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.

Rubik’s Build It, Solve It. Can you recall those complex small Rubik’s cube which we’d sit there trying to work out for what seems like hours? Did any one of you guys/girls ever resolve them? Perhaps all it requires us to fix the “block” is for us to find out exactly what it’s about. When there are lots of mesmerizing toys which are just about to emerge into our planet, now, we’d love to have a good look at the Rubik’s Build It, Solve It, since we think this is the one time ticket to eventually solving the block!
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.  
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
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
