The structural design, simulation analysis and parameter optimisation of the cheetah robot's leg components

Abstract

The design and analysis of the cheetah robot's leg is directly associated with the bionic shape, bionic structure, bionic function and the bionic materials, even the bionic control. Adopting the essences of the cheetah skeleton system, we finish the design, the simulation and the optimisation of the bionic cheetah leg. After the strength, stiffness, stability, reliability and the durability are ensured, the basic shape and size are constructed according to the properties of functions and connections. After applying load, a finite element analysis (FEA) is carried out. According to the results of FEA, the design is well optimised. The methods described herein combines the advantages of CAD and CAE technology, which can significantly enhance not only the accuracy, rationality and speed during the design of the bionic cheetah robot's leg, but also the level of optimisation of biomimetic robots.
