ABSTRACT OF THE DISCLOSURE A robot apparatus is operable in a Cartesian coordinate system for moving a workpiece gripped by a hand thereof. The robot apparatus includes a self-propelled X-axis slide unit movably mounted on an X-axis rail unit extending in the direction of the X-axis of the Cartesian coordinate system. A Y-axis slide unit extending in the Y-axis direction normal to the X-axis direction has one end fixed to the X-axis slide unit. A self-propelled Z-axis slide unit is movably mounted on the Y-axis slide unit, and a slide base to which the robot hand is attached is mounted on the Z-axis slide unit. Lead wires connected to drive mechanisms for driving the X-axis slide unit, the Y-axis slide unit, and the Z-axis slide unit pass through case members, and are housed in the X-axis rail unit and connected to a terminal box secured to an end of the X-axis rail unit. The X-axis, Y-axis, and Z-axis slide units are prevented from interfering with the respective tracks of other units during operation of the robot apparatus, so that the working envelope of the robot apparatus can be increased.
