Off-line programming of Spot-weld Robot for Car-body in White Based on Robcad

Off-line programming of spot-weld robot is the future application of robotics. It could develop robot programs without the access to the robot itself and reduce the programming time required for the manufacturing process. In this paper, an approach to implement the off-line programming of robot based on Robcad with the process knowledge of car-body in White welding was proposed. Some common problems, such as motion simulation, collision detection and calibration can be solved by this approach. Finally, the off-line programming of spot-welding robots for a car's welding work-station was realized.
