The record for solving a standard 3x3x3 Rubik's cube by a robot from Mitsubishi Electric is just 0.305 seconds, far surpassing the human record of 4.48 seconds, achieved by Yiheng Wang from China.
Mitsubishi Electric has released a video showing a robot solving a standard 3x3x3 Rubik's cube in 0.305 seconds, faster than the human eye can track.
The main person behind the record attempt is Tokui, an expert at Mitsubishi Electric's Components Manufacturing Technical Center, where he focuses on motor development. After watching videos of the previous record-holding robot, Tokui believes their motor is better and could break the speed record.
The TOKUI Fast Precision Synchronized Motion Testing Robot (TOKUFASTbot) from Mitsubishi Electric's Components Manufacturing Engineering Center can perform a 90-degree turn in 0.009 seconds thanks to its unique rotation mechanism, which is made from compact, high-power servo motors, and an algorithm developed using proprietary AI technology to recognize colors. The servo motors, programmable controller, industrial PC, touch screen, and camera are all designed to achieve high-speed signal connection and control of multiple devices.
In the first official attempt, the Rubik's cube got stuck again because it couldn't keep up with the robot's speed. So the team continued to work hard to keep it from getting stuck, and in the second attempt, the robot completed it in a time it had never achieved during training, setting a world record. TOKUFASTbot's time of 0.305 seconds far exceeded the human Rubik's cube solving record.
