Forcefree control with velocity consideration under assigned locus is proposed for articulated robot arm. The tip of the robot arm is moved on an objective locus according to the tip velocity. Then, the direction of tip velocity, which corresponds to exerted force, is modified to the tangential direction of assigned locus. Contouring work of articulated robot arm is, therefore, carried out with forcefree control. Effectiveness of the proposed forcefree control is assured by simulation and experimental work on a two-degree-of-freedom articulated robot arm. And applications of forcefree control with assigned locus were also discussed.
