Mindstorm Rubik’s solver

It has been quite a while since we looked in on the world of automated Rubik’s cube solving. [David Gilday] built this one using LEGO Mindstorm parts. It uses a computer to calculate the solutions but unlike the standalone Tilted Twister, this creation can solve more than one type of cube. As long as the physical dimensions are between 5 and 6 centimeters on a side, the machine can solve 2, 3, 4, and 5 piece cubes. [David] wasn’t quite satisfied with that though. He built a separate machine to take care of the 6x6x6 cubes too. See both in action after the break.

    I just had a pie in the sky idea to try to build a rubik’s cube where the electronics to move the pieces are internally contained and it solves itself without visible connection to anything.

    The one thing dorkier (notice how I didn’t say nerdier) than playing with rubiks cubes – using lego blocks to solve them. This is a cool project and all but the people who play with rubiks cubes are almost universally douchebags.

    @kirov

    So does playing with lego even it out? Or is that double douchebag?

    good luck matt, dont know if you have pulled one apart but unless you make it huge the space constraints would make this difficult, but never the less would love to see it on HAD one day.

    also kirov well done on the hating/trolling as usual.

    Lego nullifies it a lot. Lego is in general pretty dorky but far less annoying. It is the type of people who walk around with rubiks cubes solving them in public, acting like memorizing algorithms is an accomplishment and deserves your attention that make most things involving rubiks cubes sketchy. Lego alleviates some of this as you are actually building and creating something rather than just being a hipster-geek trend whore, and the two cancel out a bit.

    Scariest moment of my life was when one of my friends solved a Rubik’s cube WHILE DRIVING!!

    He also knew how to solve a 7x7x7 cube, but that’s another story.

  7. Scott says:

    the “pie in the sky” idea to build a self solving cube could open a perfect excuse to play with some nitinol. By applying electricity you could manipulate the temperature of the material and get some movement out of it. Just a thought.

    This one’s pretty impressive too (runs really fast):

  9. mrgoogfan says:

    I think there are literally over four quadrillion possible combinations for a rubik’s cube.

    What’s the big deal I can solve a rubik’s cube in seconds, all I need is six cans of spray paint!

  11. Fili says:

    Well, the simplest self-solving cube would be one with 6 LCD’s on the sides, that simulate rotation by swapping colors :) I might build one, but I only have 5 identical LCD’s :(
    So 6 nokia screens, one microcontroller (maybe 6 resistive touch-screens to allow for user interaction) and you have a new toy :D

  12. Fred says:

    @Fili: something similar already exists, though the implementation details are a bit different. It’s called the Rubik’s Touchcube: http://www.rubikstouchcube.com/

    If you’re looking to buy one, shop around a bit for sales – prices vary from $50 (Best Buy on sale) to $200 (F.A.O. Schwarz).

    It takes some getting used to because an internal accelerometer only activates the top face to prevent spurious manipulations by the fingers holding the cube.

  13. my brother is one of those math geniuses/geeks that can do the cube in about 20 seconds. i have always been kinda jealous, lol.

    Hi, im teaching a class about Lego Mindstorm and i already taught them how to use all the censors. there are two more 3 hour classes and i want to do a competition and declare a class champion. what should i have them do? something like an obstacle course would be nice but i don’t know what to have in it. im open to other ideas though.
