The Android App running on the Droid mobile phone uses the phones camera to take pictures of each face of the cube and sends the solution to the LEGO NXT controller via Bluetooth and is able to solve Rubik’s Cube in just 24 seconds. [via Microsiervos]
There is also LEGO MultiCuber 5x5x5, the world’s first LEGO robot to solve a 5x5x5 Rubik’s cube. It is so named because it can solve not only the 5x5x5 cube, but also cubes of other dimensions. Cubes larger than the original 3x3x3 Rubik’s cube require a mechanism that is capable of turning multiple layers rather than just the faces of the cube. Happy Puzzling!
