A B S T R A C T Mounted upon a servo-motor-driven longitudinally-recipro- cable X-axis carriage is a servo-motor-driven laterally-recipro- cable Y-axis carriage upon which is mounted the cylinder of a lifting and swinging motor with an upstanding vertically-movable and rotatable piston rod. Mounted on the piston rod is an elong- ated fixed horizontal arm on which is journalled an elongated extensible horizontal arm rotated by a rotary actuator mounted on the fixed arm as well as advanced and retracted horizontally by a reciprocatory motor mounted on the fixed arm. Also mount- ed on said fixed horizontal arm and rotatable by a stepping mo- tor is a horizontal video camera with a narrow angle of view but high resolving power. Aligned with said video camera is an inclined reflector adjustably mounted on the outer end of said extensible arm and reflecting horizontally toward the camera vertical light rays from the workpieces underneath on a suitably- illuminated contrastingly-colored work carrier. A stationary vertical overhead video camera with a wide angle of view but lower resolving power is fixedly mounted above said work carrier and focussed thereupon. In a modification this vertical over- head video camera is mounted for stepping-motor rotation upon a servo-motor-driven laterally-reciprocable Y-axis carriage which in turn is mounted upon a servo-motor-driven longitudinally-re- ciprocable X-axis carriage above the work carrier. Mounted upon said extensible arm adjacent and behind said reflector is an article gripper stepping motor arranged to ro- tate upon a vertical axis, a workpiece gripper suspended from said arm and having parallel-moving gripping fingers opened and closed by an air cylinder mounted on said arm. The computerized electronic operating system for this device involves convention- 31 components and is described below.
