A rotary union connector is disclosed that may be used with a robot arm having a drive member. The connector may have an outer housing and an inner cylinder. The inner cylinder may be fixedly mounted to the drive member for rotation about a central longitudinal axis. The inner cylinder may be mounted for rotation within and relative to the outer housing. The inner cylinder may have a first vacuum channel, and may be adapted to be fixedly mounted to an end effector. The outer housing may have a first vacuum channel and a first vacuum opening for connection to a vacuum supply line to supply vacuum to the first vacuum channel in the outer housing. The vacuum channel in the outer housing may also be in vacuum communication with the first vacuum channel in the inner cylinder. The first vacuum channel in the inner cylinder has an opening for communicating vacuum from the opening to the at least one suction cup of the pick up member. When the drive member is rotated, the inner cylinder and end effector will rotate about the axis with the outer housing remaining substantially stationary in rotational movement.
