Let's start with the white face. Try to form a plus sign on the top of the cube, matching the colors of the side stickers to the colors of the lateral centers. This step shouldn't be too hard, try to do this without reading the examples below.
Turn your cube upside down because we don't need to work with the white face anymore. We can insert an edge piece from the top-front position to the middle layer using a trick. Do the left or right algorithm depending on which side you have to insert the piece:
1. Hold the cube in your hand having an unsolved yellow corner in the highlighted top-right-front position.
2. Repeat the algorithm until this piece is solved.
3. Turn the top layer to bring another unsolved piece in the highlighted position.
4. Repeat R' D' R D until that one is also solved.
5. Do 3 and 4 for any other unsolved yellow corner.
Hi . I am trying to build a model of a fully functional rubik cube in Rhino. Can anyone guide me, if its possible, to any rhinoceros block library where I could find it. I could not find blueprints of it. Its for a test that I would like to make in the 3d print of the school.
This is the only texture map image I used for the cube, a plain black and white mask. I probably could have used transparency if I had given it more thought, but this worked Ok.

This Rubik's cube is a 2 and inch square. It is made up of multicolored moveable rows of squares. Each square is covered in red, white, yellow, green, blue, or orange vinyl. There are 9 squares on each side. Users try to make each side of the puzzle all one color.
The Rubik's Cube was a huge fad. Invented by a Hungarian named Rubik in 1974, the cube has been frustrating people for more than 35 years. It was put on the Western market in 1980 and became an instant hit. More than 350 million cubes have been sold worldwide.
Start by selecting the most suitable view for you with the little tabs above the cube. The default 3D view can be customized, setting transparent front faces or you can lift the hidden faces. Rotate the cube with the arrows or swiping the screen.
When the scrambled colors are properly configured and are matching your Rubik's Cube click the Solve command to get the solution. The cube solver will alert you if your configuration is not correct.
The invention, eventually renamed the Rubik's Cube, would become the most popular puzzle toy in the world, with more than 350 million sold as of 2018. The cube also inspired numerous artworks and films, and spawned a competitive sport called speedcubing that fills arenas with teenagers racing to complete the puzzle in the shortest amount of time.
I tried to rig Rubik's Cube by making each small cube separate and wireframe each small to its indicator, but when I rotate 1 indicator in step 1 and come to the next step (to rotate another section), the rig messes up and some cubes not moving with the rig, due the rotation of the 1st time.
Consider the Rubik cube as being composed of 26 cubes and a dummy object located at the center. For any move, 9 cubes are rotated about an orthogonal axis centered on the cube. Use a link constraint controller to link the 9 cubes affected by the rotation to the dummy for the duration of that rotation then rotate the dummy and then unlink them. Link the next 9 cubes to the dummy for each successive rotation.
Use a link constraint controller as shown here not simple object linking. This will let you establish linking for part of the animation then and the unlink the objects. For example, 9 of the small cubes will be linked to the dummy at the start of the first rotation while the other 17 cubes will be linked to the world. When that rotation is done the 9 will be linked to the world and 9 others will be linked to the dummy for the start of the next rotation.
To help navigate the twists and turns of the speed-cubing world, I read about cubes online and pored over cuber subreddits like r/Cubers and r/Rubiks_Cubes. In the course of my research, I learned that a few things differentiate the best cubes from the also-rans.
Taking these factors into consideration, I compiled a list of 14 3x3 cubes to test. (A 3x3 puzzle has three rows and three columns on each of its six faces. People who want a different challenge can try the 2x2, 4x4, and even larger cubes, but 3x3 cubes are the de facto standard.)
Rubik gave the world a wonderful brainteaser when he invented his cube. Its layers have plagued students and scientists alike, prompting studies of its mathematical and mechanical properties. (In pre-internet times, dozens of books were published purporting to teach anyone how to solve the rotating enigma.) But thanks to decades of innovation driven by competitors looking to eke out as much speed as possible, the newer cubes we recommend are simply easier and more pleasant to use.
Ernő Rubik, who invented the cube in 1974, has seen his color-matching puzzle go from a classroom teaching tool in Hungary to a worldwide phenomenon with over 450 million cubes sold and a mini-empire of related toys. (Nov. 30) (AP Video: Robert Bumsted)
My cube, when scrambled and placed on a desk, starts turning its faces to solve itself. It recognizes its color arrangement and solves from its current state, rather than reversing scrambled movements. It works independently without the need for an external computer or cameras, and can solve itself in about 30 seconds, no matter how scrambled.
Rubik's cube is a cube in which the 26 subcubes on the outside are internally hinged in such a way that rotation (by a quarter turn in either direction or a half turn) is possible in any plane of cubes. Each of the six sides is painted a distinct color, and the goal of the puzzle is to return the cube to a state in which each side has a single color after it has been randomized by repeated rotations. The puzzle was invented in the 1970s by the Hungarian Ernő Rubik and sold millions of copies worldwide over the next decade.
The group of operations on Rubik's Cube is known as Rubik's group, and the Cayley graph of that group is called Rubik's graph. The minimum number of turns required to solve the cube from an arbitrary starting position is equal to the graph diameter of Rubik's graph, and is sometimes known as God's number. While algorithms exist for solving a cube from an arbitrary initial position, they are not necessarily optimal (i.e., requiring a minimum number of turns) and computation of God's number is very difficult. It had been known since 1995 that a lower bound on the number of moves for the solution (in the worst case) was 20, it was not known until demonstrated by Rokicki et al. (2010) that no configuration requires more than 20 moves, thus establishing that God's number is 20.
The configurations of a Rubik's cube reachable using only half twists form a Nauru graph. Wolfram (2022) analyzed of the Rubik's cube via a multiway graph, the first few steps of which are illustrated above.
I'm a mechanical engineering student currently building a rubik's cube solver. I'd like to code a VSCode program (meant to interface with an arduino mega) that uses the basic CFOP method (solves cross -> corners -> second layer edges -> OLL -> PLL).
The simplest way of going about it would be to pretty much hardcode in a sequence of moves for each piece of the cube. For the first 4 edges and corners, this would be an absolutely ridiculous amount of code. Take the white-orange-blue corner; there are 8 possible positions in 3 different orientations, leading to 24 completely unique sequences of moves I'd have to account for. All in all, I predict it would end up being a 3000+ line program.
"take a piece and mess around with" will not work with the Rubik's cube problem - when you "mess around" with arbitrary moves, you destroy the order of the pieces you already placed correctly beforehand. Building a full search tree won't work either, that tree would require 43,252,003,274,489,856,000 nodes due to exponential growth.
It may be also a good idea to start with a simpler comparable problem first, for example the "15 puzzle", and collect some experience with it, before trying to solve harder problems like Rubik's cube.
