This is a rubiks cube solver that can solve any size cube, I have tested up to 17x17x17. The following tables show the reduction in move counts as the solver has evolved. The --normal table starts in July 2018, the earlier releases of the solver had drastically higher move counts, I think it was over 400 moves the first time I solved a 5x5x5.
Solving a 2x2x2 takes around 9 moves while solving a 3x3x3 takes around 20 moves but I am not working on those solvers so I did not include them in the tables below.

The kociemba solver is required to solve the larger cubes that have been reduced to 3x3x3.
$ git clone https://github.com/dwalton76/kociemba.git
$ cd ~/kociemba/kociemba/ckociemba/
$ make
$ sudo make install
$ sudo pip3 install pyhashxx
$ cd
$ git clone https://github.com/dwalton76/rubiks-cube-NxNxN-solver.git
$ cd rubiks-cube-NxNxN-solver
$ sudo make all
Run rubiks-cube-solver.py where --state is your cube state in kociemba order (URFDLB). You must run rubiks-cube-solver.py from the directory that holds your lookup-table*.txt files
Example:
$ cd ~/rubiks-cube-NxNxN-solver
$ ./usr/bin/rubiks-cube-solver.py --state LFBDUFLDBUBBFDFBLDLFRDFRRURFDFDLULUDLBLUUDRDUDUBBFFRBDFRRRRRRRLFBLLRDLDFBUBLFBLRLURUUBLBDUFUUFBD
One of my hobbies is building Lego Mindstorms robots that can solve rubiks cubes. I was able to find solvers for 2x2x2, 3x3x3, 4x4x4 and 5x5x5 but I couldn't find a solver for anything larger than that :( The solvers that I did find for 4x4x4 and 5x5x5 took quite a bit of RAM (several gigs) but I wanted to be able to run the solver on a Lego Mindstorms EV3 which is 300Mhz and 64M of RAM. So I decided to write my own solver and here we are :)
Here is the thread on speedsolving.com where I first posted looking for solvers. I ended up posting updates to this thread as my solver evolved: https://www.speedsolving.com/forum/threads/5x5x5-6x6x6-7x7x7-or-nxnxn-solvers.63592/
