Abstract: To facilitate teaching work in an orthogonal three-axis playback measuring robot having an orthogonal three-axis actuating mechanism including a main arm; a multijoint arm including at least one rotary arm and one pivotal arm attached to an end of the main arm; and a probe attached to an end of the multijoint, in particular, a number of manipulation switches are arranged on an end of the main arm of the actuating mechanism and on outer surfaces of the rotary and pivotal arms of the multijoint arm in such a way that each pair of two switches are so arranged as to correspond to two opposite straight, rotary or pivotal movement directions of each of the above various arms.
