Robot plays ping pong with Ding Ning (2016 Olympic champion)

This was cooler than the running events to me for 2 reasons: Its alternating between forehand and backhand When they placed the paddle in its hand, that precise paddle orientation and position couldn't have appeared during training since I doubt the robot hand can perfectly grasp the paddle in the same orientation/position every time. This suggests this robot was trained to be able to generalize to some range of paddle orientations and positions in its hand, and this is especially important because in ping pong, tiny differences in orientation/position of the paddle can decide whether the ball hits the table or the ground
