BrickPi is a system that converts Raspberry Pi into a robot. The project is a board and case that connects LEGO® Mindstorms Sensors, motors, and parts to turn your credit card size computer into a robot. The BrickPi allows you to connect up to 4 NXT or EV3 Motors and 5 NXT Sensors. It has a 9V battery power source that powers the motors, sensors, and Raspberry Pi, un-tethering the Pi from the wall. It has a sturdy case with holes that snap with LEGO parts. The brains of a Raspberry Pi joined with the LEGO building system.
