These instructions will help you turn your pile of Kitables Rubisolver parts into a working Rubisolver.


It's very important that you read through the instructions and follow steps in the right order. If you glue something together in the wrong order it may be very difficult to continue assembling the kit or you may have to break apart parts which will make you a sad panda. All the code is available open source and we encourage you to PAINT, UPGRADE, REDESIGN, AND MODIFY AT WILL! HAVE FUN!

Step 1: Take Stock

Before starting make sure that you have all of the parts you need. If you are missing any components please contact Kitables immediately at info@kitables.co , so that we can get you back on track ASAP! There are a lot of small parts included, so we recommend doing the project in a clean area where you can find those stubborn dropped washers.

• 46 Laser Cut Wood Parts
• 2 medium length #4 screws
• 6 long length #4 screws
• 12 short length #4 screws
• 2 #4 unthreaded spacers
• 28 #4 washers
• 20 4-40 nuts
• 1 Microcontroller
• 1 USB cable
• 6 jumper wires
• 2 servos
• 2 tubes of super glue
• 1 Rubik's cube

Recommended Tools

• 3/32" Allen wrench
• Needle nose pliers
• Paper towels
• Hot glue gun (optional)

<p>Works perfectly. I used Parallax's Continuous Rotation Servos, which requires some code changes to get them to work. Check out their documentation here (http://learn.parallax.com/KickStart/900-00008) for the requirements, but basically you need to change all the servo.write methods to servo.writeMicroseconds and change the values for the motion positions. (For example, centered is 1500... make sure you trim them to that position as well!)</p>
<p>This was a fun project. I took it a step further and made the machine fully autonomous. I wrote a program that uses a web cam to take snapshots of each side of the cube and uses a home-brew look-up table to recognize the cubelet colors. The string of colors is then uploaded to the Arduino board and the cube solving process starts.</p><p>Link to video: https://www.youtube.com/watch?v=Wvht6fjCdzk</p>
<p>That is Awesome!!! We love to see what you guys come up with </p>
<p>I am not able to buy from your website</p>
<p>jeffsalim1, we now have kits available: <a href="http://kitables.co/kits/rubikscubesolvingrobot">http://kitables.co/kits/rubikscubesolvingrobot</a></p>
<p>Can I have the laser print documents.</p>
<p>Any way to get a little more turn out of the turntable??</p>
Hi Mashall, you can adjust the range of the turn operation by adjusting the values of the servo driver function in the provided Arduino code.
<p>Requiring that we glue directly to the servos seems to be a terrible design. The super glue doesn't bond well there, it's awkward to apply it, and there's risk of damaging the servo by gluing it to itself. These two places should be snapped in with a plastic piece that fits nicely in the grooves on the servo.</p>
Hi scoop. We are gathering that feedback for future updates. the current problem is that the servos will drift over time and alignment must be more accurate than a single gear tooth.
<p>To get my Mac to recognize the arduino clone included in the kit I had to install drivers for the CH340G chip. I found them at: http://blog.codebender.cc/2015/06/12/new-stuff-updated-mac-drivers/</p>
<p>I see the new image added to the instructable, of the parts with part numbers. Great addition! Will there be additional images/segments involving the assembly of the individual parts?</p>
<p>Hi Fred, Thanks!</p><p>Sorry for the delayed response. We'll keep adding pictures and editing instructions until it's clear for everybody :) Are there any steps in particular that would be helpful to break out into more detailed exploded views?</p>
<p>Re-examining the numbered parts list shows that there's no real reference for those numbers. As an example, I can see that part 1 and the three part 21 pieces go together, but parts 5, 7, 8, 9 mean what parts? There's other reference numbers, but they aren't printed on the parts and there's no clear identification. Even a document resembling the scan I sent of all the pieces, with arbitrary part numbers written in, followed by a paragraph or ten for assembly would be useful. Example: glue 3 part 21s into part 1.</p><p>More details would be required for the rest of the construction, I believe.</p>
At present, I've given up on assembling the device. I'm going to continue to hope that the assembly process will become clearer over time, at which point, I'll take up the project.
<p>I've recently received the Kickstarter update that indicated a higher resolution video here on Instructables. My computer automatically kicks it to 1080p and it's a much clearer video for seeing the parts. My original problem remains, however. The clear video shows the first steps include three &quot;bridge-shaped&quot; pieces, yet my kit contains only two. The parts count in the list above indicates 45 pieces, which is the count I have, but that's missing the third bridge. It's a shame to be stumped on virtually the first step.</p>
<p>Hi Fred,</p><p>I've attached an image of the part I think you're describing. We regret that it looks like some of the kits may have gone out with only two of these parts. It's possible to get the kit assembled with only two by leaving a gap between the two and gluing the parts separately to the large top piece (let me know if this isn't clear), but if you like we can rush mail you the missing part to get you back on track to assembling your kit. Thank you for bringing this issue to our attention.</p>
<p>That's the piece, yes. I recently purchased some hobby grade plywood and plan to trace one part over it, cut it on the scroll saw and sand to match. I'm hopeful that can proceed with the construction based on the higher resolution video.</p>
<p>I actually didn't use the third piece... in fact, my kit was missing it as well... I just glued the two to the outer edges of the board instead. You could also use some of the washers to space it out to keep them from collapsing in on each other.</p>
<p>I'm sure that would work. I had considered taking scrap pieces to accomplish the same thing, but I also like the idea of having a reason to pull out my scroll saw and make more sawdust with it.</p>
<p>Hello, I found that Item number 21 has one piece missing, I got only two of them, can you ship it to me ASAP so that I can start building it?</p>
<p>I see in the Kickstarter comments that an instructable for assembly will be released soon. If this is that assembly guide, may I suggest a bit clearer section for the mechanical parts? Eighteen seconds is not particularly long, even using the pause feature of the video, and the detail is lacking, even in full screen mode.</p><p>My kit arrived today and I expect to have little trouble with the assembly, but it does not appear that it will go together as clearly as other KS projects I've received. Emblaser/Laserblade is an exceptional example of top-notch instructions.</p>
<p>Thank you for the feedback and for purchasing a Rubisolver! I totally agree that video resolution is far too low. I'll work on getting a higher resolution video uploaded ASAP. It looks like the Emblaser instructions are locked down to Emblaser customers with an invitation code, but if you have a direct link I would appreciate the resource. Please let us know if you have any issues with the assembly so that we can make these instructions as clear as possible.</p>
<p>What a coincidence! I just popped off an email to you folks. I don't know if the Emblaser people would want to have that material &quot;out in the wild&quot; so I'd have to check with them before I comply with that request. Perhaps a single shot of one of the pages would not be out of order. I'll work on that and send it via email. I think they put as much work into the manual as they did into the project, it's that good. As noted in my email, I have been responsible in the past for creating instructional documentation, so I tend to be critical (in the positive sense of the word) when it comes to this type of material.</p>
