A robot movement control method, in which a robot is moved along a smooth path (10, 11) determined based on a teaching path defined to pass a designated starting point (TP4), at least one intermediate point (TP5, TP6) and a terminal point (TP7), is disclosed. The smooth path is determined so that the coincidence between the actual path for robot movement and the teaching path is assured near the starting point (TP4) or the intermediate point.
