The world of Rubik’s Cube puzzles has long been a major brain challenge for those who like a brain teaser. However, it’s long been one of the most difficult puzzles, and people often find it nigh-impossible to get it right in a good period of time. Instead, they often take a good number of minutes to tie it all up and get the perfect pattern.
However, you might be pleased to know that Ben Katz and Jared Di Carlo, two software hackers, have got it fine-tuned. Indeed, they built a little robot with the purpose of quickly solving the Rubik’s Cube puzzle. The got the robot to a ridiculous record of just 0.38 seconds – far ahead of the 0.637 record that had existed beforehand.
Speaking about it on their blog, Di Carlo said that: “We noticed that all the fast Rubik’s Cube solvers were using stepping motors and thought that we could do better if we used better motors.”
This new and improved motor allows for 10 milliseconds to be all it takes to complete a single turn. With 19-23 turns being the average to solve a Rubik’s Cube, it would be finished it in just 0.25 milliseconds. At present, though, this only turns every 15 milliseconds!
“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 [Field-Effect Transistor].” Explained Katz.
The project, though, may yet continue: the boys plan to shave another 100ms off the full time it takes to finish the full job. At the moment, though, they have created a piece of history that has single-handedly helped to make Rubik’s Cubes look pretty simple, in comparison to the mental maze that they are in the eyes of most people!
