Application of Electronic Compass and Vision-Based Camera in Robot Navigation and Map Building

This paper studies the problem about robot path planning, and puts forward an application of electronic compass and vision-based camera which used for robot navigation and map building. We can make sure the azimuth angle of robot by installing electronic compass on robot´s control panel, and then locate the robot through the image information from the camera which is installed on the robot´s head. Suppose the mobile environment of robot is indoor, and we can determine the original location, current location of robot and the object´s location through combining the data which from electronic compass with the data from camera. We also can build the map information by a comprehensive analysis of these data and build a new data structure which is special constructed for electric compass. The result shows that the micro system provides a good solution of map building, navigation and location in the laboratory environment.
