"The robot is based on an RC car chassis from Radio Shack. It uses the existing H-bridge and motors and adds circuitry to sense the robots speed from the back EMF of the motor and PID style equations to control speed. Using this speed signal, it could calculate distance traveled within 5 or 10 percent."
