Abstract: A teaching device for performing teaching operations of a robot includes a selection unit which, during a teaching operation or after a teaching operation of the robot, moves among a plurality of lines of a program of the robot and selects a single line, an error calculation unit which calculates, after the robot has been moved by hand-guiding or jog-feeding to a teaching point which has already been taught in the selected single line, a position error between the teaching point and a position of the robot after movement, and an instruction unit which instructs to re-teach the teaching point when the position error is within a predetermined range.
