This is an assembly kit of a robot that generates electricity by winding up the hand unit (generator) to create electricity to the motor. The motor is run by electricity, but without the need for batteries since all power is created by the supplied hand crank. Crank walking mechanism transmits movement of crank to arms and making the robot walk, with arms pushing like a Sumo Wrestler. Connection between the generator unit and walking mechanism is ensured by a wire harness and connector. Assembly is easy with snap-on and screw in.
