Zusammenfassung:A teaching apparatus is provided with an arm-side position sensor attached to arms, a dummy wafer placed on a stage, a dummy-wafer-side position sensor attached to the dummy wafer, and a signal receiver configured to receive a position signal from the arm-side position sensor to determine a position coordinate of the arm-side position sensor, and receive a position signal from the dummy-wafer-side position sensor to determine a position coordinate of the dummy-wafer-side position sensor. A control part, based on the position coordinate of the dummy-wafer-side position sensor, calculates a position coordinate of the arm-side position sensor when the arms hold the wafer, and moves the arms such that the arm-side position sensor moves to the calculated position coordinate.
