Abstract
A biped robot needs navigation to the destination in achieving its task. This paper presents a method by which a biped robot recognizes its surrounding environment, plans the path to the destination, and moves there. The position and the posture of the biped robot are calculated by landmark observation with a stereo camera system installed on the robot. In order to make it possible for the robot to execute path planning, a grid map is generated by using the surrounding environment information obtained from the stereo camera images.
