A method of correcting and playing back positional instruction data in a robot which performs the teaching by moving an arm or wrist axis constituting a robot body and recording its locus at intervals of a predetermined time or a predetermined moving distance corrects positional data recorded after the completion of the teaching onto a predetermined pattern such as a straight line or a circular arc and plays back the corrected positional data. Further, the method corrects the positional data onto the predetermined pattern before the beginning of the playback previously and records the corrected data.
