Video: Fastest robot to solve a Rubik’s cube record falls again as German engineer takes title

Incredible footage has proved a machine created by engineer Albert Beer (Germany) is the new Fastest robot to solve a Rubik’s cube ever, after it deciphered the famously difficult puzzle in just 0.887 seconds - breaking the previous record-breaking robot’s time of 0.9 by a fraction.

 

The official Guinness World Records title attempt took place at the Cubikon Store, in Munich, Germany last month.

 

 

In comparison, the record for the Fastest time to solve a Rubik’s cube by a person is 4.904 seconds, which was achieved by teenager Lucas Etter in November last year.

 

Beer’s robot is named Sub1 and uses two webcams which capture the arrangement of all six sides of the cube. (These were shuttered before the timing started for the record attempt.)

 

The robot then uses Tomas Rokicki's extremely fast implementation of Herbert Kociemba's Two-Phase Algorithm to determine the fastest way to unravel the cube.

 

 

An Arduino-compatible microcontroller board orchestrated the 20 moves of six high performance steppers, which rapidly turned each side of the cube.

 

The cube met all WCA (World Cube Association) standards.

 

Previous record holders: Mike Dobson and David Gilday's Cubestomer 3 held the record of 3.253 seconds until October 2015 when it was broken by Zackary Gromko with 2.39 seconds - Video here. Then a new record was confirmed for Jay Flatland and Paul Rose with 0.9 seconds just weeks ago - Full story here.
