Mitsubishi Electric has been awarded the Guinness World Record for the fastest robot to solve a puzzle cube.

We often hear the expression ‘in the blink of an eye’ to describe something very quick. But how quick? According to Harvard University's bionumbers database, a blink takes 0.1 to 0.4 seconds.

The Japanese company’s TOKUI Fast Accurate Synchronised Motion Testing Robot (TOKUFASTbot) has solved a Rubik’s Cube in 0.305 seconds, in quite literally less than a blink of an eye.

The robot recently received the Guinness World Record for this achievement, beating the previous record time of 0.38 seconds, which was set by a Massachusetts Institute of Technology robot in 2018.

By comparison, the human record for solving a Rubik’s Cube is 3.13 seconds, set in June 2023 by Max Park, a 21-year-old US ‘speedsolver’.

Guinness World Records doesn’t officially call it a Rubik’s Cube, due to a historic trademark that was recently overturned – rather, it’s referred to as a 3x3x3 ‘puzzle cube’.
