<p>Several animals such as snails and earthworms exhibit crawling locomotion by propagating the bodily wave of expansion and contraction to adapt to various environments. In this locomotion, not only expansion and contraction of the body but also friction with the environment is considered to be an important factor. However, existing studies has not sufficiently integrate peristaltic movement with friction control. Therefore, in this research, we propose a decentralized control of crawling locomotion that well-integrates peristaltic movement with adaptive friction control, and simulation results represent that a crawling locomotion with high environmental adaptability was realized.</p>
