Mitsubishi’s bragging rights for designing the world’s fastest Rubik’s cube-solving robot have officially been stolen by a team of undergrads in Indiana. Meet Purdubik’s Cube: a machine capable of completing a randomly shuffled Rubik’s cube in just 0.103 seconds. Mitsubishi turned heads (and blocks) in May 2024, after its TOKUFASTbot solved a Rubik’s cube puzzle in just 0.305 seconds. Patrohay expressed hope ahead of Purdubik’s Cube Guinness World Record trial on April 21 that their machine could trim off a few more milliseconds to firmly set their record under a tenth of a second. It’s hard to imagine a robot solving a Rubik’s cube much faster than that, but then again, that’s what most people were saying this time last year.
