Solving a Rubick’s Cube with LEGO and popsicle sticks

The user enters the cubes state into a python GUI, which the solves the cube using the beginners layer by layer method. It then sends the solution to the Arduino via (usb) serial, which then solves it.

Rubik’s Robot So Fast It Looks Like a Glitch in the Matrix

https://hackaday.com/2018/03/12/rubiks-robot-so-fast-it-looks-like-a-glitch-in-the-matrix/

From Ferraris to F-16s, some things just look fast. This Rubik’s Cube solving robot not only looks fast, it is fast: it solved a standard cube in 380 milliseconds. Blink during the video below and you’ll miss it — even on the high-speed we had trouble keeping track of the number of moves this solution took. It looked like about 20.

Algorithmic Solution to Solve Rubik’s Cube in Only 20 Moves

https://www.eeweb.com/profile/max-maxfield/articles/algorithmic-solution-to-solve-rubiks-cube-in-only-20-moves

The Rubik’s Cube has only six faces, each presenting only nine cubelets, but the end result is to offer a mind-boggling number of permutations, only one of which embodies the desired solution.

Although the standard Rubik’s Cube has only six faces, each presenting only nine cubelets, the end result is to offer a mind-boggling number of permutations, only one of which embodies the desired solution.

Wow! That sure is a lot of permutations. So, you can only imagine my surprise when I ran across this video, which purports to offer a universal solution that can solve the cube from any initial scrambled condition in at most 20 moves using the following algorithm: L R2 B L’ R U2 F2 L B D U2 B L’ R2 B2 L’ D2 U L’ B2 U2 R2 B D2.

Self-Solving Rubik’s Cube Robot!

This self-solving Rubik’s Cube robot was one of the coolest things we saw at Maker Faire 2019. Its creator Takashi Kaburagi shows us how it works and we take a peek beneath the tiles to see its robotic core. Watch it come alive and perform a solve!

Another Rubik’s Cube Robot Is Simple But Slow

https://hackaday.com/2022/06/13/another-rubiks-cube-robot-is-simple-but-slow/

[AndreaFavero] says that the CuboTino emphasizes simplicity and cost-savings over speed. However, solving the puzzle in about 90 seconds is still better than we can do. The plucky solver uses a Pi and a camera to understand what the cube looks like and then runs it through a solver to determine how to move.
