Hans Andersson’s Tilted Twister is a Rubik’s Cube solver built from only parts available in the LEGO MINDSTORMS NXT retail set. Here’s what Hans says:
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.
