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.
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 in this Rubik’s Build It Solve It Review, because we believe this is the one-way ticket to finally solving the cube!
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 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.
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
Okay, we’re going to be honest with you – you know how aggravating the traditional Rubik’s Cube is, correct? If you’ve ever tried to solve one, you probably know exactly what we’re talking about here. Yes, this kit offers a behind-the-scenes look and even comes with a 10-page instruction manual, but this doesn’t necessarily mean you will be solving the puzzle like a professional within seconds.
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. Rubix Build
