Lego Robot that can solve a Rubik’s Cube


Three things I like, Robots, Rubik’s Cubes and Legos. So I was overjoyed when I saw this movie by modusbeke of his Rubik’s Cube solving Lego robot. According to modusbeke:

  • The robot is controlled by a PIC18 microcontroller
  • It’s not connected to the computer and there were no NXT pieces used, everything is controlled by one single microcontroller
  • It’s using an optimized ‘pogobat’ method, and finds the solution in 83 steps, averagely (max 124 steps)
  • Custom made color detector circuit, using fuzzy logic
  • 4 DC engines controlled with H-bridges and PWM signal
  • 97×67 pixel color graphic display

You have to see it to appreciate it.
