In the Fall of 2006, the Robotics Club held a sumo bot
competition. The robots were to push the other robot out of the ring. I built
two robots for this competition. Hammer-Bot on the left used a Basic Stamp1
with whiskers to find its opponent, it would then come swinging. The
Spinner-Bot on the right used a range finder to locate its opponents, while
spinning its upside-down stew pot full of sheet metal screws.
