MindCuber - build your own LEGO Rubik's Cube solver

[IAssemble]

Would the 8527 set have the right parts for this model?

The earlier NXT kit you mention only has a monochrome light sensor rather than a color sensor. I also believe has different gears and other parts so it will need a re-design and either a color sensor bought separately or modified software.

I may consider re-designing MindCuber for the earlier NXT kit myself if there is enough interest (unless someone else does it first )

Thank you for your sharing,I completed MindCuber following your instructions and downloaded the MindCuber.rxe to NXT yesterday,but It worked abnormally,the cuber can not be turned,the turntable and arm is too biger than the cube,I measured my cube is 5.7cm*5.7cm,but the turntable is 6.3cm*6.3cm,what is your cube size?I'm your CubeStormer's fans from China,my English is limited,ask for your help,expect for your reply!

Thanks for deciding to try out MindCuber It is designed to work with standard 5.7cm cubes even though the turntable is bigger than this. Software turns the turntable a little more than 90 degrees and back each time to compensate for the difference. The main requirement physically is that your cube must be smooth and easy to turn. If it is too stiff MindCuber may not be able to complete each turn properly.

Please would you have a look at a few of the "Problem" videos that people have posted on YouTube - look at the "MindCuber" playlist on my YouTube channel to see if any of them help. If not, please let me know and I will try to help. The easiest way to do this will probably be for you to post a video on YouTube showing the failure so I can see it and try to work out what might be going wrong.

I hope this helps.

Thank you for your reply,I'm sorry to tell you about the "Problem" videos,in our country,youtube is forbidden to log in,so I can not get your help in that way,I may describ my problem incorrectly before because of my bad English level,my problem is MindCuber's arm can not turn-over the cube,It is not the turntable's turn-problem,I guess my cube is too small,I measured the turntable and the arm's "hand",so I asked you the size of your cube,I'll take a video and post it to www.youku.com tomorrow,It is the video sharing website in our country like youtube,I'll give you the link later,Thank you for helping me again!

so it does some form of f2l then a single ll algorithm? wow if a speedcuber could do that the wr would be like 3 seconds

You can read my mind. lol I was going to ask the EXACT SAME thing

wow if a speedcuber could do that the wr would be like 3 seconds

I don't agrea with that. feliks uses some zbll algs (1lll) and the WR is 5.66 so.....

i had trouble with that one and im trying this one just finished mine about to program it

me to.

Thanks for letting me know. I look forward to seeing your video on youku. I'll try and see if I can work out what is wrong when I see it.

No - LEGO changed the link slightly today I'll update the links everywhere I can find but I think it is now here.

I described the algorithm in summary here

 

[Damien Porter]

Wow, that looks awesome.

Can't wait to try it out

Thanks

Thanks for uploading this video. It is difficult to see from this angle but I think that the L shaped pieces in the middle of the tilt arm are connected the wrong way round so the beam across the tilt arm is too close to the cube.

Please look at page 98 of the instructions and check the L-shaped beams are connected correctly.

I hope this helps. Please let me know

I recently saw the video of the Void cube solve I just tried it. It scanned the cube 3 times before giving up. Is there a program change so it can solve the void cube or just the currant one to solve the 3x3?

Edit:

MindCuber needs different software to solve the Void Cube. It is not supported by the existing executable program and I am not planning to release a new executable program either.

Instead, I am hoping that when I release the source code that some people will try modifying it for themselves as a challenge!

Ok thanks.

I have built mine and almost have it working, but it has trouble scanning white cubes so I need a black one.

On a side note when you release the code, I am thinking of making a racing version. Use the touch sensors as a stackmat and have human vs robot.

Thank you for your help!Now,It works well,but sometimes it may scan error(I always caliberate it),expect the source code!Thanks again!

Does it have trouble with white cubes even when you calibrate? I have one white cube here that works reasonable well although it often has to scan twice.

I love your idea of adding touch sensors for a stackmat style start to compete against humans! Would you allow MindCuber more than 15 seconds of "inspection" and race just the solve? ;-)
