Arc tracking on an eight-axis robot system

Arc tracking is a significant function in welding robot applications. In this paper, we present an eight-axis robot arm system, and propose an arc tracking on this system, including signal collection, process, and offset derive. Moreover, we establish a kinematics modeling of sine weaving, and offset compensate models, which can compensate actual offsets to the welding process, and experiments show that they can be satisfied to the industrial needs.
