Ah Rubik's Cube — that mathematical contraption designed to get student thinking was a phenomenon 20 years ago, and it's still finding ways to impress people today. Solving a Rubik's Cube quickly is one way to impress, and Cube-Kun, a robot designed specifically to solve the puzzle, can do it in seconds.

Created for the TEPIA exhibition in Tokyo, the robot scans the Cube, and computes the solution in approximately one second. After that, Cube-Kun's robot hands go to work spinning the sides until solved. It's kind of a cheat that the robot is solving a mathematical problem as I've seen real people do it with brain power in less than 30 seconds. Oh well, sure beats breaking the thing apart and reassembling — not that I would know anything about that.
