Animals or insects can walk or run more elegant and advanced than any other legged mechanical models. They can move on a variety of terrain conditions since they have a distinct ability to adapt to varying conditions by using strictly coordinated leg mechanisms. Nature has an astonishing capability. They continuously have modified their body structures and living patterns, which makes it possible to survive and still continue their developments. Structural and locomotive characteristics of four-legged animals are copied and modelled from the mechanical view point, as body and links. The model is the robot, having 4-legs. Under the given structure and the locomotion conditions, the total energy to complete one cycle is calculated and finally suggested the optimal locomotive conditions.
