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.

4 Next, the Rubik's cube faces need to be labeled. The labels are made from sheet polypropylene material that is printed with the colors. The printed sheet PP is then laminated with a clear PP protective covering. The material is then die cut with the labels wound onto rolls. The labels are made with all nine squares of each face exactly aligned. This way the labels can be perfectly aligned when they are applied to the cube.
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.

Constructing the Cube is a superb way to exercise those fine motor skills, visual and spatial comprehension and cognitive thinking from children. When the block is placed together, it is going to challenge the small ones to use their spatial and visual understanding as they know to spin the tiles. The block also helps kids learn about colours and fitting them. Rubix Building Products
Dreamt up by cuber Daniel Stabile who posted a demonstration to YouTube and a how-to to Instructables, the paper cube is fully-functional if not particularly easy to use. On top of that, assembly will likely take you a while, but it will also teach about how the insides of these cubes—speedy and slow alike—actually function mechanically. In a video showing off the creations, Stabile demonstrates his first attempt, as well as a better-looking second version:

If there are no more edges left on the top layer, then they are probably either inserted in the right place but flipped, or inserted in the wrong place. To get an edge out of somewhere it shouldn't be, just insert one of the yellow edges into that slot. This should get the edge out and on the top layer, ready for you to use the above instructions to insert correctly. Rubix Build
