Teaching position correcting apparatus and teaching position correction method

A teaching position correcting apparatus (1) corrects plural teaching point positions of a robot (2) in a robot operation program, by sequentially moving the robot (2) to each of the plural teaching points and by sequentially reading a current position of the robot (2) at each of the plural teaching points. The teaching position correcting apparatus (1) includes: a position correction amount calculating means (11a) that calculates a position correction amount (A), based on corrected teaching point positions and teaching point positions before correction; and a corrected-position calculating means (11b) that calculates corrected positions of teaching point positions before correction out of the plural teaching points, based on the position correction amount (A). At the time of moving the robot to uncorrected teaching points, a moving means (15) moves the robot to corrected positions of the teaching point positions before correction. Based on the above operation, even when a posture change of the robot is large, teaching point positions in the operation program can be corrected accurately in short time.
