A New Design of Three-Legged Robot of Mechanical and Control System

Abstract

A new type of three-legged robot design scheme is proposed and the movement control of it is studied in this paper. Spatial crank rocker mechanism (RSSR) is used to will the motor rotation into a leg swinging in mechanical design. Advanced reduced instruction-set computer machines (ARM) chip, wireless communication module and magnetic encoder are used in controller design. Proportional and differential (PD) closed loop control arithmetic is used to realize the control of the robot. The robot realizes the movement of straight walk, curve walk, turning in situ, jumping and so on. It has a broad application prospect.
