LEGO Robot Breaks Rubik's Cube Solving Record

March 19, 2014


This is a video of LEGO robot CUBESTORMER 3 setting the world record for Rubik's Cube solving. It completes the cube in 3.253 seconds, two seconds faster than its father CUBESTORMER 2's previous record of 5.27 seconds. Of course there's also this robot that can solve any cube in under a second, but that one's a cheater because it has to have all the faces of the cube scanned first. Could you imagine building a LEGO robot that was actually capable of setting records? Because I can only imagine building one that explodes into all its pieces as soon as I turn it on.

Keep going for the record breaking performance.

Thanks to Gumby and E V I L A R E S, who have both built LEGO robots that solve MYSTERIES.

  • I'm not super fast, but I've solved several rubik's cube sizes and I know a bit about them.

    I feel like people stopped caring about speed solves because they are based on the starting position. It just happened to be in a position that could be solved in 3.253. That's not the solver, or the machine... that's a lucky start. Once you can solve in about 20 seconds or less, it's about how well oiled the cube is and how lucky you get on the starting position.

    agreed. i'm a lot more interested in proofs of shortest distance to solution.

    So they would have to make a robot solve a big number of random cubes and take the average time? That might make it a little fairer.

    pretty much this
