A German engineered robot shattered its own Rubik's cube world record, completing the puzzle in a little more than half a second.

The Sub1 robot, developed by engineer Albert Beer, set a new Guinness World Record for "Fastest robot to solve a Rubik's Cube" by solving the puzzle in 0.637 seconds.

Now known as Sub1 Reloaded, the robot shaved off more than a quarter of its 2016 record time of 0.887 seconds after receiving a new Infineon processor chip.

The process of solving the puzzle begins when a computer receives two photos of the Rubik's Cube then identifies the color of each piece and uses Tom Rokicki's implementation of Herbert Kociemba's Two Phase Algorithm to determine the quickest solution.

An Arduino-compatible Infineon AURIX microcontroller board then operates the robot's six mechanical arms, allowing it to complete the puzzle in 21 moves.
