The inventors of the Rubik’s Cube-solving robot have achieved their goal of setting a new world record for solving a Rubik’s Cube in the machine category of the Guinness World Records, according to Gizmag.

But their crown may be short-lived, with another robotic contender appearing to have beaten their time – although unofficially, for the moment.

Last November, a machine created by American student Zackary Gromko solved the multicolored cube in just 2.39 seconds. But just a few months later the record has been cut in half.

Two friends from Kansas, Jay Flatland and Paul Rose, made their tilt at the official world record with their machine. With a Guinness World Record official in attendance, their machine solved a Rubik’s Cube in just 0.9 seconds, according to Lenta.ru, a Moscow-based online newspaper.

Flatland and Rose stole the crown from Gromko after just a couple of months, but they may lose the title even faster. Sub1, a machine created by industrial engineer and economist Adam Beer, is now throwing its circuit board into the ring. 

Beer says Sub1’s attempt involved the use of a World Cube Association (WCA)-conform modified speed cube that was scrambled by a computer generated random array before being positioned in the robot. As soon as the start button was triggered, shutters were removed from two webcams, which each captured an image of three sides of the cube. These were relayed to a laptop, which identified the various colors and calculated a solution using “Tomas Rokicki’s implementation of Herbert Kociemba’s two-phase algorithm.”

Once the solution was reached, it was forwarded to an Arduino-compatible microcontroller board that swung six high-performance steppers into action. After 20 moves and 0.887 seconds, it was all over.
