In this paper, we discuss about locomotion of snake-like robots on uneven terrain. In recent research some snake-like robots have been developed which have ability to advance on uneven terrain, but the control has not been established. In this paper we propose a control method using a touch sensor located on the head of robots, and verify the effectiveness of propose method by experiments. We think the result of this paper will contribute to the study to put snake-like robots to practical use.
