Sumo Wrestler Robot w/Wind-Up Generator

Here's an educational and fun model of a robotic Sumo wrestler that's powered by a hand-cranked power generator! Electricity is generated by cranking the handle, which operates a gear-increasing generator system. Turn the handle clockwise to go forward, and counter-clockwise to move backward. The cranking speed directly affects the speed of the robot's movement! The little legs feature sure-grip rubber to move forward and backward, and the arms are connected to replicate the typical Sumo pushing action! Generates about 2.5V (unloaded). Includes two motors. Assembly is required; a screwdriver is included.
