Abstract :
A simple and intuitive heading direction sensor for mobile robot guidance is reported. The sensor consists of a needle-type analogue magnetic compass, image camera, and digital processing module. The image of a magnetic compass is captured by camera and is processed to compute the direction of a mobile robot.
