Lego robot Rubik's Cube: Watch as robot solves Rubik's Cube in record 3 seconds

A Lego robot takes on a Rubik's Cube, and what may take you or I hours to solve, this suped-up Lego-bot armed with lighting fast gears and a smartphone timer blew through in record-breaking time.

“If you were never able to solve a Rubik's Cube without peeling off the stickers or prying it apart with a butter knife, you're really going to hate this robot,” shared CNN on Monday.

It’s called the Cubestormer 3, and the Lego built robot solved a jumbled up Rubik's Cube puzzle in just 3.253 seconds — breaking the Guinness World Record by more than two seconds.

The NY Daily News explains how it works:

Unveiled at the Big Bang Fair in Birmingham, UK, the Cubestormer 3 is constructed from Legos, the modular children's building-block toy, but uses a Samsung Galaxy SIV smartphone with a special ARM chip addition as its brain. It analyzes the muddled up Rubik's Cube and powers each of the robot's four “hands,” which spin the cube until all sides are in order.

The Cubestormer 3 was built by engineers David Gilday and Mike Dobson, and their latest creation – which took 18 months to develop – surpassed the previous Lego robot record 5.27 seconds, set by the Cubestormer 2, which was also built by Gilday and Dobson.

“We knew Cubestormer 3 had the potential to beat the existing record but with the robot performing physical operations quicker than the human eye can see there's always an element of risk,” said Gilday. “In the end, the hours we spent perfecting the robot and ensuring its motor and intelligence functions were properly synchronized paid off. Our big challenge now is working out if it's possible to make it go even faster.”

In case you’re wondering, the best human time to solve a Cube was 5.5 seconds, set by Mats Valk of the Netherlands last year. Watch the video.

According to its makers, any Cube permutation can be solved in 20 moves or less.
