At the Swinburne University of Technology in Australia, a bunch of students just invented a machine called Ruby, which can solve a Rubik's Cube in 10.69 seconds—the fastest ever for a robot.

The robot scans each side of the cube using a webcam and applies a special software algorithm to figure out the solution. But the fastest time for solving the Rubik's Cube is still held by a flesh-and-blood human being, Feliks Zemdegs, who beat the cube in a blazing 6.24-seconds at the Kubaroo Open in 2011. [PhysOrg]
