Watch a robot solve a Rubik's cube in under .5 seconds

Robot solve rubik's cube within minute 832018

'We noticed that all of the fast Rubik's Cube solvers were using stepper motors, and thought that we could do better if we used better motors, ' Di Carlo wrote in a blog post.

The nameless robot is the creation of MIT robotics student Ben Katz and software developer Jared Di Carlo, though Katz describes it as a "contraption". The world was astounded when Sub1 managed to snag the world record for cube solving, but the Karz and Di Carlo's achievement with the Rubik's Contraption is unprecedented. According to the duo, the data provided by their tests suggest that the robot could complete the puzzle within 0.25 seconds.

The machine was made using six motors and motor drivers and Playstation Eye cameras - the cameras once used for gaming on the old Playstation 3 console. Additionally, the robot is designed in a way that ensures only one of the six motors is operating at any time. "For the time being, Jared and I have both lost interest in playing the tuning game", writes Katz. Therefore, the tightened cubes reportedly fared better during their tests and in their record-breaking attempt.

As Katz pointed out, several Rubik's cubes were destroyed in the process of their tests. Katz mentions that while a human player would loosen the cube up to make it easier to turn, a robot takes an opposite approach for solving the puzzle.

Katz was generous enough to share the components he and his partner used to create the robot that established speed record.

Katz gives a thorough rundown of what was involved in making the robot on his blog, just in case you want to try something like this for yourself.

A microchip, the "brain" of the machine, then uses a complex algorithm to lay out instructions on how to solve the cube in less than 0.15 milliseconds. Once slowed down to.03 times regular speed, the Rubik's Cube can be seen shattering. "The machine can definitely go faster", Katz said.

He beat the previous world record holder by just 0.05 seconds.
