Yeah, I don't think it should be too difficult to get the camera working. It's just hard to get consistent pixel values so that we can determine which colour each sticker is, especially since it depends so much on the lighting conditions of the room it's in. I think I'm going to play around with...

Hi all, Here is Skewbot, our second year engineering design project. I designed this robot along with Matthew Hill, Matthew Kneed-Teed, Jiang Yuan and Matthew Pierre. It was done using Max Jiang's (turtwig's) solving code. It uses a programmable Arduino and a ton of 3-D printed parts...

ANOTHER UPDATE: It works... we fixed a couple of soldering connections on the PCB, and now it works great (with a few slight misalignments here in there). We still can't quite get the camera to read in the colours of the cube yet, so for now, I'm doing it manually. But we tried a couple of test...

So the Arduino code is like 95% functional now (besides a few angles that may have to be adjusted a bit), our only problem is that when we started soldering wires together and used the PCB we made, only half of the motors worked. :confused: :? maybe we just did a poor soldering job, or there are...

We're actually using a Javascript solving program and HTML file given by another user on this site, Turtwig. For now, we can input the colors into his website and get a solving algorithm that we can manually input into the Arduino program. Eventually, though, we would like to use a Python...

Cool, view the spoiler at your own risk, it's over 400 lines :p So the code is kind of unfinished and is extremely inefficient right now. I have 12 different sub-functions being called into my main function, 'setup()', that all correspond to a different set of motor rotations, and I used them...

Here is a picture of us beginning to build the initial prototype. At least now you can all get a better idea of what's going on. There are 3 servo motors to grip the cube and 3 stepper motors to turn it. It's not perfect, but it should serve it's intended purpose once we work out a few kinks...

Yeah, it turned out pretty nice, although we made 2 adjustments to the model and it's actually a bit smaller and more compact now. I didn't have a huge part in designing the claws, though, that was mostly my other teammates, Matthew Hill and Matthew Kneed-Teed. We've made a lot of progress...

Thanks for the advice, I'll definitely make sure I consider all of everyone's suggestions! and good luck with your project as well, it sounds really interesting! Also, I've been emailing with turtwig and we've been trying to incorporate his Skewb solver into our project. It should be doable...

Yes, so it will consist of a cube rotation (which is just twisting both sides at the same time), then rotating the cube from the bottom claw, doing the move, and then doing the previous moves in reverse. So basically its using setup moves. I guess if you consider rotating the bottom claw a move...

Yes, that was what I was talking about when I said that some rotations can take 5 moves. In order to reach those corners, the whole cube can be rotated by rotating both of the side claws at the same time.

If anyone wants to comment anything on this, please feel free, it would be a great help even if you feel you don't have 100% clarity on what we're trying to achieve. Just try to answer the questions from your perspective, whether you're just a cuber, a designer, a WCA delegate, you're...

The bottom claw both rotates and opens and closes and so do the 2 claws on the sides. The Skewb is sitting on an angle on the bottom claw, and if you release the side claws and have the bottom rotate a certain amount, it can reach 2 other corners. As for the program, we only need something...

We're conducting a survey based on the prospects of this project and what you guys think so far based on the information that I've posted. I know there's not much to work with, but it would be helpful if at least 5-10 people made an attempt to participate. Post your responses below. Questions...

The robot can do any move on the cube, but certain moves can take up to 5 different robotic turns functions to do. :p So theoretically, if I use an optimal solver, an 11 move scramble could end up being 55 'moves'. 50% of moves only require 1 robotic turn, but 50% require 5 turns (if a corner...

This is a prototype of the claw that holds the cube from the bottom. We made a lot of changes to this for a number of reasons and the new claw parts are being printed. We're using the same design for all 3 claws, but the shape of the plates that grip the cube are different for the bottom claw...

This is a drawing I made at one of our first meetings a few months ago. A lot of minor changes have been made and more detail has been put in since then, but this is somewhat the idea. The servo motors squeeze the arms of the claws together and the steppers rotate the claws. There are 3 claws in...

You're right. Our design is a little different than that though, because we technically can access any of the corners because our robot design is capable of rotating the cube (sort of). It's hard to explain without showing a picture. I'll upload one in a minute. I'm going to think of using a...

It's not necessarily the code itself that's making it so inefficient, but the way that the robot solves it mechanically. We only actually have 2 claws that are twisting the cube, and those claws only have access to 4 of the corners. Therefore sometimes the puzzle has to do 5 turns where a human...

Hello, I am working on a Design project with 3 other 2nd year Engineering students from Canada, as well as a 2nd year Computer Science major. We are planning to build a robot that can take a scrambled Skewb puzzle and solve it. We've been working on this project for 3 or 4 months now, and are...
