Mitsubishi Develops Lightning-Fast Robot to Solve Rubik’s Cube
Mitsubishi Electric has made headlines with their latest innovation: a robot capable of solving a Rubik’s Cube-style puzzle in an astounding 0.305 seconds. Their TOKUFASTbot has set a new Guinness World Record, significantly beating the previous record of 0.38 seconds. It’s an impressive leap forward in both the robotics and automation fields.
The Evolution of Speed Cubing
Since the Rubik’s Cube was invented in 1974, it has enthralled enthusiasts and competitors alike, pushing them to solve it faster and more efficiently. The TOKUFASTbot epitomizes the culmination of these efforts. The robot uses a servo motor connected to each cube side capable of rotating 90 degrees in just 0.009 seconds, controlled by an AI color-identifying algorithm. A video demonstration showcases the cube being solved in 0.204 seconds, but the official Guinness record stands at 0.305 seconds due to stricter judging standards.

Achieving Precision and Speed
The achievement was met with widespread amazement online. Many were astonished not just by the robot, but also by the durability of the cube, which had to withstand incredibly rapid movements. The accomplishment sparked interesting comments and discussions:
- “They must have put a lot of oil on that cube.”
- “Anything faster than this will require ways of reducing friction in the cube.”
- “So, what can they do with this?”
- “Precise motor control is the backbone of manufacturing.”
Despite some obstacles—like a cube jam during the first attempt—the engineers were able to overcome these to secure the record. The official record, designated as “Fastest Robot to Solve a Puzzle Cube,” leaves some speculation if a branded Rubik’s Cube was in use.
Further Applications and Future Prospects
Mitsubishi also released short videos showing comparisons of their robot’s speed to everyday occurrences like a coffee spill or a soap bubble popping. These videos help illustrate just how fast 0.305 seconds really is, capturing the public's attention even further.
It’s clear that this technology has broader applications beyond just solving puzzles. The precise motor control and rapid processing speeds can be leveraged for automation in manufacturing, potentially reducing time-consuming processes and enhancing productivity.
