Abstract
Provided is a teaching position correction device including a vision sensor attached to a tip end of an arm of a robot; a measurement unit measuring a three-dimensional position of the tip end of the robot when the sensor is arranged at a predetermined position with respect to each of reference points provided on an object or a holding device and not arranged on one straight line; and a calculation unit calculating relative positions of the reference points based on the measured three-dimensional position while the sensor is translated, where a teaching point position in an operation program of the robot is corrected in such a way that a change in relative positions of the robot and the holding device is compensated for, based on the relative positions of the reference points calculated before and after relocation of at least one of the robot and the holding device.
