Robot Ruby solves Rubik's Cube in 10.69 seconds, still can't beat humans (video)
There are a few robots smart enough to solve a Rubik's Cube in seconds flat, but a group of students at Swinburne University of Technology think theirs may be the fastest on Earth. Their bot, named Ruby, recently mastered the puzzle in just 10.69 seconds, including the time spent analyzing the cube. To achieve this feat, the device scanned the toy with a webcam before its software processed the images to crank out a solution. According to the university, Ruby's 10-second mark smashes the current world robot record of 18.2 seconds, unofficially making it the fastest cube-solving machine on the planet. But Ruby still has a long way to go before it catches Feliks Zemdegs -- a 16-year-old Australian who solved a Rubik's Cube in 6.24 seconds and continues to carry the torch for all of humanity. Twist and turn your way past the break for the full PR and a video of Ruby in action, as well as a clip of Zemdegs showing us how the pros do it.

Robot Ruby breaks Rubik's record
The world's fastest Rubik's Cube-solving robot has been developed by students at Swinburne University of Technology.
The robot, named Ruby, can solve the scrambled puzzle in just over 10 seconds, including the time taken to scan the initial status of the cube.
It was built from scratch by six students as their final year project for the double degree in Bachelor of Engineering (Robotics and Mechatronics)/Bachelor of Science (Computer Science and Software Engineering).
"Ruby works by scanning each face of a scrambled cube through a web cam. It then uses a software algorithm to develop a solution which is fed to the high-speed robot through a real-time embedded control system," said Professor Chris Pilgrim, Deputy Dean of the Faculty of Information and Communication Technologies.
"The students' combined expertise in robotics and software engineering enabled them to construct a robot with a fast computer vision-tracking system capable of very high precision movements and timings."
The team comprised identical twin computer whiz kids David and Richard Bain, Daniel Purvis, Jarrod Boyes, Miriam Parkinson and Jonathan Goldwasser.
They are applying to have Ruby's Rubik's-solving skill recognised by Guinness World Records. The current human world record for single time on a 3×3×3 Rubik's Cube is held by Feliks Zemdegs who had a best time of 6.24 seconds at the Kubaroo Open 2011.
As at October 2010, the world's fastest Rubik's Cube solving robot, the Cubinator, was able to solve a scrambled Rubik's Cube in 18.2 seconds.
The robot will be on show at Swinburne's Open Day on 21 August.
