Lego NXT Rubik Cube Solver

22

 

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."

  2. I never learned to do the Rubik Cube, but I have to admit… that’s cool!

    Good Luck!

  3. There isn’t allot to compute, all the NXT has to do is perform a number of so-called “algorithms” depending on the state of the cube and these algorithms solve it. There are only about 8 move patterns which you have to remember to solve it so no calculations are really needed.


  4. There was even a non-NXT Rubix-cube solving Mindstorms robot.





  9. now it just has to work faster and it may win a record…



  11. One of the coolest hacks I’ve seen in a long time. You’re right, the ability to solve the cube is most impressive with the NXT.






  16. NXTs are also bluetooth, a laptop could still be controlling it.


  18. Holy crap, that’s amazing!

    The best thing I ever built out of lego was a giant tower, which fell over…

    Doesnt really compete.
