ABSTRACT:
A robot assembly includes a support for mounting at least two arm portions and a wrist portion about an upright axis. The wrist has three axes of movement that are mutually perpendicular, and they are controlled by a single motor through an arrangement of electromagnetic clutches and gears so that one motor controls movement about all three axes of movement of the wrist. Additionally, gear drives are used for other movements on the robot arm to provide movement about seven independent axes in the arrangement shown with only two drive motors.
