This video shows the manipulator dribbling a ping-pong ball, spinning a pen, throwing a ball, tying knots, grasping a grain of rice with tweezers, and tossing / re-grasping a cellphone!
Based on the video, the hand uses high-speed actuators with harmonic drive gears. The hand can close in 1/10th of a second! Personally, I find the tweezers grasping the grain of rice the most entertaining — very anthropomorphic.
