IEEE Spectrum - A robot (from the Ishikawa Oku Lab at the University of Toyko) is unbeatable at rock, paper scissors. It's one of those high speed hands that works with a high speed vision system. And when we say 'high speed,' we mean fast enough that you can't really tell that the robot is cheating.
It only takes a single millisecond for the robot to recognize what shape your hand is in, and just a few more for it to make the shape that beats you.
