This robot can solve a Rubik’s Cube in .38 seconds


Created by Ben Katz and Jared Di Carlo, the project uses set of 6 Kollmorgen ServoDisc U9-series motors and 2 Playstation Eye cameras. The contraption reads the cube, solves it, and then slams the thing around in seconds.

The team also used a unique AND board that ensured that each motor would turn on and off independently, a feature that is necessary to ensure the entire thing doesn’t explode if the motors were to actuate at the same time. It then uses the min2phase algorithm to solve the cube in about 21 moves. They could even make the thing slightly faster with a bit of tweaking.

And there you have it: the technical feat of 2018. As someone who grew so frustrated with my Rubik’s Cube that I peeled off the stickers and told my Mom I solved it myself, hats off to Katz and Di Carlo. Now Elon Musk just has to solve a Rubik’s Cube in space to cap off an already exciting year.
