In it's day, robots like this one
were common. This robot was made with arms that were longer than
it's body so when the arms rotated, it moved forward. The arms would
roll the whole body of the robot into a summersault. It would then
land back on it's wheel to roll around and repeat the cycle all over again.
Simple, yet fun considering I don't see these anymore.
