- A MIT student and a software developer built the ‘Rubik’s Contraption’ which managed to solve the colorful 3D puzzle in an astonishing 0.38 seconds
- That time smashes the previous Guinness record
A student from Massachusetts Institute of Technology (MIT) and a software developer constructed a robot capable of solving a Rubik’s cube in a fraction of second.
Ben Katz, a masters student at MIT’s Biomimetic Robotics Lab shared the video of the machine completing the puzzle in 0.38 seconds.
Katz said the actual motion time is about 335 milliseconds, with each 90 degree move taking about 10 milliseconds.
“The machine can definitely go faster, but the tuning process is really time consuming since debugging needs to be done with the high speed camera, and mistakes often break the cube,” Katz said.
Meanwhile, software developer Jared Di Carlo said that one of the secrets for beating the previous best time was using better motors.
“Our solve time of 0.38 seconds includes acquiring the image from the webcam, detecting colors, finding a solution, and actually rotating the faces of the cube,” says Di Carlo in a blog post.
Guinness World Records currently lists a robot named Sub1 Reloaded as the record holder for solving a cube in 0.637 seconds in late 2016.
