Abstract
Recently, many biomimetic quadruped robots have been developed. Most of them use many actuators for running, which causes them to become big in size. We have developed a middle size of quadruped robot by using only one electric motor as an actuator for running. We also adopt to the robot the mechanism which is similar to Theo Jansen mechanism to make its gait biomimetic. In order to put our mechanism into practice, we propose "Modified Gallop Gait" that is derived from bounce gait and gallop gait. The results of the experiment show that the robot runs as the modified gallop gait while its pitch angle oscillates periodically to realize its stable running.
