The most impressive part of this Lego NXT Rubik Cube Solver is that the NXT module does the computing that solves the cube! I wouldn’t have thought that would have been possible without having a PC do the calculations.

Video after the jump.

"Tilted Twister solves Rubik’s cube fully automatically. Just place the scrambled cube on Tilted Twister’s turntable. An ultrasonic sensor detects its presence and starts to read the colors of the cube faces using a light sensor. The robot turns and tilts the cube in order to read all the faces of the cube. It then calculates a solution and executes the moves by turning, tilting and twisting the cube."
