Rubik's Cube Solver

We develop a Rubik’s cube solver that uses computer vision techniques to detect and analyze the colors on each face of the cube and then generate a sequence of moves to solve it.

Installation

Python 3 must be installed, and the following libraries are required:

• NumPy
• OpenCv
• Kociemba

How to run

python3 main.py

How to use

• Run the script, and it will initialize the camera to capture the Rubik's cube.

• Hold the Rubik's cube in front of the camera and click on a square of each color in the requested order using the mouse.

• Following that, ensure that each face is detected and highlighted in this order and orientation:

  
  1. Begin with any side facing the camera (U 1).
  2. Show the face on your left (R 2);
  3. Show the front face (F 3);
  4. Show the bottom face (D 4);
  5. Show the right face (L 5);
  6. Finally, show the back face (B 6).

• Once all six faces are detected, the solution will be displayed, and the steps to solve the Rubik's cube will be shown in real time. You have to show the F face in the orientation you showed before for the solution to be shown correctly. You must first show the F face in the correct orientation so that the solution is presented correctly.

• If you've done the steps above correctly, you should have your cube solved.

Troubleshooting

• If the camera is not detected or the script encounters any issues, check the camera connection and make sure the required libraries are installed.

• If the cube is not detected and highlighted, you will probably need to re-run the calibration process or change the Lab color ranges in main.py in the showPixelValue function.
