The motion pattern and leg structure of living things in nature have been gradually applied to the fields of mechanical motion and robot motion, and many robots use leg structures similar to a number of arthropods such as spiders, ants, etc. They possess efficient foot motion and are of particular interest in the field of robotic development.
Due to the special leg structure of the multi-foot walking robot, proper driving power needs to be used, and a steering engine and hydraulic pressure are commonly used as drivers. The micro multi-legged walking robot is limited by the size and the load of the whole machine, and a motion execution mechanism with higher power density and lighter weight needs to be selected. The miniature steering engine is used as an actuating mechanism, and the miniature steering engine has the advantages of simple control and concise wiring. However, in the existing execution mode of the miniature steering engine, the execution angle range is limited to 0-180 degrees or 0-270 degrees, the mechanical position of the steering engine support limits the actual angle movement range to be smaller, the limit position is not easy to reach, the phenomena such as shaking and the like which are not beneficial to controlling the posture often occur, the movement range of the robot is limited to a certain extent, and the control of the robot is influenced.
