JP Brown's Serious LEGO - CubeSolver
Lego Mindstorms RCX robot solves the Rubik's Cube.
: CubeSolver : PREAMBLE This robot solves the 3x3x3
In Jan 2001 fellow Mindstorms forums user 'agiecco' announced his intention to work on a robotic solution and, simultaneously, I saw that Rubik's Cubes were on sale at www.target.com
So I bought a couple of cubes and started getting down to business..
MECHANICS To achieve a cube solution, you must be able to rotate the whole cube by 90° in two orthogonal axes, and be able to turn a face by 90° relative to the rest of the cube
I opted to use the left and right grabbers to turn the faces; the yellow grabber can rotate the left face by an 90°; the green grabber can rotate the right face by 90°; or they can both turn simultaneously while the bottom grab is open to rotate the whole cube through 90°
The bottom gabber holds the center 'slice' of the cube when the left or right grabber is turning a single face, and also provides a 90° turn for rotating the whole cube
The tricky part is to re-orient the cube between moves to present the next face to be turned by the left or right grabber
The cube faces are generally too stiff for LEGO elements to turn This problem was solved by a tip I found on Lars Petrus's : lubricate the cube with silicone spray lubricant

Program to Solve Your Rubik's Cube
A computer program to help solve your cube.
Cube 1.42 Last update: November 18, 2005 This cube program enables the user to solve his Rubik's Cube
After entering the cube, the user can play with the cube or have the computer provide a solution
This means that the number of steps required to solve to cube will usually be a lot more than the optimal solution
However, the user can learn how to solve his cube himself by looking carefully at what the computer does
The computer will: * Solve the top of the cube -first the edges starting at the right/top edge and going in counterclockwise direction -then the corners starting at the right/top/front corner and going in ccw direction * Turn the cube around * Solve the middle layer of the cube * Make a cross on the top of the cube (edges are flipped ok, position may vary) * Solve the corners of the cube * Fix the position of the edges on the top Since the cube can be rotated using your mouse, I have chosen a naming convention that uses the colors of the side (=middle square) instead of the front/back/right/left/bottom/top convention seen elsewhere

Solving the Rubik's Cube Systematically
A systematic method for solving the cube.
Solving the Rubik's Cube Systematically Introduction You probably have seen many ways to solve the cube
But how much time and effort are required to remember these 'optimal' sequence of steps? How much time is required to practise with them so that you don't forget one of those long meaningless sequences of steps? If you stop playing with the cube for some time, would you still remember how to solve it using these optimal methods? This is a real life story
I haven't touched the cube for more than ten years
I have forgotten each and every sequence of moves I used to restore the cube
One evening my baby cousin scrambled the cube and noticed that she is incapable of restoring it
If it were you, could you have unscrambled the cube quickly? The method I described here is good not because it is fast
Better still, buy them one! The Strategy of 8 Corners These pages describe basic rules in designing algorithms to solve the Rubik's Cube
You would develop a new perspective of the cube, with which you can design algorithms and strategies on your own
Some prior experience on meddling with the cube and on using algorithms are needed
3x3x3 Puzzle Solution
A one-page solution that uses three simple arrow diagrams to indicate which plane
of the cube is to be turned a ¼ turn. No knowledge of notation required.
The three arrow diagrams used in the solution are: Arrow Diagram #1: Arrow Diagram #2: Arrow Diagram #3: The arrows indicate which plane of the cube is to be turned a ¼ turn
" B " with an arrow around it = turn the back plane of the cube a ¼ turn
I have spent days (hahahaha) trying to work out how to move the final pieces into position and became very confused as everybody has a different way of solving the cube
You have made it "easy" and now I can "finally" impress all my family (who CANNOT solve a "simple" rubik's cube)

... RUBIK's CUBE-LIKE PUZZLES The purpose of this page is not so much to explain how to solve the Rubik's cube but to try to explain how one can use mathematics to model the Rubik's cube, and related puzzles
The first few definitions below try to put the Rubik's cube on a firmer mathematical foundation by defining a permutation puzzle, such as the Rubik's cube, in the context of combinatorial game theory
Some links to web pages on related puzzles and topics are given below, followed by a short explanation of my (a commercial computer algebra and graphics program) code for the 3x3 and 4x4 Rubik's cube

Group Games
Animations that develop the theory behind such puzzles as the Rubik cube.
Group games Dipartimento di Scienze Matematiche Università degli studi di Trieste Java applets by: Probably everybody had in his/her hands the puzzle called 'Rubik's cube' or 'Magic cube'
It is made by a plastic cube whose faces can move in such a way that the small colored cubes which compose each face can permute
The aim of the game is to reconstruct the original cube
One can prove that the number of different configurations of a Rubik's cube is: 2 27 3 14 5 3 7 2 11=43252003274489856000, that is, about 0.4*10 20
In order to have an idea of how big is this number, suppose we want to show all the different configurations of the cube devoting precisely one second to each of them; this operation would take about 1370 billions of years (consider that the Sun will continue to burn for about 5 billions of years...)
Hence to show all the possible configurations of a Rubik's cube seems to be an impossible task, but this should not discourage us: to find a solution to the puzzle it is not necessary to know all the possible configurations, it is enough to manage some of them with sufficient ability

DIRECTIONS FOR SOLVING THE RUBIK'S CUBE These instructions can be used to solve a 3x3x3 and also a 2x2x2 starting from any combination of colors on a mixed up cube
Furthermore, the approach to solving the cube I take seems to be different than on the web
I have recently learned that the solution I describe was popularized by Minh Thai, the National Champion cube solver whose record Time in late 1981 was 26.04 seconds (he was on the TV show 'That's Incredible')
He went on to publish a booklet entitled 'The Winning Solution' (1982), talking about his method for solving the cube, a 'corners first' approach, based on the solution presented by Ideal Toy Company (The Ideal Solution, 1980), the book which I believe I learned this solution from
Marshall's, comparing various solutions.) Note: I also have for how to solve a cube when it has pictures on each face

HOW TO SOLVE A RUBIKS CUBE ?
Adam's Rubiks Cube Solution
A corners-first method, optimized for visual speed.
Adam's Rubiks Cube Solution Yet another description of how to solve the cube
My solution was strongly influenced by conversations with Jeff Varasano, back in the early 80's when the cube was still popular..
This solution is optimized for visual speed , because the slowest part of solving the cube is not making the moves, but locating the pieces to place
Hence it is very color oriented, using easy-to-spot patterns instead of more difficult questions most solutions normally require, such as "where is the correct position for this corner relative to its center pieces?" With a good cube, I was averaging (in 1981) 26 seconds over 100 attempts
Today, with a bad cube and out of practice, I would probably average around 45 or 50 seconds
During this solution, I've included instructions for both the expert cubist (fastest possible solution, but requires lots of memorizing), or for the beginner (memorize only four easy patterns to solve the whole cube, but takes much longer)
The pictures represent the cube as if you were looking at it straight on, at eye level
In all cases, the pictures below represent turning just one slice of the cube

If you solve it with or without reading the solution, send us your log file and we'll list you in the MagicCube4D hall of fame too! The mathematically inclined may be interested to know that the number of possible states for the 4D cube is exactly (24!x32!)/2 x 16!/2 x 2^23 x (3!)^31 x 3 x(4!/2)^15 x 4 which can also be expressed as 32! 24! 16! 2^22 6^32 12^15 or in decimal as 1 756 772 880 709 135 843 168 526 079 081 025 059 614 484 630 149 557 651 477 156 021 733 236 798 970 168 550 600 274 887 650 082 354 207 129 600 000 000 000 000 For comparison, the normal 3D Rubik's Cube has only 432 520 032 274 489 856 000 unique positions which is still huge
On the other hand, the 4D cube has more potential positions than the total number of atoms in the universe! Far more
Surprisingly, even though the number of 4D cube positions is frightenly large this doesn't mean this puzzle is that many times harder to solve
If you can already solve the 3D cube, then you're more than half way to solving this one

I first learned to solve the cube when I was nine years old
When I was ten, I entered a Rubik's Cube contest and placed in the top ten for the 17 and younger group
Back in the cubing days, I could solve the cube in less than 30 seconds
Most of my solution method comes from Jeff Varasano's book Jeff Conquers the Cube in 45 seconds
I have seen other solutions where you solve the cube in slices, but it seems more complicated and there are too many 'shortcut' moves to know
Introduction to the Cube The Rubik's Cube is a six color cube made up of 9 squares of each color on each face
According to the, there are 43, 252, 003, 274, 489, 000 different possible configuations, but only one of these configurations presents the 'solved' Cube
There are a couple of different color arrangements for the cube
But I also have a cube at home which has Blue and White opposites and Yellow and Green opposites
The Rubik's Cube is moved by rotating each face (slice) around it's center piece, thus mixing up the 4 faces on the edges of the rotated slice
The slices can be labeled and named: When most people start thinking about the cube, they see nine squares of each color that can be put in any random place on the cube

A cube has 43, 252, 003, 274, 489, 856, 000 (over 4 X 10^19) different positions
If you take a cube apart, there are 12 different ways that you can put it together such no set of moves will take the cube from one of the 12 assemblies to the other
When I was in practice, I could solve a scrambled cube in about a minute using about 65 moves (counting slices as a single move)
A Rubik's Revenge Cube from 1982
A Rubik's Revenge Cube has 7, 401, 196, 841, 564, 901, 869, 874, 093, 974, 498, 574, 336, 000, 000, 000 (over 7 X 10^45) different positions
When I was in practice, it took about twice as long and about twice as many moves to solve as the original cube
For an idea of the size of the number of possible positions on a Rubik's Revenge cube, note that a Rubik's Revenge cube is 2.6 inches (6.5 cm) per side and the earth's orbit around the sun has an average radius of 93 million miles (150 million Km) or about 2.3 X 10^12 cubes
