Analysis and optimization of the structure of robot arm

In this paper, a three-degree-of-freedom robot model is established to solve the problem of unstable structure of the manipulator. Using the finite element method, topology optimization, the key component of the robot, the rear arm. This paper carries out static analysis, lightweight design, to verify its stiffness and strength. For the improved arm structure, the structure is more stable, reasonable and lighter.
