Designed by David Gilday, a principle engineer at ARM, the smartphone is powered by an Exynos 5 Octa application processor with an eight-core ARM big.LITTLE implementation.

"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 David Gilday, co-creator of the robots.
