4-Legged Walking Robot w/Wind-Up Generator

Here's an educational and fun model of a four-legged robot 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 four legs let the robot move forward and backward with stability, and the eyes are connected to the legs and move left and right as it walks. The tail is mounted on a coil spring to produce hilariously comical action! Generates about 2.5V (unloaded). Includes two motors. Assembly is required; a screwdriver is included.
