Small robot made from hacked toys

This video demonstrates my first successful robot. It consists of a Basic Stamp microcontroller, a snap circuits car, and the head of a toy robot. A servo motor rotates the head, which contains infrared sensors to detect obstacles. The motors are controlled by relays, and their power supply is completely separate from the rest of the system. The robot is surprisingly good at detecting obstacles, but as you can see in the video, it tends to get stuck in corners.
