The fastest humans can solve a Rubik’s Cube in about five seconds. To the average person, that statistic is pretty astounding. Unfortunately for anyone aspiring to be the next record holder, humanity’s best doesn’t hold a candle to the skills of a homemade robot.
Jay Flatland and Paul Rose have built the world’s fastest Rubik’s Cube-solving robot. The process takes all of 1.019 seconds from start to finish, leaving man’s best time in the dust. It’s a feat made possible by a few rather low-tech tricks.
First, four USB webcams quickly read the state of the cube, which is then uploaded into a PC application that runs on Linux. Then, the application is fed into a well-known algorithm which pinpoints the fewest number of moves to solve the cube in a speedy manner. The lightning-quick acceleration and deceleration of the robot is controlled by six stepper motors that are used to turn the cube. The result, a Rubik’s Cube that’s completely solved in 1.019 seconds.
The Rubik’s Cube-solving robot’s time is currently being submitted for the new Guinness World Record.
Watch the video above to see the robot solve the Rubik’s Cube several times, with only slightly varying results. And if you think that’s impressive, wait until robots graduate from college.[Gizmodo]
