The most important part in the manufacture of a Rubik's cube is designing the mold for the various pieces. A mold is a cavity carved into steel that has the inverse shape of the part that it will produce. When liquid plastic is put into the mold, it takes on the mold's shape when it cools. The creation of the mold is extremely precise. The cavity is highly polished to remove any flaws on the surface. Any flaw would be reproduced on each of the millions of pieces that the mold will produce. In the manufacture of the cube parts, a two piece mold is typically employed. During production, the two mold pieces are brought together to form the plastic part and then opened to release it. The tool includes ejector pins that release the molded parts from the tools as it opens. All the parts are molded with auto gating tools that automatically remove the parts from the sprue as it is ejected. The molds are also produced with a slight taper, called release angle, which aids in removal. Finally, when molds are designed, they are slightly bigger than the pieces that they ultimately will produce. This is because as the plastics cool, they shrink. Different plastics will have a different shrink rate, and each tool must be specifically designed for the material that will be used.

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.

Even in the book, during the first step, you’re told that you will need to practice and trial by error. Personally, we feel that this cube will be more fun for children and adults that enjoy puzzles and don’t mind the complications behind a Rubik’s Cube. You must have patience when it comes to building and practicing. However, once you are finally able to solve it, you’re going to be pretty proud of yourself and the people around you are going to be impressed because it really takes a lot to solve one of these cubes.
Maybe all it takes to solve a Rubik's Cube is to see how one is made, and that's what kids get to do with the Rubik's Build It, Solve It kit. It comes with all the pieces, tools, and instructions kids need to build their very own Rubik's Cube. Once built, there is a 10-page instruction booklet that guides kids through solving a Rubik's Cube. From identifying the parts of a Rubik's Cube to solving basic Rubik's puzzles, kids are given a slow introduction on how to use their Rubik's Cube and progress to harder and harder challenges.
The Rubik’s cube has recently begun making a comeback. Invented in 1974, it is the world’s best-selling toy. But solving them takes thought, effort, and skill . . . so why not let a robot do it? In this project, we take a Raspberry Pi, a BrickPi, and a set of LEGO Mindstorms and build a Rubik’s cube solving robot. Simply place an unsolved Rubik’s cube in the solver, run the python program, and your Rubik’s cube is solved!
Do you remember those complicated little Rubik’s block that we would sit there trying to figure out for what seems like hours? Did any of you guys/girls ever solve them? Maybe all it takes for us to solve the “cube” would be for us to see what it’s all about. While there are many mesmerizing toys that are about to emerge into our world, today, we would like to take a close look at the Rubik’s Build It, Solve It, because we believe this is the one-way ticket to finally solving the cube!

The individual pieces that make up the Rubik's cube are typically produced from plastic. Plastics are high molecular weight materials that can be produced through various chemical reactions called polymerization. Most of the plastics used in a Rubik's cube are thermoplastics. These compounds are rigid, durable, and can be permanently molded into various shapes. The plastics used in the Rubik's cube are acrylonitrile butadiene styrene (ABS) and nylon. Other plastics that might be used include polypropylene (PP), high impact polystyrene (HIPS), and high density polyethylene (HDPE).
An important thing to note is that this task is not a light one. It may require several hours of attempts. If you'd rather just solve the cube in your hand and forget about it rather than being able to solve any cube you're given, there are plenty of solvers available on the web. However, the satisfaction of holding a completed Rubik's Cube in your hand and thinking “I did that, and I can do it again” is greater than most, mainly due to the fact that the puzzle has been present in all our lives at some point. By the mid 1980's, an estimated fifth of the world's population had attempted to solve the cube. If you want to stand out and say that you can defeat the puzzle, time and determination is a large factor.
We add the BrickPi3 to the LEGO assembly.  We used the LEGO EV3 “wings” to support the BrickPi3 and make it level with the BricKuber body.  This is a good step to add 8XAA batteries to the power pack and attach the BrickPi3 power pack to the LEGO assembly.  For programming you can power the BrickPi3 via USB power to the Raspberry Pi, however to move the motors you will need to supply power with the Power Pack.        

If you have 2 adjacent well permuted corners- turn the upper face once clockwise (U). That move will reposition the corners into a situation which only one well permuted corner will remain while the other three corners needed to be rotated counter-clockwise. Now just execute the algorithm above, and by this single execution you actually completed this step (remember to execute this algorithm from the correct angle – when the well permuted corner is on the back right. see algorithm image above).

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.
When it comes to building the Rubik’s Cube, it’s not as hard as it looks. In all actuality, it will take about fifteen minutes and the instructions are easy to follow. When it comes to placing the colored tiles, make sure you pay attention to where you’re supposed to place them, because if you snap them in the wrong place, you won’t be able to remove them. Yes, you will still be able to use the Rubik’s Cube, but you won’t be able to follow along with the instruction guide on solving the puzzle.

Building the Rubik's Cube is pretty easy to do. It took us about 15 minutes, and the instructions were fairly easy to follow. Make sure you pay attention to where you are supposed to place the colored tiles because if you snap them on in the wrong place, you can't remove them. You'll still be able to use your Rubik's Cube, but you won't be able to follow along in the solution guide.
If it comes to constructing the Rubik’s Cube, it’s not as difficult as it seems. In reality, it is going to take approximately fifteen minutes and the directions are simple to follow. If it comes to putting the coloured tiles, be sure to look closely at where you’re supposed to put them since in the event that you snap them in the incorrect location, you won’t have the ability to eliminate them. Yes, you will continue to have the ability to use this Rubik’s Cube, however you won’t be able to follow along with the documentation manual on solving the mystery.

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.

Just because this kit gives you a behind-the-scenes look as to how a Rubik's Cube is made along with tips for how to solve it doesn't mean that you'll be solving it like a pro within seconds. Even the solution booklet itself says that the first step will take practice and trial by error. So this is definitely going to be more fun for kids or adults who enjoy the puzzlement of a Rubik's Cube and have the patience to build it and practice using the solving tips. But once you finally do solve it, you'll be pretty proud of yourself, and your friends and family will be impressed. Rubix Builders
