Structure design and performance analysis of a new buffering leg

The leg structure is an important component to achieve good buffering performance for bionic locust jumping robot, so the structure design and analysis of the leg has important significance. In order to achieve the better landing buffering performance, a new buffering leg is designed based on the physiological structure of the locust's leg and the structure of bionic series buffering leg. After the kinematic and mechanical property analysis for the buffering leg, the structure parameters are analyzed and optimized according to the buffering performance evaluation principle, and the buffering performance of the new buffering leg and bionic series buffering leg, which are in the optimal state, is compared and analyzed. Compared with the bionic series buffering leg, the amplitude of the force that the new buffering leg is subjected to from the ground reduces by 25.3%, and the energy storage capacity increases by 34.6%. It provides a basis for the development of robot and other landing mechanism.
