A Rubik’s cube was solved in just 0.103 seconds by a robot built by Purdue students

    1. I don’t understand these records. Like why does this matter since at these sub second records it’s literally a matter of “how many rotations to complete the algorithm” which would mean you could fake it by having a starting point with fewer rotations.

      Am I missing something?

    2. For anyone that can’t work one and thinks they would never be able to, there is a lady who is a school teacher that breaks it down with very easy to remember mnemonic devices (memory hacks like a nursery rhyme). It’s the one layer at a time version. You work out the first layer yourself, very easy, white cross, sunflower etc, then nursery rhymes for the second layer. Then the algorithms for the last layer. She makes it all very simple and teaches children to do it. You can absolutely do it. Don’t think for a second you cant. It will take 6-8 minutes to work once you figure it out. It may take you several hours or a day or 2 just keep going. Then you can learn the f2l version where you work the first 2 layers at the same time hence the abbreviation (f2l) and apply the algorithms for the last layer and it takes me about 2 minutes at my fastest time. You can do it. Its not an IQ thing. Its a patience thing. I only learned it because of a combination of 3 things…My friend gave me one and it was sitting on my kitchen table unsolved, I have severe adhd, and I didn’t want to wash a sink full of dirty dishes. If you avoid responsibility you can do it too. Trust me.

    3. How does this machine rotate each face and how do they get the axes frictionless enough to rotate this fast? That’s the true feat

      Sorry, but a robot solving a rubik’s cube is not as impressive as a human solving one. Computing is literally what computers do.

      The process of designing and building the robot is the interesting thing here, not that it solved a rubik’s cube.

    5. the first time i played the video i blinked and missed it, good thing there was a slow-mo version
