Robots have gotten pretty good at solving Rubik’s Cube puzzles. We have already covered a bunch of world record attempts for solving this puzzle in the past. Sub1 is a robot that has managed to solve a Rubik’s Cube in 0.887. It has an Arduino-compatible micro-controller board that handles the 20 moves of six steppers.
As the developers explain, hundreds of working hours were spent to construct and program Sub1. Pretty impressive, don’t you think?
