A recent video of the “Worlds Fastest Lego Robot” devouring randomized Rubik’s Cube puzzles, in a fraction of the time it would take most humans to complete the devilish contraptions, has captured the imaginations of large numbers of Japanese:
The robot is of course described as being built entirely from Lego elements:
Whether or not the Rubik’s Cubes are truly as randomized as suggested aside, it truly does appear to be an impressive work of robotics…

Eh, the timer is disappointing - not geek enough - everyone here knows how it should look like :) Someone should tell them :)
PS: 1) the SW for the brick recognition is totally simple - it's not a problem to recognize some colored rectangles and when you even know their positions
2) the solving SW isn't a problem either - if a standard human (not an autist) can solve it in a few seconds (using some known technique - that you can find on the Internet) then it's not such a problem for a robot/computer either.
I just ran a games convention (in Australia) where we had a Rubiks cube comp.
The human winner did it in about 8 seconds.
According to the organiser of the comp, there is (at most) about 24 moves to restore any randomised cube to "clean", once you see the pattern, you apply the correct formula and it is then just a matter of movement. I saw the winner playing with cubes afterward... he was solving a cube, one handed, without looking, in about 10 seconds.
The robot must have the patten recognising program installed, then it knows the set moves that it needs to make.
I am impressed, but would be more impressed if it was a robot that pulled off the stickers, and re stuck them the way all us normal people do to solve the dratted cubes.
you know it could just be a video played backwards of a robot scrambling a cube...
and the timer could have just been a countdown played backwards too
I can never trust online videos...
Doesn't really matter. The impressive part about the video is the robotics.
I could probably write a solving algorithm for a rubics cube myself, assuming someone else would do the optical recognition part of the software for me, given I have no experience on how to tackle the latter part. Can't be much harder than writing a Sudoku solver for the solving function itself.
Solving rubiks cubes algorithmically isn't very difficult. Building the robot is the hard part.
So it doesn't matter wether or not the robot -solves- the cubes, the fact that it can quickly scramble a cube like that is impressive enough by itself. Or are you suggesting the robot itself is faked, too? :p
I believe he input all possible patterns to this robot
how many is that?
Anyway, this robot ROCKS !!
I doubt that, considering there are 43,252,003,274,489,856,000 permutations. He probably programmed it the same way speed cubers go at it.
the robot is cheating, it got 4 robo-hands lol. Human got 2 D:
i have a friend that speed solves these freaking things. i guess the algorithm is fairly simple but it's still pretty impressive.
one more useless invention, people are strange... (c) but really it's completely useless =(
Yes, for some. it is seldom surprising that robotics - in this case, with the combination of Lego bricks - could solve a Rubik's cube.
For the hardware part, Lego bricks are made in such a way that they readily assemble without the need for glue or screws, probably with the exception of the movable parts.
The program shouldn't be so difficult for a person familiar with basic programming. The trick is to discover the mechanics and logic of solving a Rubik's cube.
The most impressive part would be a person actually DOING it and proving to humankind that it is possible, on top of other inventions of the inventor. For this, the inventor has my praise.
Crap, accidentally logged out. ↑ Mine. ^_^
A robot is the fastest at something? *gasp* What a surprise!
Read the title and took a glipms at the picture and the first thing I thougt
"What is this some Lego LHC?"
then I saw the RubixCube and was dissapoint.
Na, all the video is a shop
But can you sex it?
finnaly!!! the human race is safe now!!
get a life
Man I can just imagine the instructions for this :P
We're programming these lego mindstorm robots at school, we also had a project to present on the open day of our upper classes at school. Quite easy to program these, but for this you need more than one NXT.
its made from the mindstorm,maybe i can make one
Nice, but wake me up when they made an EVA :)
sorry, the gundam has the priority
but the EVAs can beat the Gundams... :)
A gundam prototype unit is already invented: http://www.youtube.com/watch?v=oVwbUljGs3g
:)
Cheating...Everyone who see it for the first time thinks it's a robot, so why not make a full robotic version (like Jet Alone) :)
Ｓｕｒｅ， ｂｕｔ ｔｅｌｌ ｍｅ ｗｈｅｎ ｙｏｕ ｇｅｔ ａｎ ａｎｇｅｌ ｔｏ ｍａｋｅ ａｎ ＥＶＡ ｏｕｔ ｏｆ．
Now we ghet: Which is the better mech? Gundams or EVAs.... Yup a flamebait....
Now remember that there is a real Gundam in Odaiba and no EVA whatsoever.....
God damn Skynet is making the first move. First rubik's cubes, then humanity... =(
Unimpressive.
Robots like this could have been made with the technology of the 90's as well. Sad to see it as something amazing in 2010.
What's amazing is that it's built using a Lego Mindstorm by some guy with time in his hands and knowledge in programming this thing!
"Love & support Michelle Dobson" How cute^^
I suddenly thought of what it would be like if this became a Transformer
Cool :) I can solve Rubik's Cube only in about one minute so far. I really should learn the Fridrich method.
Guess the software writer is pretty good at solving them as well by now ;)
Nah, you guys have been misinformed.
Solving the cube is way algorithmic and the methods are easily learned. Anyone who can solve a cube at all can do it under 2 minutes. Anyone can lower their time to about 50 seconds with a little practice.
Past that, it's knowing when to apply advanced algorithms (easy for a machine), cube awareness (being able to keep track which piece is where; a machine can easily remember, and can have multiple sets of "eyes"), and last but not least, dexterity, where the machine easily trumps the human.
In reality, solving a cube requires little or no thought (unless it's your first time and you have no guide).
Yeah, solving a Rubik's cube is just memorizing algorithms. Not as hard as it's been made out to be.
Nothing like math to solve rubik and build robots....
yeah, a program's only as smart as it's programmer
i'm kind of curious how he did it, looking at it just as it is, recursion would be the ideal way to go but thinking about the speed i can't help but be curious what he used if not that :3
It's a linear set of steps.
BUT CAN IT SOLVE 4x4x4 cubes??
A 3x3 cube at any given time can have (3x3x3)!/24 combinations. A 4x4 cube on the other hand has (4x4x4)!/24 configurations. The difference is 64x63...x28x27/24. And that's only combination per step, combinations in series would be much greater. Again, this is more conservative estimation using a brute force method. But it does show the level of complexity goes up by a lot when you increase the number of elements in a set.
I wish my lego robot could solve rubik's cubes like that. Mine just rearranges the stickers.
I suddenly thought of Terminator: the Sarah Connor Chronicles... o.O
And Judgment Day advances to the next stage... =D
Terminator made from lego ? now that interesting
They really are unstoppable, blow one apart and they'll just piece themselves back together.
Reminds me of the Large Hadron Collider.
honestly does it not remind you guys of that giant ring thing in the 1997 movie "Contact"?
I'd link a screenshot but for the life of me i can't find a decent picture of the thing. but i swear it looks close D:
So you're saying, while we're seeing the cube solved in 10 seconds, the machine actually took 18 hours??
Reminds me of the Large Hardon Collider.
I've got my LHC right here.
Where's your God now?
I wish I had a Lego...
Unlimited Lego Works XDDDDDDD
Give your son a set of playmobil and a set of Lego.
He takes the Lego:
Congratulations your son might bring it to something in his life
He takes the playmobil:
Is your son mental handicaped.
Not? I got some bad news for you.
He went to his sisters room playing teaparty with her dolls:
I got some bad news for you.
yay someone is using lego for the plural of lego.
I hate it when people say something like, "I made this out of legos!" then I question their intelligence.
I wish I had one million Lego.
TNinja..... That is pure genius....
Well if we ever hear of Fate/Stay:Lego....
I want a building instruction for this one.
I am the bone of my lego.
Plastic is my body, and cubes are my blood.
I have solved over a thousand cubes.
Unknown to death, nor known to life.
I have withstood pain to solve many puzzles.
Yet, these hands will never hold anything.
So as I pray.
Unlimited Lego Works.
Seriously, I haven't touched lego in years, and when I see them again, I find out that they have become a genius rubic solving machine.
The threat to humanity is not Skynet! It's Lego!
I wish I had a Leg....
Limited lego works...
and spray I do!

hehe, and I've got this one:
http://www.youtube.com/watch?v=lsY64ekW2HE
i wish i has a rubik's cube
And so I pray...
Unlimited lego works !
Ha, I built a coin sorting machine with mine.
Really? I always wished my LEGO robots would shoot lasers and rockets.You sir are modest.
Really? I always wished my LEGO robots would become human-sized, leave my room, and go off to work in the world of Real Estate.
Just buy Lego Rubik's Cube Robot from them. Can't be that expensive :/
