class=015402220-09012008>My childhood electric football players used two bits of
clear plastic sheet strips. Forward, it had one strip, running from side to
side (e.g. left to right of the player) set at an angle so the top of the
strip was forward placed and the bottom of the strip was aft relative
to it. The other strip in the back, also ran horizontally across the players
bottom pad, but it was set in vertically, without a cant or direction to it. I
was pretty sure this arrangement was what made the players always go (roughly)
forward when the floor vibrated. (Man that thing was loud! Like a 60-Hz
transformer hum feed into a megaphone.)</SPAN></FONT></DIV>

class=015402220-09012008>Anybody got ideas how we're going to put directional
controls on these bristle bots yet? So far, there are varied reports on making
catamarans turn by using only one motor, mostly not successful. To throw a
mechanical weight, or bristle direction control seems problematic. Even micro
servos seem too large, as big as the rest of the robot. We need smaller
actuators than even that.</SPAN></FONT></DIV>
