Gait Analysis and Realization of Quadruped Bionic Robot with 8 Degrees of Freedom

Since the quadruped bionic robot can be widely applied to different terrains, the research on it has always been the focus of robotics-related field. This paper designs a quadruped bionic robot with 8 degrees of freedom. We analyze stability and movement speed of the robot in different gaits. The gait focuses on crawl in triangular gait and trot in diagonal gait. In the case of using 8 degrees of freedom (two per leg), through gait analysis, 3D modeling, physical testing and using larger sole to improve stability, the designed quadruped robot can achieve stable and fast movement.
