Robotic Rubik's Cube Solver for Thesis Proposal
Good day to each and everyone.
It took me quite a while to find this website. Just got lucky and bumped on this site.
My name is Robert, and I am now planning of creating my own version of a robot that is capable of solving a Rubik's cube for my thesis proposal. I have already studied some of the tips from the other websites, regarding the algorith in solving this puzzle. Applying all the tips that I have learned, I bought a Rubik's cube and tried solving it. I was never successful though.
Out of frustration, I tried to look for an interactive website similar to this one where I could be able ask for advices from real people who truly knows this puzzle.
If it would be possible, it would be better to make an appointment with anyone of you here, who is interested of personally teaching me the basics to the advance techniques.
Of course, every appointment, there is a "consultation fee", which I am willing to give, for as long as I will be taught the necessary information.
I am just hoping that you will not ask a lot.
Thanks and More Power.

Re: Robotic Rubik's Cube Solver for Thesis Proposal
A few years back, a UP student named Benjo Enriquez (who is also a member of this site) submitted a thesis concerning the intricacies of the Rubik's Cube and its mathematical nature. Also, today, a known internation cuber, Stefann Pochmann, is also writing his thesis that centers around a computer program that solves the cube.
If I am free, I can meet up with you to tell you the history of the cube and who else you can approach about this. The list, though, is nigh endless. If you are intent on doing this, you have to contact a lot of cubers around the world. A robot (RuBot and RuBot2) already exists for this purpose, but I doubt if the creator would be willing to share the information regarding his creation.
And, to be honest, the system being used by humans vary greatly from the system being applied by a computer program or robot. It's hard to explain it here, pero there are a lot of cubers here who can enlighten you about them.
Text me at 09154042497 if you have any more questions or check the cubemeet section so you can be updated.

Re: Robotic Rubik's Cube Solver for Thesis Proposal
Hello Robert!
I understand your predicament. Although I would very much would like to help you, I believe we cannot.
The robotic cube solvers you might have seen in Youtube or elsewhere do not use the same techniques normal people use. We, being bounded by the limits of our calculating capacity, resort to systematic methods of solving the cube, requiring us to constantly check on the cube right every move sets to know what to do next. The robots, on the other hand, have builtin programs that try to find the shortest solution possible in one calculation, and therefore could have even solved cubes blindfolded.
Although, if you do want to create a robot that has the same solving ability as a normal person would have, then I guess we can help you.
I'm interested though. Do you know how to develop the robot's eye that analyzes the current pattern of a cube?

Re: Robotic Rubik's Cube Solver for Thesis Proposal
Bryan is correct. That's the difficult part of creating the robot: the solution. The best human system is known as the CFOP and it involves a notsohigh number of algorithms (100+) to solve the cube in four general steps. However, unless your robot's eye can adjust at every turn, it would be almost impossible to apply CFOP to your robot.
Various programs like the ACube and the Cube Explorer have revolutionized cubing in such a way that they can find the shortest solution in a solve without brute forcing (while the shortest possible solution stands at 25 moves, ACube can only give up to around 40 moves because less moves need more computer power). These programs were modified by robotics enthusiasts to create their cubing robots. However, that is only as far as most of us here know. There has never been an official attempt in this country to create a RuBot imitation.
But Bryan's offer is good: if you want to have a robot that can solve a Rubik's Cube in the same way as humans do, we can help you a little bit. It will never be as efficient as the more complicated RuBots, though it can still solve the cube.

Re: Robotic Rubik's Cube Solver for Thesis Proposal
Sorry for doubleposting but I just want to grab everyone's attention with this specific post.
No one is to be paid for helping Sir Robert. We are a community of hobbyists that revolve around the concept of free dissemination of information. If you want to be paid, you should know perfectly what you are talking about and how you'll be able to help Sir Rober.
This stands as a reminder that we shouldn't abuse a standing offer. Sir Robert, there is no need to pay for asking for help. The most we ask from you is for this project to be realized fully.

Re: Robotic Rubik's Cube Solver for Thesis Proposal
I'm quite interested to the idea of the robot's eye capability of analyzing the given pattern of a cube. A specific sensor (colorsensitive) must be built in order for the robot to register the patterns and respond to it accurately based on builtin programs.
I have a no idea about any robots out there built for the same function, the idea of benjediman caught my attention about the robot's eye (or any part in that purpose).
I also thought of letting the robot unscramble a solved cube by itself with a programmed algorithms and solve the cube from that, wouldn't that be helpful? (though limited)...my two cents

Re: Robotic Rubik's Cube Solver for Thesis Proposal
Nice thoughts, dalton. However, the RuBot series may have already beaten us even to those feats. The RuBot even talks.
But hey, maybe we can think of other ideas that would be very unique for Mr. Robert's thesis.
What has been never done before is a robot with five actual fingers on two arms, and using them like a normal cuber would.
Anyways, I believe Mr. Robert has to contact the developers of ACube or Cube Explorer, if such is the case that he will be using either program.

Re: Robotic Rubik's Cube Solver for Thesis Proposal
Thanks everyone for the reply.
I really appreciate it.
Ngayon lang ako nakapaglogin ulit, sorry for the very late response.
Thanks.
To Benjediman and Jome:
I am actually trying to make a Robotic Cube Solver for my thesis proposal that deals with Artificial Neural Network applications. That is, with Artificial Intellegence, we can make programs/robots having a gift of seemingly "decisionmaking skills".
The robot would analyze the "current" color arrangement of the cube, and try to decide the best move, or series of moves to be performed.
I will be making a "thinking" robot, and not the sequential type of robots that you are implying.
The current pattern of the cube can easily be captured, instantaneously, with the help of a camera, and some image processing technology, with programming of course.
I believe, that this will gonna be the first step for my proposal.
I am pretty much confident that I can make this project successful, though with just some limited resources.
Currently, I am now trying to code the program that would control the problem solving algorithm of the system.
I have learned just recently some basic techniques in solving the cube, and used these techniques in making my tentative program.
I still have a lot of time actually, to be more accurate, more than a year to prepare the thesis proposal.
This project is for my thesis proposal in my MS ECE program.
And as I have said, this could be the beginning of it.
I am just significantly overwhelmed for the generosity and support coming from the Pinoy Speed Cubers Society.
Thanks talaga for the help.
Maybe I will just buzz all of you for some developments of my project.
Still have to confirm this idea to my professor if will it be valid.
For now,
Thank you very much and more power.

Re: Robotic Rubik's Cube Solver for Thesis Proposal
@robert papalid ece:
download CubeExplorer program, a cube solving program capable of solving the scrambled rubik's cube at an potentially optimal number of moves.
here is the link regarding the said program and the mathematics behind it
http://kociemba.org/cube.htm
i also suggest that you should read about a branch of mathematics called the "group theory" in order to understand the site's explanation on the program. here is one link that might help
http://www.ryanheise.com/cube/
in addition, i would like to say that the program was previously used to make a cube solving robot. The program is also capable of making a solution to the rubik's cube with the aid of a webcam (a potential eye for the robot). As benjdman and jome said before, this was used for Rubot 1 and 2.
in my opinion, cube explorer is better than ACUBE for some reasons:
1)more likely cube explorer is more bugfree since it had more revisions/debugging than acube (by the way, acube was derived from cube explorer, so more or less they have the same concept of algorithms)
2)the site of cube explorer program explains its algorithm neatly and elegantly. i think that the algorithm of this program is very well established since it is based on mathematical procedures.
3)well yeah, acube was pretty good too but the cube explorer is more userfriendly and has a webcam support.
i, too, am so overwhelmed by the fact that a filipino is really working on a cubesolving robot. i am happy that there is another interesting thread here in PCA forums. so i am glad to help you out coz i am also interested in programming.
to brief you with the algorithm used (i will try not to say mathematical terms since this is explained in the site given):
the algorithm is called TWOPHASEALGORITHM
definitionwise, the program actually does 2 subalgorithms:
algorithm 1:
the cube explorer solves the "current/scrambled" state of the cube and "unscrambles" it "incompletely." this algorithm solves the cube partially, leaving the cube into a "less complicated" state. then it counts the number of "moves" the algorithm 1 has. let that number be called "A."
algorithm 2:
the cube explorer gets the optimal number of moves (call this "B") to solve the cube from the "state" where algorithm 1 has left the cube and thus solving it "completely," i.e. all sides of the cube have only one color.
then the cube gets A+B=X. X should be the least number of cube solves. if not, the program does another "algorithm 1" and that said algo must be "at least A+1"(call this "C") number of moves then HOPEFULLY another "algorithm 2" with "less than B" number of moves(call this "D").
then the program hopefully gets a value Y less than X where Y=C+D. if not, the algorithm goes on and on until it finds an "potentially optimal" solution.
NOTE: when i said "potentially optimal," i hope, and i know you did (i wrote this part for the sake of other readers), you get that the solution given by the program might not be the "real optimal" solution.

another thing that might help: google up GOD'S ALGORITHM for solving the Rubik's Cube.
thanks for trusting PCA with your thesis proposal!!! i hope you enjoy our company!!!

Re: Robotic Rubik's Cube Solver for Thesis Proposal
Those information were really helpful.
I am now trying to read and study the links that you have given.
These approach of a problem solving technique, in this case, a Rubik's cube puzzle, is really amazing.
Thank you very much for the interest.
But maybe, I will try using a different approach or algorithm.
Because it would be very invalid if we will just to totally copy the concepts used by one technology or another; considering one of the criteria of a thesis proposal is novelty, right?
But I could use the said algorithms: TwoPhaseAlgorithm and God's Algorithm as my references, in case.
I have already downloaded the program. And maybe I will try to study it.
Thank you very much marc for sharing me these information.
Maybe, if I will be done with my tentative program, I could send a limited copy to the people here in Pinoy Speed Cubers, and ask for your professional feedbacks.
Thanks again for the overflowing support, interest, and generosity.
I was not really expecting this reaction or response from the people of the Pinoy Speed Cubers.
Maybe I could meet some of you, if given the chance.
I am from Cebu, and have been staying here in Manila to pursue my Masters. I have read on the main page of this website, that there will be an event called Cebu Open this April 19 to be held at USC?
And I will be home next week.
Could I attend? I mean, is it a free admission event?
I want to meet people like all of you to learn something new.
By the way, I have solved my first Rubik's cube last Sunday. And I tried to take note of my time after every succesful solving of the puzzle. My average was 7 to 10 minutes. Hope I could still improve.
Thanks again and more, more, more, more power.
God Bless.
