Alright, let us be clear here. Do you remember how aggravated you used to get when trying to do the traditional Rubik’s Cube. Did you ever try to solve it, remember how frustrating it could be. Well, let me tell you that the Rubik’s Build It Solve building kit offers you a behind-the-scenes look. Winning Moves even give you a 10-page instruction manual. But this does not mean you could be solving the puzzle within seconds like a professional.
Headlights are fairly simple to spot. Looking at the image, we can see on the right hand side that the orange edge has a green corner on either side of it. That is a set of headlights. The left hand side has two different colours on either side, so that is not a set of headlights. It is very important to note that a full bar (a blue edge has a blue corner on either side of it, so all three pieces are blue) is also seen as a set of headlights. This is only seen in one case of the 21 though, so you won't see it often. If you have a set of headlights on each side, ignore this part and read the section titled “The U Permutation”.

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
Here, we're looking at the colours that aren't solved. There are 21 different cases for the top layer, but we only need a couple of algorithms to solve them all. The first thing we want to find is headlights. Only 2 of the cases don't have any headlights (one of them is if you skip this step, and the cube is already solved). For the one case without headlights, just perform the algorithm below from any angle. This is a better case because when you do the next step, the cube will be solved already.
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.
Repeat the process. Turn back to your blue side and repeat the turns on opposite sides. Then, return once more to the red side and turn the opposite sides in opposite directions. And last, return once more to the blue side and turn the opposite sides in opposite directions. When you finish, you should have a staircase-like zig-zag across four sides of your Rubik’s cube.

The project uses the Pi to directly solve the Rubik’s cube. The BrickPi3 takes the unsolved Rubik’s cube and the Raspberry Pi takes a picture of each side of the Rubik’s cube with the Raspberry Pi Camera. The Pi creates a text map of the color squares that shows where they are located on the cube. When it has fully mapped the cube, the Pi uses the “kociemba” python library to map out the moves needed to solve the Rubik’s cube. This information is taken by the Pi and BrickPi3 to solve the Rubik’s cube using the LEGO motors. The result: a solved Rubik’s cube.
You can find assembly instructions for the BrickPi3 here. We will need to assemble the case, attach the BrickPi3, the Raspberry Pi, the Raspberry Pi Camera, add an SD Card, and add batteries. To make the software easier to setup, Raspbian for Robots comes with most of the software you will need already setup. You will need at least an 8 GB SD Card, and you will want to expand the disk to fit the full size of the SD Card. Rubix Builders
The Rubik's cube appears to be made up of 26 smaller cubes. In its solved state, it has six faces, each made up of nine small square faces of the same color. While it appears that all of the small faces can be moved, only the corners and edges can actually move. The center cubes are each fixed and only rotate in place. When the cube is taken apart it can be seen that the center cubes are each connected by axles to an inner core. The corners and edges are not fixed to anything. This allows them to move around the center cubes. The cube maintains its shape because the corners and edges hold each other in place and are retained by the center cubes. Each piece has an internal tab that is retained by the center cubes and trapped by the surrounding pieces. These tabs are shaped to fit along a curved track that is created by the backs of the other pieces. The central cubes are fixed with a spring and rivet and retain all the surrounding pieces. The spring exerts just the right pressure to hold all the pieces in place while giving enough flexibility for a smooth and forgiving function.
Simply put the 1x1x3 is a pseudo puzzle, It fills a gap in the collection but its not exactly complicated to solve. The way this puzzle was made was by using two centres and a core of a QiYi Sail. As these parts already spin like a 1x1x3 should all I had to do was make these parts into cubies by adding some apoxie sculpt and sanding them smooth. This puzzle was made in an afternoon and stickered the following morning while I was also building my 'Mefferts bandage cube'.

3 The Rubik's cube parts are taken to an assembly line. In this phase of production, the individual cube pieces are put together. Starting with the nylon core, each ABS center cube is riveted to the core with a spring spacer. The rivet is carefully controlled with a depth stop to ensure the spring is compressed just the right amount. Each center cube has a plastic cover that is glued on to hide the rivet. One of the six center cubes is left until the last part of the assembly. The ABS edges and corner pieces are individually stacked around the core. The cube is built from the bottom up and the last piece to be assembled is the final center cube which is again riveted into the core with a spring spacer and the final cap is glued on.
When you get round to building the Rubik’s Cube, you will find it is not as hard as it appears. The instructions are quite easy to follow and it will probably take you about fifteen minutes. When you get round to placing the colored tiles, pay attention to where they are supposed to go. Because once you snap them into place. you will not be able to remove them. Having said that. you can still use the Rubik’s Cube. What you will not be able to do is follow the instruction guide and solve the puzzle.
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
