Abstract
An end effector for a robotic arm. The end effector includes an angle compensator for attaching a suction cup, a vacuum control valve, a vacuum generator, a level compensator, and an extension tube which are sequentially connected along a central axis and in fluid communication, and a vacuum sensor connected to the vacuum control valve for measuring vacuum, a proximity sensor attached to the extension tubefor determining position of the level compensator. The vacuum is generated when compressed air passes the extension tube, the level compensator and the vacuum generator along the central axis. The level compensator provides compensation along the central axis.
