Tilted Twister- a Lego Mindstorms robot that solves Rubik’s cube

Created by Hans Andersson, the 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. It then calculates a solution and executes the moves by turning, tilting and twisting the cube.



  • Scanning the cube: 1 minute
  • Calculating a solution: 20 – 40 seconds
  • Executing the moves: 1 – 5 minutes. Average 4.5 minutes (60 faceturns)

Average total time: 6 minutes

Build your own Tilted Twister

You can find building instructions and programs here.

I built one of these but I have not gotten it completely working yet. It keeps slipping when it is solving the cube and getting stuck. If you have any suggestions, leave a comment.
