Fluffy is a quadraped robot that requires one RCX brick, three motors and two touch sensors. Each side has a motor that drives a shaft connected to two worm gears. Each worm gear powers one of Fluffy's legs.
Fluffy's direction of movement is controlled by reversing the opposite pair of legs. This enables Fluffy to turn and pviot in a small area. The third motor drives Fluffy's mouth. When Fluffy's whiskers contact an object, Fluffy will pivot towards the object and attempt to bite it.
