
      • The point of the Darpa project is to advance technology for driverless military vehicles, primarily for convoy work. To my mind, creating a computer system to quickly plan out routes based on intelligence is an important part of a practical solution.

        Not only does it more accurately reflect the technology's intended use-case in the military field (convoy operators would lilely be given a general route a couple hours before a mission, instead of simply told, 'get it to this point and leave right now') but it
        • Maybe I should clarify. From what I have read I think that the Red Team will do better than any other group. They have probably put more money and time into their effort than any other team (even though they started later than some) and they deserve to do well.

          That said, in a dynamic enviroment you won't always have the luxury of "the best map in the world". While this works well for convoys there are other situations where the ability to deal with a changed landscape (due to war or natural disaster) o

    • I'm not sure that it is a loophole. It's not as challenging as doing it the other way, but let's face it, this is being done for the military, and you're extremely naive to think that the military doesn't have precise topography maps of the entire world, or that they can't obtain such maps in short order. Remember, a key component to cruise missile technology is topography. Remember in GWI, the cruise missiles took hours and hours to program before launch. Now, they can be reprogrammed in minutes.

But the map doesn't show every little bend in the road, every little obstacle, elevation changes, etc. You have to do all that while you're driving the roads. The autonomous vehicle has to do the same things. You don't think that's impressive?

      So you'd rather have them spend a few billion on a single supplier, who may not be able to deliver anything, and then keep all the technology as classified for an unknown period of time? Yeah, that's a great use of taxpayer money.

      Instead, they put out a challenge that allows both public and private industry to participate.

    Here's the second day field report sent to me by a friend who is out attending the DARPA Grand Challenge. Posted with his permission:

    Attendance was about the same today except it didn't appear that there was as many media representatives present. Again temperatures were in the 90's. I acquired a media pass today and was allowed access to almost every area of the speedway including the pits and the start line. This will allow me to film each entry up close and interview members of the teams. DARPA is

  • Hopefully, this is just the first step towards that goal.

    Given the 40 or so years between the DoD's ARPA net experiments and what we have now, it isn't that far fetched.

    I could have saved them $250,000 in sensors by installing a $100 roll bar!

    I went by the event yesterday as a spectator and got to see Red Team do their run. Of the 23 teams who made it this far, they're the only one that has completed the qualification course so far. People complain that they have a more accurate map and that they're not doing real AI, but based on their performance on this surprise course, they have a real obstacle avoidance system.

    In one section there was a minivan parked in the center of the GPS path. Of the eight vehicles I saw run, only three made it past the car. Three hit it, and the rest failed before making it that far.

    It seemed that the biggest problems teams had were getting GPS right. Several drifted off course or turned the wrong way, going off course. One got the next GPS coord inside of its turning radius so it kept circling a spot until they turned it off.

    Lots of great designs though, and some really impressive engineering.

    You can look at the latest pictures, the teams' relative positions, and status charts.
  • The New Scientist has a nice writeup of the qualifying round as it now stands. The last paragraph is particularly interesting.
    DARPA says it will do everything it can to make sure all vehicles capable of stopping safely qualify, which includes allowing them multiple chances to qualify and perhaps ignoring rare crashes. The finalists will be announced on Friday morning. 94757

    I withheld midterm grades of our course, pending the outcome of QID, since this is a third of the grade. Since QID went well, grades will be good, and it will be a pleasure to assign these.

    Withold the grades, and students will do anything. (Note to Theory profs out there: withhold grades until someone proves P != NP )

    Towards the end of this year, PCI-Express and next generation graphics cards using them will come to market.

    How is this significant for the DARPA race?

    Well, newer generation graphics cards with highly programmable graphics pipelines can act as very powerful SIMD processors. Up until now, their capability has not seen much use outside of graphics because the AGP bus allows data to travel at full bandwidth in only one direction at a time. This meant that every time you need to download data from the video card, you had to flush the AGP bus, loosing or delaying the uploaded data.

    With PCI-Express, data could travel both ways concurrently at full bandwidth, so there's the potential for using the graphics card as a specialized SIMD processor.

    I bet much of the processing for the vision and obstacle avoidance could be done on a GPU. If that's the case, instead of having a 1.5 gigaflops CPU per pc, you could have 10 or 20 gigaflops (IIRC) of processing power at your disposal for little over $1000, thus making the necessary computing hardware much cheaper.

    Currently, the CMU team, for example, has multi-itanium servers aboard their Hummer, which is NOT something doable on a shoe string budget.

    Man, these teams are using the wrong military vehicles. Humvees? Supply trucks? What the hell is that? Seriously man, strap a GPS system onto an M1 Abrams and open that baby up.

    I say screw collision avoidance. Go for collision dominance. Any obstacle capable of stopping a 65 ton tank travelling at 45mph is gonna show up on the mother f**king map.
