    The American teams were fairly disappointing.

    The American teams that brought their stuff were South Dakota School of Mines & Tech (SDSMT), Southern Poly State University(SPSU), Arizona State, and LeTourneau.

    The problem is that SPSU, SDSMT and LeTourneau (who all used helicopters) all spent ~1500 bucks on a navigation system (made by rotomotion), instead of being creative and making their own. To make matters worse, the rotomotion system is horribly designed and their navigation system is still very unstable. SDSMT crashed their heli hard the day before the competition, and still had problems. SPSU had stability problems because of the rotomotion. LeTourneau didn't compete because their basic RC communication wasn't working right.

    Arizona State isn't much better though. Their planes use a CloudCap navigation system. They were able to fly to different waypoints last year, so all they had to do this year is find the iarc symbol on a building. They spent 30-40 minutes on each attempt (which is LONG!), crashed two planes, and had no success. Their method of finding the symbol was to buy an expensive image processing system (read their paper about it) instead of taking the time to study image processing.

    Aside from all this, I was really impressed by the canadian teams, which built their own navigation systems. Simon Fraser had a flight control system for their heli that used neural net controlled PID controller. They did two small demo flights and they were damn smooth. Their only problem was having a stable altitude.

    Waterloo won first qualifier using a plane, and was the first team to do it with their own navigation system. Hats off.

    1. Robotic helicopter with a very hot engine and a straw sticking out the bottom.
    2. 55-Gallon drum of gasoline outgassing from a hole where the straw goes in.
    3. (In the words of that "Dances with Wolves" guy from "The Red Green Show") BOOOOM!

    Gasoline isn't explosive unless vaporized. Catching on fire is a concern, but hell, actively cool the refueling station. But yeh. Even a failure could be quite the fireworks event. ;)

    Gasoline isn't explosive unless vaporized.
    Which is why I wrote "outgassing".
    While I wrote the post as a joke, here is how I envision the explosion could take place:
    1. Outgassing gasoline vapor ignites from coming in contact with the hot model helicopter engine.
    2. The explosion procedes along a gas 'trail" to the drum opening.
    3. The explosion near the opening rips the opening wider, and/or maybe creates new openings nearby.
    4. Turbulence and high pressure from the explosion forces atmospheric oxygen through the opening(s) into the drum.
    5. The explosion continues into the drum.
    6. The gasoline vapor/oxygen mixture inside of the drum ignites, blowing the drum apart and turning much of the remaining gasoline into an aerosol, which quickly vaporizes, mixes with the surrounding atmosphere, and ignites.

    So you're suggesting that not only do I isolate this from my body and important properties, but that I set up a camcorder to prudently record the expensive but satisfying entertainment? Fair enough, but whenwe get this on slashdot, you're going to have to mirror the mpeg too....
