Abstract: As is well known that a camel living in desert can not only better adapt oneself to the circumstance of desert but also travel on sand with better ability. This paper analyzes the camel foot structure, its locomotion and interaction between camel foot and sand. Based on bionics theory, the theory and method to design the legged vehicle foot modelled on it of camel are established. The mechanisum of legged vehicle foot mentioned above has been developed. Its performance are measured. The results of tests indicate that the legged vehicle foot modelled on it of camel can travel on sand with better performance. It makes valuable contribution to the development of legged vehicle.
