VIDEO: World record goes to fastest robot to solve a puzzle cube

The Guinness World Records have recognized Mitsubishi Electric for the fastest robot to solve a puzzle cube.

Equipped with high-speed factory automation (FA) equipment and control technology, the TOKUI fast accurate synchronized motion testing robot (TOKUFASTbot) managed the feat in 0.305 seconds (see video below), beating Mitsubishi’s own previous record of 0.38 seconds from earlier this year.

The robot can perform a 90-degree rotation in 0.009 seconds, thanks to a mechanism built with compact, high-power, signal-responsive servomotors and a colour-recognition algorithm developed with artificial intelligence (AI) technology. The servomotors, programmable controller, industrial personal computer (PC), touch panel display and cameras are all designed to achieve high-speed signal connection and inter-device control.

“Since establishing Mitsbushi Electric’s component production engineering centre in 2016, we have been developing and manufacturing high-tech motors, power semiconductors and related products,” says Yuji Yoshimura, the centre’s senior general manager (GM). “To demonstrate our technical capabilities in achieving high-speed, high-precision windings, which are key to increasing the productivity and efficiency of motors used in many of our products, our young engineers voluntarily worked to set the world record. This has motivated them to further develop their technical skills. We will continue to take on exciting challenges using the technology we have cultivated in motor development to support global manufacturing.”
