Design of Leg Structure of Quadruped Robot Based on GF Set

Aiming at the design of the leg structure of the quadruped robot, this paper introduces the G_F set theory. By pre-setting the dimension of the base plate, the G_F set of its branch chain is reversed, and then the leg structure of the robot is constructed from the geometric conditions and the characteristics of the branch chain. Finally, the obtained robot leg structure and the base plate are assembled to obtain the assembly drawing of the quadruped robot, and then the physical image of the quadruped robot is obtained according to the assembly drawing of the quadruped robot.
