  1. I've got an idea for a simple robot-toy. RF controlled with two wheels,
    independently driven on either end of a cylindrical body. The body
    should be counter weighted, so that driving the motors will propel the
    robot forward, driving them at a differential speed will cause it to
    turn (steer).

    I want to build this in a section of 2" diameter iron pipe. Each 'wheel'
    will be a pipe end cap with the threads milled out and suitable bearings
    so they can rotate with respect to the body.

    The idea is to leave it someplace in the open and wait for the bomb
    squad to sent its robot out to take a look at it. At the last moment,
    the pipe just rolls away a few feet. A chase between the two should make
    for some really interesting footage on the 5 o'clock news. ;-)

    I wouldn't advocate doing this, but note that you can roll a pipe or ball by
    moving a weight within it (cf. hamster in ball) -- you do not actually have
    to have wheels on the ends.
     
  3. Might have some trouble steering a pipe this way. I'm anticipating a
    long chase.

    Anyway, I'm going to have my legal department advise me on any problems
    that might arise, no matter how trivial. ;-)

    YOu could use a combination of the two - use the dangling weight, and
    have _one_ wheel able to turn relative to the pipe, which would let you
    steer the thing.
    Can you say, "Homeland Security?" ;-)


    Good Luck!
