The Realization of the Super Multilegged Passive Dynamic Walking

摘要

A passive dynamic walking robot can walk down a gentle slope naturally without any actuator or controller, only by potential energy. Therefore, it is thought that the principle of walking exists in this phenomenon. By current researches, the passive dynamic walking has been confirmed for two and four. However, it seems that it is also important to study passive dynamic walking for more than 6 legs because there are many creatures that have more than 6 legs. In this research, a passive dynamic walking robot with more than six legs was analyzed by a simulator. As a result, it was confirmed that passive dynamic walking even for 20 legs could be achieved. Furthermore, its gait could be changed by changing the body structure. In addition, the differences of stability depend on the number of legs resulted, and this differences disappeared by changing the position of the pitch spin parts. Moreover, its stability was very high, so it could walk on the contoured ground.
