As a new development branch in the field of robotics, bionic robot is based on the development of robotics and bionics. The prerequisite for its emergence and existence is that biology has evolved through long-term natural selection. Bionic robot is the use of all kinds of machine, electricity, liquid, light and other organic and inorganic components match the function body formed by the movement mechanism and the behavior way, mode of perception and information processing, control and coordinate calculation inference, energy metabolism and material structure has the characteristics of advanced life forms to complete all kinds of complicated task of robot system.
