A robot called Cube-Kun debuted earlier this month at the TEPIA exhibition in Tokyo. His sole purpose? To solve Rubix Cubes within seconds. He has a giant flat screen for a face. When you give him a Cube, he quickly registers what the six sides look like, displays that on his screen, and then figures out a solution in approximately one second. Then his hands get to work.

A puzzle-solving robot is set to take visitors to the British Toy Fair back to the future.
