| Outline of Final Research Achievements |
In this research, we built a new method to stabilize a walking motion of a quadruped robot to a target limit cycle by combining a walking pattern generation method and a multi-degree-of-freedom vibration control. By applying our method to the quadruped robot with 2-DOF elastic legs, we designed a limit cycle control system that can realize the trot walking and the bound running by using the elastic energy of the legs, and confirmed its effectiveness by experiments. In addition, we verified the gait pattern that maximizes the walking speed and clarified the relationship between the walking speed and the walking pattern parameters.
