A robot has beaten the human record for the fastest-ever solving of a Rubik’s Cube by 400 per cent. It took this homemade robot 1.019 seconds, compared to the human record of 4.904 seconds.

The robot is made of stepper motors in 3D printed frames that are drilled directly into the Cube itself. The motors are controlled by an Arduino, which turns the Cube so fast, it’s essentially a blur. The robot “sees” the Cube through 4 webcams connected to a computer running Linux, where an algorithm computes the quickest way to solve the puzzle. Between each attempt, the webcams are covered up and the Cube is manually re-scrambled. The current human record is held by 14-year-old Lucas Etter of Lexington, Kentucky who set the record in November 2015.

It took Erno more than a month to solve his own puzzle right after he created it. If you want to try it the old school way, here are our top tips. [embedded content]
