Ben Katz, an understudy at MIT, alongside software engineer Jared Di Carlo created a robot that can solve a Rubik’s cube by utilizing a different sort of engine on their “Rubik’s Contraption.” The robot was done with solving the Rubik’s cube in only 0.38 seconds.
Contrast that with the records held by people. Guinness World Records remembers US-inhabitant high schooler Patrick Ponce as the speediest Rubik’s cube solver. He accomplished the task in 4.69 seconds in the month of September a year ago.
Di Carlo, whose robot tackled a Rubik’s cube in 0.38 seconds, wrote in a blog entry: “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.”

The present record of solving a jumbled Rubik’s cube is held by German designer Albert Beer and his robot called Sub1 Reloaded. It tackled a disordered Rubik’s cube in a matter of 0.637 seconds. The feat was acknowledged by Guinness World Records in 2017.
With DiCarlo, the pair utilized Kollmorgen ServoDisc engines. “The motor is coreless, so there are no heavy steel laminations on the rotor, and there’s no steel to saturate, so it can accelerate insanely fast. In a 10-ms quarter-turn move, the motor reaches over 1,000 rpm,” he clarified in his blog entry.
