In this paper, a new method for learning robotic deburring process motor skills from human skill model is presented. The skill of a human expert is obtained by using the human skill model. This model is implemented in robot control systems that make robots imitate human skills in deburring process tasks. Based on deburring process, family of basic pattern motions are listed by identifying the movement in the task (e.g. circular, straight line and sharp corners). These motions depend on a number of complex parameters; therefore, it is hard to fit a completely mathematical model to the process. By inspecting the movements of the human expert in task and analyzing these movements, the dynamic movement primitives are examined using an ordinary differential equation. In this paper, the standard method of Dynamic Movement Primitives (DMP) that would help extracting the trajectory for human interaction behaviors without using its explicit model, is modified to extract human expertise to provide a more accurate approximation of the robotic deburring process tasks. The experiments are conducted on haptic device, in which the robotic deburring processes on workpiece are imitated and the results are used as primitives to accomplish automatic deburring on the workpiece.
