LEGO MultiCuber Solves Up To 5×5 Cubes
Writing by Evan Ackerman on Wednesday, 5 of May , 2010 at 12:13 am
If there’s one thing that robots are absolutely fantastic at, it’s solving Rubik’s Cubes. The task plays to their strengths: brute computing power coupled with fast and precise manipulation. A traditional cube is 3x3x3, but the MultiCuber is capable of solving cubes that are significantly more complex, up to 5x5x5.
The robot itself is built entirely out of LEGO including a Mindstorms NXT kit and Vision Command webcam. Both the solver application running on the laptop and the embedded software running on the NXT were written in C++. The laptop communicates with the NXT via USB.
The application uses a generic algorithm that can solve a cube of any dimension limited only by RAM and time. It has been tested with software models of cubes up to 100x100x100.
The physical robot can’t quite handle a 100x100x100 cube, of course… But, a version has been created that can solve 6x6x6 cubes, which have about 157 152 858 401 024 063 281 013 959 519 483 771 508 510 790 313 968 742 344 694 684 829 502 629 887 168 573 442 107 637 760 000 000 000 000 000 000 000 000 possible permutations. Next, they should start working on a robot to solve cubes with extra spatial dimensions, ’cause that would be pretty cool to watch.
Thanks David!

I must show some thanks to this writer just for rescuing me from this particular condition. Because of scouting throughout the online world and finding basics which were not helpful, I thought my entire life was over. Living without the presence of strategies to the issues you have fixed all through your good blog post is a critical case, and ones which could have in a wrong way damaged my entire career if I hadn’t noticed your blog. Your own personal natural talent and kindness in taking care of the whole lot was priceless. I am not sure what I would have done if I had not come upon such a stuff like this. It’s possible to at this point relish my future. Thanks a lot very much for your professional and results-oriented help. I won’t be reluctant to endorse the blog to anybody who needs counselling on this problem.
