2A1-F30 Analysis on Jumping Patterns of 1-DOF Legged Robot

In this paper we report on experiments on jumping motion using a 1-DOF legged robot. First the dynamics and basic characteristics of the 1-DOF legged robot are derived. Three jumping patterns based on the sliding contact between the leg and the ground are represented. In particular two-step jumping method is newly proposed, which is effective for high-speed and powerful actuator. Next the influence of structural parameters of the legged robot on jumping motion is analyzed. It has proven that the optimal parameters for high jump exist.
