PURPOSE:To simplify the correction of a teaching point of an industrial robot by performing the re-teaching of one of teaching points to be corrected and correcting the teaching data on other teaching points based on the deviation amounts obtained before and after said re-teaching point. CONSTITUTION:When teaching points K1, K2 and K3 are shifted by the same distance in the same direction and changed to the teaching points T1, T2 and T3 respectively, the robot main body is actuated at the point K1. Then the re-teaching is given to the point T1 after a correction mode is set. The difference of teaching data is obtained between the points T1 and K1 in the form of a deviation amount k1. This deviation amount is written to a work memory. Then the robot is moved to the point K2 and the amount k1 is added to the teaching data on the point K2. Thus the teaching data k2 is obtained and written to the area where the teaching data on the point K2 is stored. Then the robot is moved to the teaching point shown by the data k2 and then to the point K3. Thus the teaching data k3 is obtained after the point K3 is corrected.
