Abstract
The long and thin snake-like robots have became popular for searching narrow spaces, such as debris of the collapsed buildings under the impact of large-scale disasters. Multi-link serpenoid robot (MLSR) has very high performance on continued irregular terrain. But, the robot stuck on discontinuity terrain easily. This paper describes multi-link serpenoid robot which has torus crawler. We develop prototype MLSR and experiment. As a result, the robot moved in torus crawler.
