June 27, 2012, 9:22 AM — In this video courtesy of IshikawaLab at the University of Tokyo, we see a janken (rock-paper-scissors) robotic system that has a 100% winning rate, mainly because the visual sensors in the robotic hand can determine the human player's move and then determine the winning hand within milliseconds. When played at full speed, it appears as if the robot is playing at the same time.
When they slow the video down, you can see that there is some time for the robot to see the move and make its move. So basically the robot is cheating.

No word yet if the robot will be able to win at Rock-Paper-Scissors-Lizard-Spock.
