Kinematic Characteristics Analysis of Cooperative Welding Robot with Multiple Manipulators

Abstract

Due to the special structure of the new dual-beam laser cooperative welding robot with multiple manipulators which is used in aerospace industry. In this paper, the kinematics model of the new welding robot with multiple robotic arms is established based on Denavit-Hartenberg (DH) method. The correctness of the kinematics model of the robot is verified. The workspace of the cooperative welding robot with multiple manipulators is obtained with Monte Carlo method, which reflects the kinematic performance of the robot, and the space constraint of the welding trajectory for dual-beam laser is obtained. By analyzing the kinematic characteristic of the dual-beam laser cooperative welding robot with multiple manipulators, the stability of the robot system can be improved.
