Guinness record: Mitsubishi robot solves Rubik's Cube in around 0.3 seconds
It can always be done a little faster: a robot has beaten the existing record for solving a Rubik's Cube by just under 0.8 seconds.

Mitsubishi Electric Corporation has set a new Guinness record for solving the Rubik's Cube puzzle (commonly known as the "Rubik's Cube") by an industrial robot. The robot, which is equipped with technology for high-speed and high-precision factory automation systems, solved the cube in just 0.305 seconds, beating the previous record set by a robot from the Massachusetts Institute of Technology (MIT) by 0.075 seconds.
The robot used is the TOKUI Fast Accurate Synchronized Motion Testing Robot (TOKUFASTBot). It is mainly used to improve electric motors, which are used in air conditioning systems or fans, for example. The robot has a three-axis rotation mechanism that is moved by compact, powerful, signal-controlled servomotors from Mitsubishi Electric.
High-speed components and AI
Mitsubishi uses high-speed cameras and the company's own artificial intelligence (AI) to detect the individual colored areas on the cube. Together, they deliver the necessary high and fast recognition performance. The servomotors are controlled via a high-speed signal connection. They can perform a 90-degree rotation in just 0.009 seconds. This is the only way to achieve such fast times for solving the Rubik's Cube.
The video, which was recorded on May 7, clearly shows how quickly the robot solves the Rubik's Cube. For comparison: the average blink of a human eye takes between 100 and 400 milliseconds. In this time, the TOKUFASTBot has almost solved the cube. So you have to look closely.
The magic cube, which consists of 3 × 3 × 3 movable blocks, originated in 1974. It was designed by Hungarian civil engineer and architect Ernő Rubik, who was granted a patent for the construction in 1976. The Rubik's Cube then spread throughout the world via Great Britain and the USA.

It was finally sold in Germany in 1980. The boom lasted for around two years. There was hardly a child or teenager in Germany who did not come into contact with the Rubik's Cube. After that, the hype died down.
While the initial focus was on being able to solve the Rubik's Cube in the first place, speedcubing events came into fashion later in the 2020s. The aim was to solve the Rubik's Cube in the shortest possible time. The current record for one person is 3.13 seconds. The record was set in 2023 by the US cube master Max Park.
