This is Janken, a Rock, Paper, Scissors robot that will beat you 100% of the time. It uses a high-speed vision system to surpass the abilities human beings.


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, but it all happens so fast that it’s more or less impossible to tell that the robot is waiting until you commit yourself before it makes its move, allowing it to win 100% of the time.

Machine vision is almost here, and it will change everything. I hope we get a version of the future that looks more like Star Trek than like this, but I guess that depends on us more than the robots.
