Study on Mechanics Structural Synthesis of Six-Legged Walking Robot with Parallel Leg Mechanisms

Abstract

In order to use the parallel leg mechanisms in the six-legged robot, a six-legged walking robot with parallel leg mechanisms was presented. A six-legged walking robot type synthesis method based on screw theory was proposed. By this method, the paper carried on the structural synthesis of whole robot and the parallel leg mechanisms. 2-UPS&UP mechanism was chosen as the leg mechanism of the six-legged walking robot. 2-UPS&UP mechanism had been proven not to be an instantaneous mechanism by the displacement manifold theory. The specific structure of the six-legged walking robot based on2-UPS&UP mechanism was designed. These studies laid the theoretical foundation for further study of the six-legged walking robot. This type synthesis method could be used for the design of other multi-legged walking robot.
