Determined inventor spends years painstakingly creating the world’s first self-solving Rubik’s cube
This determined inventor spent more than two years painstakingly building what’s believed to be the world’s first self-solving Rubik’s cube.
In the incredible footage, the classic toy can be seen being scrambled, only to suddenly start twisting and turning and eventually returning to its original design with nine solid-coloured sides.
It was designed and built by a designer from Tokyo, Japan, who, in bringing his creation to the world, said he only wished to go by “Human Controller.”
The idea for the project came to Human Controller in March of 2016, when he first witnessed a robot that had been programmed to solve a Rubik’s cube by itself.
At that point, however, no-one had created a Rubik’s cube that could be self-solving – and so the inventor got to work.
The following factors made the task extremely difficult, he said: the cube had to be the same size as the original, could be rotated by hand, could solve itself without simply rewinding, and required no wireless communication.
Human Controller completed the challenge on September 13, 2018 – some 29 months after he initially set out to solve the problem.
The previous year had had managed to create a Rubik’s cube that could slowly self-solve, but this required a stand, could not be held, and was much larger than the original.
According to Human Controller, the cube’s self-solving potential is infinite, as there is no limit to the number of twists and turns that can be made before the toy starts working to return to its original shape.
The toy was created using a 3D printing, servo motors and a small computer.
The 40-year-old added: “I was surprised to watch a robot that solves Rubik’s cubes on YouTube, in March 2016.
“But there was no self-solving Rubik’s cube yet, so I thought of trying it.
“It was the most difficult to pack gears and motors in the Rubik’s cube.
“A rotation sensor can recognize that it was turned by hand.
“So, it can also recognize that the arrangement of colors has changed.
“When it is placed on a table or held at a corner, it makes of a procedure to solve itself based on the colour arrangement.
“It then moves the motors according to that procedure.
“I don’t want to talk about because I might disappoint if the plan does not succeed.
“I intend to continue making works that will surprise people all over the world.”
