Tamiya 71121 Walking Robot 2-Legged w/Wind-up Generator

Power in Your Hands
This wind-up generator set allows you to create electricity to power your 2-legged walking robot. You create your own hydro-electricity by turning the generator’s handle which puts the electricity producing motor into action. Through this simple action you create ample electricity to power your robot, therefore no batteries are required! You have a choice of using either an ostrich’s or a duck’s head (both included) for your robot. In addition to the easy assembly, the generator unit and the robot can be securely attached with connectors.
