That arm is the KUKA Light Weight Robot (LWR) Arm, which was developed by the German Aerospace Agency (DLR) and called the DLR III LWR [1]. It can move _MUCH_ faster than in the video. It likely moves that slow for the safety of the human and itself -- it costs ~$150k and the high-speed movements create a lot of momentum. Incidentally, this was the same arm used in the "knife-stabbing experiments."
