Thanks to Yaskawa, a multinational company with roots in Japan that specializes in servos and motors for servos, the answer is yes. For their "Yaskawa Bushido Project", the company joined with Isao Machii, a master of the Iaijutsu sword fighting technique. Side by side, Machii and a Yaskawa Motoman MH24 robot arm completed five challenges, at first slicing their way through flowers, fruit, and peapods. They then rapidly cut a thousand times into practice targets. At the end of that last trial, Machii looks exhausted, but his unfeeling machine counterpart is as ready to go as ever. It's a good thing it can't walk.
