Here, we're looking at the colours that aren't solved. There are 21 different cases for the top layer, but we only need a couple of algorithms to solve them all. The first thing we want to find is headlights. Only 2 of the cases don't have any headlights (one of them is if you skip this step, and the cube is already solved). For the one case without headlights, just perform the algorithm below from any angle. This is a better case because when you do the next step, the cube will be solved already. Rubix Builders
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.
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.
From these early riddles and word problems, toy puzzles were naturally developed. In 1857, the Irish mathematician Sir William Hamilton invented the Icosian puzzle. Sometime around 1870, the famous 15 Puzzle was introduced, reportedly by Sam Lloyd. This puzzle involved numerical tiles that had to be placed in order and became extremely popular in the early twentieth century. In 1883, French mathematician Edouard Lucas created the Tower of Hanoi puzzle. This puzzle was made up of three pegs and a number of discs with different sizes. The goal was to place the discs on the pegs in the correct order.
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.
If it comes to constructing the Rubik’s Cube, it’s not as difficult as it seems. In reality, it is going to take approximately fifteen minutes and the directions are simple to follow. If it comes to putting the coloured tiles, be sure to look closely at where you’re supposed to put them since in the event that you snap them in the incorrect location, you won’t have the ability to eliminate them. Yes, you will continue to have the ability to use this Rubik’s Cube, however you won’t be able to follow along with the documentation manual on solving the mystery.
Rubik’s Build It, Solve It is similar to the conventional Rubik’s block, but with a twist. This block includes each the tools, bits and directions kids need to be able to construct a Rubik’s Cube of the own. After this block was assembled together, there’s an education booklet (it’s’s 10-pages in duration) which will direct you through the procedure for solving the Rubik’s Cube (eventually). Here, you’ll find everything from identifying the areas of the block to solving fundamental puzzles. With this toy, kids will be provided a slow and continuous introduction about the best way best to use the block and progress to harder struggles. Rubix Build
