Samsung Galaxy S 4 powers record smashing Rubik’s Cube robot solver

If you think that today's smartphones can do almost anything except power LEGO-constructed robots to solve Rubik's Cubes at breakneck speed, think again. With a new world record to prove it, Samsung is boasting of the capabilities of its Galaxy S 4, particularly the octa-core Exynos 5 Octa processor that runs the show.

The CUBESTORMER III, the brainchild of ARM engineeer David Gilday and Securi-Plex engineer Mike Dobson, broke the Rubik's Cube world record last week by solving the popular puzzle in just 3.235 seconds. They actually broke their own record, since they CUBESTORMER II held that title last year with 5.27 seconds under their belt. In comparison, the fastest human to perform the feat is Mats Valik, with a record of 5.55 seconds under his belt in 2013.

Aside from the engineering that went into the design of the LEGO robot's mechanisms, much of the success lies in the beating heart of the robot, the Galaxy S 4 and its Exynos 5 Octa chip. The Galaxy S 4's camera is used to capture a clear image of the current state of the Rubik's Cube. The rest, and the brunt, of the work is then passed on to the processor, which analyses the image and performs the calculations needed to be undertaken to solve the puzzle, all under the span of a few seconds. The robot's creators credit the fast performance of the processor, as well as the large RAM of the smartphone, to have been essential to this record-breaking attempt.

Another Exynos-powered robot was present to set a record, this time on a 9x9 Rubik's Cube. This time, ARM's Multicuber 999 was powered by an Exynos 4 Quad inside the Galaxy S III. The robot managed to solve the puzzle in 34 minutes and 25.89 seconds. That may look nothing compared to the CUBESTORMER III, but this is also something that has never been been performed before by a robot.

    That’s a 3 x 3 Cube and not 9 x 9. :)
