Your goal is to have all four edges matching their centres. If you have this, then the cross is solved. If you have only two, then you could have one of two cases. Either the two matching edges are adjacent (next to each other) or opposite each other. If they are adjacent, hold the cube so that the two solved pieces are facing the front and left of the cube (shown in the left picture), then perform:
Using the LEGO Camera support, attach the camera.  The small black lens of the camera should fit between the two LEGO beam supports.  Secure the camera in place to the LEGO supports with some electrical tape.  This is a good time to make sure that the camera is position to be able to capture the entire Rubik’s cube.  You can take a test picture with the raspistill command
If you're still reading, congratulations on not being put off by the time requirements! The first thing you are going to need to know about solving the cube is how the turns you make can be represented by letters. Later on in this guide, you're going to need a few algorithms. These are combinations of moves that rotate pieces or just move them around to get them where you want them. These algorithms are written using this notation, so you can always come back to this section if you've forgotten by the time we need them. Rubiks Build It Solve It Instructions
The Rubik's Build It Solve It kid comes with all the parts necessary to build your own Rubik's Cube! Easy "how to" instructions, plastic cube pieces and tiles (including some spares), center core pieces, metal screws, springs, and screwdriver - all organized in a handy storage tray. Once you've built your cube, turn to the "You Can Do The Rubik's Cube" booklet and learn how to solve it.

The standard Rubik's cube has sides of about 2.2 in (5.7 cm) per square. Various other sizes have also been produced such as a 1.5 in (3.8 cm) mini cube, a 0.8 in (2 cm) key chain micro cube, and a 3.5 in (9 cm) giant cube. While the standard cube is a 3 × 3 × 3 segmentation other types have also been introduced. Some of the more interesting ones include the 2 × 2 × 2 cube, the 4 × 4 × 4 cube (called Rubik's Revenge) and the 5 × 5 × 5 cube. The shape has also been varied and puzzles in the form of a tetrahedral, a pyramid, and an octahedral are among types that were produced. The Rubik's cube also led to the development of game derivatives like the Rubik's cube puzzle and the Rub it cube eraser.
This Rubik’s Build It Solve It building kit is just for one player, and is one of the new toys for 2017. Winning Moves recommend that it will suit children of ages 8 and up. We have mentioned before, that this building kit is ideal for children and adults who like to figure things out. Anyone who likes to put puzzles together will love this. The Rubik’s Build It Solve It building kit will give you an inside look on how the cube works. You will also see how it is put together, and get some tips from the instruction manual on how you can solve it.
The manufacture of the first Rubik's cube prototypes was by hand. During the late 1970s, methods for mass production were developed and continue to be used today. Typically, production is a step by step process that involves injection molding of the pieces, fitting the pieces together, decorating the Rubik's cube, and putting the finished product in packaging.

The centre pieces on each face, as you may have noticed from playing around with the cube, can't be moved to another spot, only rotated. So we can use this to our advantage by building around the centres. The best centre to build your first cross around is the white centre, as many guides and resources on the web start with a white face, so if you need to look up some steps and examples elsewhere, your cube will look similar to the one that is being used in other demonstrations.
Begin with your cube solved. Once again, you want to start off with your Rubik’s cube in its solved position. Making a fish pattern on your Rubik’s cube is simple. The end result will have swapped two edge pieces so that the remaining ones look like a fish with fins. If you hold the cube diagonally it will look like a fish swimming away from you.[7]

Finally, we add a camera arm.  In the original design by MindCubr, this held the EV3 color sensor over the Rubik’s cube.  In our modified design, it holds a Raspberry Pi Camera over the Rubik’s cube.  We use two LEGO Mindstorms motors to manipulate the cube: the first sits below the cradle to rotate the cube, and the second moves the shuffler arm to spin the cube on an opposite axis.
For decorative purposes, a colorant is typically added to the plastic. The pieces of a Rubik's cube are typically black. During production, colored stickers are put on the outside of the cube to denote the color of a side. The plastics that are used during production are supplied to the manufacturer in a pellet form complete with the filler and colorants. These pellets can then be loaded into the molding machines directly.

The Rubik's cube (sometimes misspelled rubix cube) is a mechanical 3D puzzle, invented more than 30 years ago and still considered as the best-selling toy of all times! Yet, solving the Rubik's Cube is considered a nearly-impossible task, which requires an IQ of 160... Is that really so hard? Definitely not!! Just follow this simple step by step solving guide and you'll shortly find out that you can solve the Rubik's cube as well… Let's get to work! Rubix Build
