Try shifting the center of gravity forward. Put guitar string wire legs on
the bot so you can control the pitch and yaw of the body weight. If you shift
the center of gravity forward and spin the motor to give a backward kick of
inertia, it may lurch forward. Another idea would be to use suspension
springs to absorb the backward inertia and then recoil, propelling the bot
forward. Sensitive springs with a good easy bounce. The guitar string may be
configured to get a similar effect. But, then you will completely loose the
completely contained, crush proof qualities. Just some thoughts.
See ya,
