If you’ve at any time tried to 3D print a toy for one of your kids, you can have seen how limited the shelf life of toys in fact is – unless it’s awe-inspiring, many toys are only played with a few times. That says a lot of the staying power of the Rubik’s Cube puzzle, which is additional than forty years old may already. It yet captivates both children and adults, and which fascination has may already crossed over into the 3D printing community as well. Do you remember this record-breaking 3D printed Rubik’s Cube? The regular cube, howat any time, in addition yet interests folks – who are especially looking for ways to maximize solving speed. Well, the answer can be discovered in 3D printing, as two YouTubers have only uploaded a clip in which they use a 3D printed solving machine to set a new world record of less than 2 seconds.
For those of you who have mysteriously avoided the Rubik’s Cube all their lives, it was devised way back in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, it rapidly became quite talked about as a mathematician’s gimmick: only endlessly turning corners accomplishes nothing, but establishing a series of patterns can rapidly solve it. A classic cube, as you can understand, has six faces every with nine separate tiles. With the assist of stickers, they are divided into six solid colors: white, red, blue, orange, green, and yellow. The goal, of course, is to get all colors on a single side.

Some awe-inspiring records in completing these cubes have been set may already, but none have been so astonishing as what this machine by Jay Flatland and Paul Rose can do. They not long ago uploaded the clip at a lower place, in which they show off their machine capable of completing a cube in less than two seconds – a new world record. This is much swifter than existing records, which is 3.253 seconds for a machine and a quite astounding 4.904 for a human (held by Lucas Etter). In contrast, Jay and Paul’s machine is shown to achieve the cube four separate times, in 1.196 seconds, 1.152 seconds, 1.047 seconds, and 1.019 seconds, respectively. So not only incredibly swift, but consistently so.

So how does this awe-inspiring machine work? Well, the robot showcases four stepper motors which hook onto the cube, all encased in a custom 3D printed enclosure. Four webcams are installed, all hooked up to the PC to continuously scan the configuration of the tiles. That information is fed into the Kociemba Rubik’s Cube solving algorithm (running in Linux), which directs the robot to manufacture the necessary movements. This does need all four cameras to work to ensure which the algorithm has all the information it needs.

To get it to begin, a camera is initially covered with a piece of paper to block the algorithm – giving the user the time to manually scramble the cube. Once plugged in again and the paper is removed, the program collects data as rapidly as possible and feeds commands back to the stepper motors. It is an awe-inspiringly efficient 3D printed machine and unquestionably deserves its record. There’s only one tiny snag, as the duo has applied for a world record, but this hasn’t been approved only yet. Surely which’s only a matter of time?
