A smartphone-powered robot has beaten the world record for solving a Rubik's Cube with a time of 3.253 seconds.
Put through its paces at last weekend's Big Bang Fair in the United Kingdom, the CubeStormer 3 roundly beat its predecessor's time of 5.27 seconds and the fastest human time of 5.55 seconds, Forbes reported.
In 2011, robot developers Mike Dobson and David Gilday used the CubeStormer II robot to beat the world record for solving a Rubik's Cube. Building their robot with Lego kits and a Samsung Galaxy S2, Dobson and Gilday set the new world record with a 5.27-second time.
The CubeStormer II marked the first time a robot had ever beaten the human record for solving the puzzle.
At the recent Big Bang Fair, Dobson and Gilday's new robot performed even faster and was powered by a Samsung Galaxy S4.
"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," Gilday said in a statement.
"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."
The Samsung Galaxy S4 is the robot's "brain," using the camera to scan the Rubik's Cube and issuing instructions to the robot's arms to solve the puzzle.
"The robot demonstrates just how fast a Samsung Galaxy S4 can think," Gilday said. "As well as working out the solution, the ARM-powered Exynos processor has to instruct the robot to carry out the moves.
"This is more complex than it seems because CubeStormer 3 uses a speed cube which allows twists before the sides are fully aligned. It means the robot is effectively mirroring the same kind of judgment and dexterity that a human speed cuber has to apply. "
