Since the center pieces cannot be moved relatively to each other it's important to solve the edge pieces correctly in relation to each other. For example, when solving the white in our case- the green center piece is to the left of the red center piece, therefore the green-white edge piece should to be solved to the left of the red-white edge piece (see image).
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!

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 arrangement of the cube is an excellent method to improve the cognitive, visual, spatial and motor abilities in kids. The process of arranging the cube will enable children to exploit their spatial and visual skills as they learn to adjust the tiles. It also enables children to identify colors and allow them to create perfect combinations. Check it out here.
Now you need to orient these pieces. Refer to the next picture. As you can see, the orange piece matches the orange centre. Look at the edges on your puzzle. You could have none matching, two matching or all matching. If you have all four edges matching the centres, your cross is solved. If you have none matching, perform a U move, then look around the cube again. You want to have at least two matching. If none of them match, do another U move. Repeat until you have either two or four edges matching their centres.
Simply put the 1x1x3 is a pseudo puzzle, It fills a gap in the collection but its not exactly complicated to solve. The way this puzzle was made was by using two centres and a core of a QiYi Sail. As these parts already spin like a 1x1x3 should all I had to do was make these parts into cubies by adding some apoxie sculpt and sanding them smooth. This puzzle was made in an afternoon and stickered the following morning while I was also building my 'Mefferts bandage cube'.

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
