A robot can solve in half Second Rubik’s Cube ,The video put online details the operation of the robot. It consists of several pieces combined in 3d, four webcams, one engine for each side driven by an Arduino and it is connected to a computer on Linux.

That was a Rubik’s cube being solved in 0.38 seconds.  The time is from the moment the keypress is registered on the computer, to when the last face is flipped.  It includes image capture and computation time, as well as actually moving the cube.  The motion time is ~335 ms, and the remaining time image acquisition and computation.  For reference, the current world record is/was 0.637 seconds.


The machine can definitely go faster, but the tuning process is really time consuming since debugging needs to be done with the high speed camera, and mistakes often break the cube or blow up FETs.  Looking at the high-speed video, each 90 degree move takes ~10 ms, but the machine is actually only doing a move every ~15 ms.  For the time being, Jared and I have both lost interest in playing the tuning game, but we might come back to it eventually and shave off another 100 ms or so.  

At the moment, the new world record of Rubik’s Cube is being studied. The Old world record made by a robot is 3.253 seconds.


Waiting for a new world record

The two inventors are still awaiting the return of the Guinness record of whether their performance is homologated by the famous body or not because the Rubik’s cube has undergone certain modifications, a criterion which can be disqualifying .


Another video makes it possible to see the processes of the resolution in slow motion. It makes it possible to realize that these 0.38 seconds pass in a flash by drastically slowing down time.

A robot can solve in half Second Rubik’s Cube

According to Ben Katz who gave some details about his creation on his personal blog, the robot performs a rotation every 0.015 seconds. The device does not need the help of a human to find the solution.

Two Playstation Eye cameras are used to analyze the toy and a computer subsequently determines the movements to be made.

Katz also states that he and Jared Di Carlo could potentially reach 0.28 seconds by adjusting the machine, but that they lack interest in doing so at present. For this performance, even with a less camera, the robot can still get away without worries.

Pending the approval or not of the Guinness of records, it must be admitted that the exploit of these two young men is appreciable.
