The project uses the Pi to directly solve the Rubik’s cube. The BrickPi3 takes the unsolved Rubik’s cube and the Raspberry Pi takes a picture of each side of the Rubik’s cube with the Raspberry Pi Camera. The Pi creates a text map of the color squares that shows where they are located on the cube. When it has fully mapped the cube, the Pi uses the “kociemba” python library to map out the moves needed to solve the Rubik’s cube. This information is taken by the Pi and BrickPi3 to solve the Rubik’s cube using the LEGO motors. The result: a solved Rubik’s cube. Rubix Building Solutions
Just because this kit gives you a behind-the-scenes look as to how a Rubik's Cube is made along with tips for how to solve it doesn't mean that you'll be solving it like a pro within seconds. Even the solution booklet itself says that the first step will take practice and trial by error. So this is definitely going to be more fun for kids or adults who enjoy the puzzlement of a Rubik's Cube and have the patience to build it and practice using the solving tips. But once you finally do solve it, you'll be pretty proud of yourself, and your friends and family will be impressed. Rubix Builders
Here, we're looking at the colours that aren't solved. There are 21 different cases for the top layer, but we only need a couple of algorithms to solve them all. The first thing we want to find is headlights. Only 2 of the cases don't have any headlights (one of them is if you skip this step, and the cube is already solved). For the one case without headlights, just perform the algorithm below from any angle. This is a better case because when you do the next step, the cube will be solved already.
An important thing to note is that this task is not a light one. It may require several hours of attempts. If you'd rather just solve the cube in your hand and forget about it rather than being able to solve any cube you're given, there are plenty of solvers available on the web. However, the satisfaction of holding a completed Rubik's Cube in your hand and thinking “I did that, and I can do it again” is greater than most, mainly due to the fact that the puzzle has been present in all our lives at some point. By the mid 1980's, an estimated fifth of the world's population had attempted to solve the cube. If you want to stand out and say that you can defeat the puzzle, time and determination is a large factor. Rubix Build
