Rubik's Cube Solving Robot Powered by Samsung Smartphone Aims for World Record
Published on: 13th Mar 2014
A robot powered by a Samsung smartphone is aiming to break the world record for solving the Rubik's Cube at a UK science fair this weekend.
The Cubestormer 3 robot is attempting to beat the 5.27 seconds record set by its predecessor.
The new robot employs an ARM-powered Samsung Galaxy S4 smartphone to analyze the cube and instruct four robotic hands to do the manipulations. ARM9 processors also power the eight Lego Mindstorm EV3 bricks which perform the motor sequencing and control.
"We are very confident the robot will break the record," said Dominic Vergine, head of corporate responsibility at ARM. "The new robot can think three times faster than its older brother. The older robot was using intelligence from a dual-core ARM Cortex-A9 based Samsung Electronics' Exynos 4 Dual application processor in a Samsung Galaxy S2 smartphone. 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."
Cubestormer 3 is the result of effort in their spare time over 18 months by co-designers David Gilday, a principal engineer at ARM, and Mike Dobson, a security systems engineer for Securi-Plex. The new design features upgraded mechanics including a precision independent braking system that will bring significant speed benefits. The software has also been optimized to take advantage of the increased mechanical flexibility as well as the compute power gains.
"The record-breaking attempt is a bit of fun for us," said David Gilday. "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. We're already seeing robot technology deployed widely in the manufacturing industry but there is now potential for robots to cope with disruption."
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. With the amount of solution possibilities running to 278 digits, it is a highly complex task. It will be taken on by his MultiCuber 999 robot, based on a Samsung Galaxy S3 smartphone powered by an Exynos 4 Dual application processor.
If they are successful, the new times will all be entered in the 2015 Guinness World Records book.
