The current record of 5.27 seconds was set just over two years ago by its predecessor CubeStormer II.
The robot called Cubestormer 3 was built by co-designers David Gilday, a principal engineer at ARM, and Mike Dobson, a security systems engineer for Securi-Plex.
“The record-breaking attempt is a bit of fun for us. Our real focus is to demonstrate what can be achieved with readily-available technology to inspire young minds into taking a greater interest in science, technology, engineering and mathematics,” said David Gilday.
“We’re already seeing robot technology deployed widely in the manufacturing industry but there is now potential for robots to cope with disruption. You can easily imagine a robot able to deal with minor surgical procedures or perhaps even a Michelin-starred robot chef?” said Gilday.
The smartphone’s processor analyses the cube and instruct four robotic hands to do the manipulations.
The older robot used a dual-core ARM Cortex-A9 based Samsung Electronics’ Exynos 4 Dual application processor in a Samsung Galaxy S2 smartphone.
This weekend Cubestormer 3 will use a Galaxy S4 equipped with an Exynos 5 Octa application processor with an eight-core ARM big.LITTLE implementation featuring four Cortex-A15 and four Cortex-A7 processors.
There are also ARM9 processors in the eight Lego Mindstorms EV3 bricks which perform the motor sequencing and control.
“The new robot can think three times faster than its older brother,” said Dominic Vergine, head of corporate responsibility at ARM.
Cubestormer 3 is expected to draw equal attention on-line and from the crowds expected at this year’s Big Bang Fair. Guinness World Records editor-in-chief , Craig Glenday, will be present to adjudicate at the event.
Alongside the fastest robot to complete a Rubik’s Cube attempt, David Gilday is looking to set two further world records with other ARM-based robots. The first, for the quickest completion of a 4x4x4 cube using his MultiCuber 3 robot based on a Huawei Ascend P6 smartphone based on Hisilicon’s K3V2E processor. He will also attempt to set a time for completing a 9x9x9 cube, the first time a robot has attempted this.
