LEGO MINDSTORMS AlphaRex controlled by a Wii balance board

Fun & Games Robotics Technology

LEGO MINDSTORMS hacker Akihiro Uehara built an interface between an AlphaRex and a Wii Balance Board.

User can control the robot’s leg motors speed and direction by changing the vector connecting user’s center of balance and center of the board.
I have designed this application for elementary school kids in a science museum exhibition.
