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!

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.
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.

If you were around in the 1980’s and did not live under a rock, you had a Rubik’s cube.  It was the 3D combination puzzle that had children and adults mesmerized trying to solve the impossible puzzle.  We would spend hours twisting and turning the cube to figure the solution. The cube was invented by an Hungarian professor of architecture, Erno Rubik, in 1974.  Although it took Erno over one month to solve his very own puzzle, it  became a fad and everyone had one. Consequently, it became the world’s best selling toy ever at that time. Rubiks Build It Solve It Instructions
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).

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”.

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.
Keeping white on top, turn the cube so that a different colour face is toward you. Follow the above instructions again. Repeat with the other two faces until the white cross is complete. This step is quite intuitive; you can do it for sure but it does take a little practice. Just move the white edges to their places not messing up the ones already fixed.  
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.
The robot will turn the cube to each face and the camera will take 6 pictures, one of each side of the Cube.  The Raspberry Pi will determine the cube configuration from the six pictures. The Cube configuration will be passed to the kociemba Python library to find an efficient solution. Finally, the robot will execute the moves to solve the Rubik’s Cube!
