Abstract
Various crawler type rescue robots have been developed. These robots are used for exploration activity in the environment where a person cannot enter and must move around the rough terrain such as debris zone or mud. In addition, the robot must perform exploration activity quickly. Therefore, coexistence of the machine performance on rough terrain and the running speed performance is required. This study propose a small size mobile robot which have two connected crawlers and flexion jump mechanism. It is confirmed that degradation of the machine performance on rough terrain by the downsizing can be improved by the deployment of the flexion jump mechanism.
