| 英文摘要: |
| Spinning gait is valuable for quadruped robot, which can be used to avoid obstacles quickly for robot walking in unstructured environment. A kind of bionic flexible body is presented for quadruped robot to perform the spinning gait. The spinning gait can be achieved by coordinated movement of body laterally bending and legs swing, which can improve the mobility of robot walking in the unstructured environments. The coordinated movement relationship between the body and the leg mechanism is presented. The stability of quadruped robot with spinning gait is analyzed based on the center of gravity (COG) projection method. The effect of different body bending angle on the stability of quadruped robot with spinning gait is mainly studied. For the quadruped robot walking with spinning gait, during one spinning gait cycle, the supporting polygon and the trajectory of COG projection point under different body bending angle are calculated. Finally, the stability margin of quadruped robot with spinning gait under different body bending angle is determined, which can be used to evaluate reasonableness of spinning gait parameters. |
