Sub1 – Der Weltrekord haltende Roboter löst den Rubik Cube in unter 1 Sekunde

Die schnellsten Menschen lösen einen Rubik Cube in unter 5 Sekunden, was schon ziemlich unglaublich ist. Der Sub1 Roboter braucht dafür unfassbare 0,637 Sekunden. Bisher allerdings kein Grund für uns Menschen neidisch zu werden, der Sub1 kann sonst nämlich nix ;)

Prior to the world record attempt a WCA-conform modified speed cube was scrambled with a computer generated random array and positioned in the robot. Once the start button was hit two webcam shutters were moved away. Thereafter a laptop took two pictures, each picture showing three sides of the cube. Then the laptop identified all colors of the cube and calculated a solution with Tomas Rokicki’s extremely fast implementation of Herbert Kociemba’s Two-Phase-Algorithm. The solution was handed over to an Arduino-compatible microcontroller board that orchestrated the 20 moves of six high performance steppers. Only 887 milliseconds after the start button had been hit Sub1 broke a historic barrier and finished the last move in new world record time.

Needing several hundreds of working hours to construct, build, program and tune Sub1, it is the first robot that can independently inspect and solve a Rubik’s Cube in under 1 second.

The world record has been approved by Guinness World Records on 18-Feb-2016.

0.637 seconds – a new Rubik’s Cube machine world record!
