Watch This Machine Solve a Rubik's Cube Faster Than My Jaw Can Drop
About a year ago last march, a robot called the Sub1 solved a Rubikâs Cube in 0.637-seconds, earning it the Guinness World Record for being the fastest cube-solving bot. That honor now appears to be in jeopardy, however, as a pair of engineers have demonstrated a new robot that can solve a Rubikâs Cube in almost half that time: a mere 0.38 seconds.
According to the blog that Ben Katz and Jared Di Carlo created to show off their âRubikâs Contraptionâ, the bot relies on six Kollmorgen ServoDisc U9-series motorsâ"often used in high-precision, high-speed robot armsâ"to manipulate the puzzle cube at blinding speeds. To the naked eye, the movements are nothing but a momentary blur of colored plastic quickly coming into perfect order.
The Rubikâs Contraption also uses a pair of PlayStation Eye cameras to analyze and calculate an efficient soluti on to a mixed-up Rubikâs Cube before it ever makes a single move, which helps contribute to its speed. The creators say they have also developed special controllers for the robotâs six motors to ensure that only one is moving at any given time. If the movements of the motors happen to overlap, even for a hundredth of a second, it will simply tear a Rubikâs Cube apart, as demonstrated below.
Katz and Di Carloâs robot hasnât been reviewed by Guinness World Record officials yet, which is unfortunate, because the creators claim it could solve a Rubikâs Cube even faster than 0.38-seconds. Improving its efficiency, however, apparently requires time-consuming debugging, which the pair seem less interested in doing just to earn a fancy piece of paper and 15 additional minutes of internet fame.
