Janken is the Japanese term for Rock-Paper-Scissors, the game you can play by just using hand gestures. To all who don’t know it – a scissor beats paper, paper beats rock, and the rock beats the scissors. Playing that against other people leaves you a good chance to actually win the game.

The Janken robot, on the other (robot) hand (pause for laughs), has a 100% chance to win. In the video below you can watch the third version of the Janken robot by the Ishikawa Senoo Laboratory from the University of Tokyo and see how it works. If you want to read into details you can also check their website.
