A robot built by engineers from Mitsubishi Electric has solved a Rubik’s Cube in just 0.305 seconds, setting a new Guinness World Record. To put things in perspective, it is approximately the same time a human needs to blink once.
Mitsubishi Electric has shared its record-breaking achievement on YouTube, with the video including slow-motion footage to allow viewers to properly see the robot’s solving process.
The previous Guinness World Record for solving a Rubik’s Cube in the least amount of time was held by a robot developed by MIT students. In 2018, this robot solved a Rubik’s Cube in 0.38 seconds.
In a chat with Guinness World Records, Tokui, engineer at Mitsubishi Electric and one of the leads on the project, said that he watched the video of MIT robot solving the puzzle and believed they have a motor that works better and faster.
Mitsubishi Electric’s robot, named TOKUFASTbot, encountered a jammed-up Rubik’s Cube in its first attempt to break the record. But the second attempt went better than expected, as TOKUFASTbot not only broke the record but also bested all of its previous practice times.
“Shaving off time as much as possible was difficult, but it was fun at the same time. I never had issues with motivation through the project,” Tokui told Guinness World Records.
