Rubik's cube Robot solver

Thank Kas, I will try to find out more...

Hi,
@mrgakoy96 please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

How have you got the servo connected?
Can you post a picture of your project so we can see your component layout?

Can you please tell us your electronics, programming, Arduino, hardware experience?

Thanks.. Tom.. :slight_smile:

Dear, Kas and Tom.
This is component layout of me, and programming. I use Arduino UNO R3, I entered through Arduino's serial monitor but no any feedback from serial monitor and servo. Code is CubeMover13_posted and done uploading.
Code is CubeMover_hard_coded_demo: Run Good.
Please help me!!!

Hi,
Have you got the negative/gnd of the servo powersupply connected to the gnd of the UNO?

I can see it in your picture...

Tom..... :slight_smile:

Yes, I did gnd of the servo powersupply connected to the gnd of the UNO but still as before...I was wrong???Help me!!

Well its not shown on the picture.
Have you got any of the servos to work?
Have you just connected one servo and written some code for it?
Do you have a DMM, what is the servo power supply?
Tom.... :slight_smile:

Dear, Tom!
I have a 5v power supply, all running, when I test a simple code it runs normally, and the code CubeMover_hard_coded_demo provided by kas also runs very well but when running Code is CubeMover13_posted code is not.
If you have video tutorial, I thank you very much...

Hi,
I can't help you any further, sorry, I am not familiar with the Rubics Cube code.

I only ended up here through some magical forum transformation, I was originally in a thread on

"help for servo control "power base shield"

:o :o :o :o

Thank Tom very much

I have the LinkSprite cube solver kit (a blatant and shameless copy of the project here).

The servos included in the kit were junk so I replaced them with servos from DFRobot. Big improvement!

My problem is the cube gets 'pushed' around after a dozen or so moves and then it gets hung up in the opposite claw. Eventually two layers are grabbed at the same time, then chaos ensues.

Any body have any clues to solve this problem?

This mess can be generated by several factors

  • bad claws relative position
  • inaccurate 90° rotation
  • insufficient claw/cube grip

Please post a video showing a typical hung up

Thanks!

Your claws are too low


Move each wrist servo holder plate 2/3mm upward

The key moment is at 0:10
(for slow motion, set YouTube video speed to X .25)

At this very moment, is the cube seated on the base of the claws??

I will shim the holder plates with washers and report the results here.

Hi Kas,

can you please send me the android app you used to solve the cube through the web based server?

I'm am now planning on how I'm going to make the cube solver but i want to have all my software ready before i buy the parts for cost reasons.
i originally thought of making a color sensor rotate on a servo reading each square individually but it would take alot of time to finish and since i already have an android phone.. it wasn't cost effective.

Thanks!

Please remove the txt extention after downloading the files

how do i open those files and with what program?

Hi joashsamual

How do you plan to build the gripper, CNC or 3D printing ??
Let me know

Hello Kass!

I just finished the hadrware part of my project (for school) , the only thing I still need to work on is the

final version of the software, altough I have no idea how I should start making this....

And I need to handle it in 3 weeks for school :o :confused:

Can you write me in a short message or mail how I should begin making this? (I already read the entire forum and didn't find anything useful)

Thanks in advance!
