After several years of saying I'm going to build a robot for a competition, I finally decided to go for it at the beginning of September. Mech Warfare looked like the sweetest thing since I saw it a few months ago on Botjunkie.com.
One of my main goals for this project is to learn more about electronics and programming. I have been exposed a bit to both before, but I still don't really know what I'm doing in either. Hopefully I can take away some new knowledge from this project.
After much research I decided that I'd buy a Bioloid kit since it comes with enough servo's to make a good bot and I would be able to try out a walking robot before I start designing the rest of my robot, since I've only dealt with wheeled robots before.
Edit <Added pictures of my Bioloid adventures>
The first thing I did when I got the Bioloid kit was build the humanoid, which was pretty cool. I spent a day or two playing around Robotis programs. I installed Roboplus and made some pretty cool actions.
I found it really hard to get the biped walking good, so i decided I would start off with a quadraped since this is my first step into walking robots. Here is gen 1 quad:
I didn't quite like my setup, I wanted to bring the legs in a little closer so I rebuilt it using the same sort of setup that the ankles of the bioloid kit has, I also added supper bouncy balls as feet since I thought it would be cool:
I didn't like the lack of freedom the legs had though, and this was when I decided that I should make my bot like an Immortal from Starcraft 2, bringing my other hobby of playing video games into my hobby of building robots
The shoulder joints are all very close to the center, and the legs can extend out very long.
Starcraft 2 unit "Immortal" in the map editor:
I have used this to analyze what basic shape the Immortal has, and its walking animations. I didn't really have very high hopes on the walking animation actually being useful, since its an video game and not the real world. I decided to use the Bioloid motion tools to make it walk like the immortal anyways, and it turns out that it worked REALLY well. I will post a video when my card reader gets here. It is pretty much the sweetest thing ever, although I am slightly worried if I'll be able to program it.
Here is the video of the immortal mock up walking:

I tried to keep to the shape of the Immortal as close as possible, just because I think its cool. Eventually I want to put some sort of shell on it so it can look just like the real thing.
After I proved that it could walk, I started making the actual design in SolidWorks, it is by no means complete yet, but here is the current progress (as of this post):
Question - Are those target plate position legal (red squares)? I know the rules say they have to be on your turret if you have one, but I don't want to add more weight to the turret . Although I know that the legs might interfere with the targets. Right now I am looking at having 2 tank guns, one on each side of the turret. If anyone has 3d models for those tank guns, it would be helpful!
The majority is either purchased parts or sheet metal parts that I will probably have bigbluesaw.com waterjet for me. I have limited access to tooling in my apartment so outsourcing the majority is required. I plan on buying a small brake to bend all the brackets.
My next steps are:
Finish CAD Model
Learn how to use my Arbotix
Buy a soldering Iron (I'm not even sure what I'll have to do electronic wise)
Thanks for reading!
