Friday Fun: Solving a Rubick’s Cube with LEGO

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

    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

    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.
