Built by British engineers, David Gilday and Mike Dobson, the CUBESTORMER 3 robot is the current record-holder for the fastest attempt at solving the Rubik’s Cube. At the UK's Big Bang Fair, held in March of this year, the robot solved a Rubik's Cube in 3.253 seconds flat.
The third iteration of Gilday's and Dobson's puzzle-solving invention, CUBESTORMER 3 shaved more than two seconds off the former robotic world record, which happened to be held by its predecessor, named CUBESTORMER 2.
CUBESTORMER 3 is powered by a special, super-fast type of architecture for computer processors called ARM, and runs using a Samsung Galaxy S4 smartphone, plus nine different processors, all connected to eight LEGO ‘Mindstorms’, which are kits you can buy to create customisable and programmable robots.
Robert Sorokanich at Gizmodo explains how it went about solving a Rubik’s Cube:
"The smartphone brain analyses the cube's starting arrangement, then instructs four robot arms to carry out each step needed to get the cube to its solved state. Since the robot uses a speed cube, which allows twisting moves even when the sides aren't perfectly aligned, the robot hands must be amazingly precise to move so smoothly and quickly."
