The record for fastest Rubik's Cube completion is impressive, just 4.69 seconds as of September 2017, but the record held by a robot is hard to believe—even when you see it with your own eyes.
Blink and you might miss the feat accomplished in the video below, shared by The Kid Should See This. In it, a robot transforms the jumbled kid's toy into a cube with perfectly uniform sides in just 0.38 seconds, a time that earned the machine the record for fastest Rubik's Cube completion by a robot in March 2018.
The secret to the robot's remarkable Rubik's Cube skills is a smart software that can determine the color of each square from webcam images. From there, it calculates the exact movements necessary to produce a perfect cube, and then it makes them in a fraction of a second.
The biggest issue for the team wasn't engineering the robot to be super fast: It was making sure the cube didn't fall apart as it was being scrambled. To their surprise, they only destroyed four toys during the process.
