CubeStormer II is controlled by four Lego NXT ‘bricks’ that communicate via Bluetooth with a Samsung Galaxy SII smart phone. A special app on the phone takes a picture of the cube, solves the puzzle virtually, and then relays the solution to the Lego robot. From click to finish the whole process takes just seconds."
