Feb 23 2010I'd Beat It (With A Hammer!): World's Fastest LEGO Mindstorm Rubik's Cube Solving Robot

Granted we've seen LEGO Mindstorm sets people have built to solve Rubik's Cubes in the past, but never anything that moves with the speed and dexterity as CubeStorm CubeStorm Cubestorm. Whoa, nice echo effect. Kidding, I'm hiding in the closet (my mom's trying to drag me to a doctor's appointment).

The Worlds Fastest Lego Mindstorms RCX Speedcubing Robot. Built entirely from lego elements with a lego web camera to scan the faces of the cube, The solve engine (algorithm) running on the computer is provided by the incredible "Cube Explorer "software which also provides the colour recognition required to determine the exact location of each coloured square. Thanks to Herbert Kociemba for making his work available to anyone wishing to use it! Respect! "Cube Explorer" has the ability to produce very fast solutions to a successfully scanned cube, usually around 20 face turns! Doesn't sound a lot , but it is believed that around 20 turns are enough to solve ANY 3x3x3 cube combination. I'm still working on "CubeStormer" I would like to see it reach sub-10 and feel it's close to that. but reliability begins to suffer when you start to push things just that bit too far.....

You know what else begins to suffer when you start to push robotics too far? Humanity. Just sayin', you ever seen that movie Terminator? I haven't. Jesus, I've got enough nightmare fodder.


Thanks to Osku, Logisticz, Gir, Ringo, Raúl, meeotch, Frank, james, Bolleke, PrestickNinja, raficus and Clint, who would have disassembled that sucker and built a sweet-ass LEGO castle.

I beat it too..... 'it' being my diiiiiiiiick

but can it beat me? Hopefully, look no hands!!

i want to put my testicles in that machine

@4 Ouch!

@2. Too much and you'll go blind, so they say.

@6 What? I can't see what you wrote..... just sayin

Seems like someone wasted their lifetime inventing such a pointless machine.

@8 Yes, they wasted thier life because after building it they instantly died.


@7. You need some help there?

I hate to post a *serious* comment, but I call shenanigans big time. Their "random" cube took far far less moves to solve than the average random cube, and it doesn't matter if a robot is solving it or not, there is still a minimum number of moves needed to solve the average scramble. Perhaps they did 100 scrambles and that was the one that happened to be close to already solved, but that is absolutely in no way representative of that robots average solving ability. His moves are slower than the average experienced solver, and out of thousands of solves my best time is in the 20 second range.

So let's hear a big resounding BUUUUUULL SHIIIIIIT for this robot.

This is awesome. Anyone who says it's a waste of time is juss jealous. Props to the creator(s ?). Though it does look creepily like the evil machine in the movie 9.

@12, Eric, you don't know what you're talking about.

Their 'random' cube may have taken far fewer moves than a PERSON to solve an average random cube, but there is an entire branch of computer science devoted to rubik's algorithms. I'm not joking.

Relevant bit: "Most mathematicians think it really only takes 20 moves to solve any Rubik's cube"

Number of moves shown in the full solve in the video: 20 (by my count, and counting the double-twist as two moves).

It's impressive that you can solve a rubik's in 20 seconds, but this is one of those things at which computers excel. It is EXPECTED that they will be faster than you.

Welcome to 2010.

waaaaah waaaaah robots are better than people

fuckin deal with it you pompous retards

No my son your nightmares are just irrational, and I will never let the robots take over.

A totally random cube! OMGWTFBBQSauce?

Dude its a simple algorithm. Not impressive at all.

@ 16

RAWR! (Raptor Jesus agrees..)

I really like the sound track. I just need a glow stick.

Now when we have 10-second disassembly and reassembly, it will beat this thing flat. Of course, it will need 600% more hands. For humans to keep up, we will, of course, need to reprogram fingers.

I believe CubeStormer is the ultimate example of human ingenuity and creativity in taking something a familiar as LEGO and using it to create an amazing speedcubing robot. There are other examples of similar creativity. For example have you seen the LEGO robot that can solve a 5x5x5 Rubik's cube? http://www.youtube.com/watch?v=t6DMaimg03E
