Abstract
An acceleration generated when a tool tip of a robot moves straightly or turns a teaching point inward, is suppressed under a predetermined maximum acceleration so that the tool tip moves smoothly. From teaching point data including a moving instruction to specify a trajectory shape on the basis of a teaching point giving a reference based on which a tip portion of the robot moves, a moving speed instruction to specify a moving speed of the tip portion on the trajectory, and an allowable path error to specify a maximum value of an error between the teaching point and the trajectory, a realizable moving speed when the tip portion of the robot moves on the straight line trajectory is obtained, a deceleration rate with respect to the moving speed recorded in the teaching point data is obtained, a realizable moving speed when the tip portion of the robot passes the inside of the teaching point is obtained, a deceleration rate with respect to the moving speed recorded in the teaching point data is calculated, and those values are stored in the teaching point data. When the robot is operated, in accordance with the straight portion deceleration rate and the inward turning portion deceleration rate stored in the teaching point data, the moving speeds of the robot at the straight portion and the inward turning portion are reset.
