The Cubestormer 3 robot which uses ARM® processor technology smashed the Guinness World Record™ title for solving a Rubik’s® Cube, recording a time of 3.253 seconds at the Big Bang Fair in Birmingham, UK. The record bests the existing time of 5.27 seconds set two years ago by the same team. The Cubestormer 3 is built with Legos and powered by a Samsung Galaxy S4 (with the ARM® processor). The smartphone analyzes the cube and calculates the optimal moves and solves the challenge with 4 robotic arms made by LEGO Mindstorms EV3. There are 43 quintillion (43 followed by 18 zeros) ways to scramble a Rubik's Cube, which makes the computing power impressive. But more impressive is the coordination, dexterity, and the motor functions required for the Rubik's Cube to be solved so quickly.

The record for a human is currently 5.55 seconds.
