I have no clue yet to as what to name my bots, but I do know someone should probably ban me from EBay! I will end up with 3 total when it's all said and done.
Okay so what I want to do with at least two of the bots is to add a Mini ITX setup, one I already have which runs windows 8, 8gb ram, and a 120gb ssd. I figured that the 3rd omnibot 2000 I can use for parts or whatever..
For powering the onboard pc's I figured that using a pair of 12vdc 7 amp batteries should be enough to run the pc for at least a couple hours? There will be another battery to run the EZ-B as well as other electronics. IS there enough room in the base for the batteries?
I would love to get some input on this project, as I mentioned in another post I also have a CNC Mill which I have recently started using again, and even though I am not that good with it(It's been a long time), I would think I can fabricate some parts if need be. I usually use either 1/8" or 1/4" think pvc plastic for milling.
Today I received my first Omnibot 2000, one of it's arms is broken and the first thing that happened is that it smelled so bad that it was taken completely apart and is currently in the dishwasher. I think it was living at a kennel with a bunch of dogs for the past few years, loaded with hair and all sorts of interesting things. I had to change after it was that bad.
A couple the things I want to do:
1) Get rid of the gears and motors in the arms and replace them with decent servos, maybe something like the Power HD 1501MGs?
2) Motor controller for each robot is going to be L298 based.
3) Single Microsoft USB Lifecam HD camera on each robot - I found that the tracking on these is fantastic compared to the one that comes in the EZ kit, especially where lighting is an issue.
4) servo Pan/Tilt for the head, maybe using Lynxmotion servo brackets?
There's a bunch of stuff I am still working on but most of the items I mentioned above I already have on hand.
Here's a couple of pics of the 2000 I got today:

JOSH omnibot project uses it.
Small problem it does use a lot of power,in my setup it uses a lot less current and i think the cost it less too.,dont have to use a high torque motor,there are few others at lower torque.
Second stays stead up or down with the power turn off,on SPG400a or others you cant do that
check out my omnibot project for ideas

As much as I keep trying to keep this close to stock looking, I was looking at servoblocks from servocity, you could make a pretty decent arm(they can attach to the spg400a's), has anyone used these?
After I get the shoulder done, the next thing to figure out is the elbow, i've seen a few different ideas, I was thinking of mounting a servo inside the elbow, but I don't think it would be strong enough....
If I could mount it inside the body, using standoffs and drilling out a couple mounts on the spg400a, it might work........
I use a small aluminium plate and some like to use fiberglass resin,only its hard to work with and needs to work outdoors
Best about using aluminium plate,easy to work with,high strength,low cost and if standoff breaks like on fiberglass ,it can be easy to fix or change .on fiberglass it cant be fixed
most of the SPG models you can have them add pot instead of doing it your self
all gearboxes or servo's have a feedback on the servo it needs to be removed and the 3 wires longer and add a feedback pot to final gear,its always on the final geat going to a arm or wheel or horns .
most likely it is
The SPG400A's I purchased as kits, already had the servos(PowerHD 1501MG's), they include a trim pot with the kit, so I only had to 'slightly' modify the servo: remove the servo trim pot, modify the servo for continuous rotation, make a notch on the servo body to run the wires for the trim pot through, then solder the trim pot that was included with the kit, it really works good..
on any other type you need it,its called closed LOOP system on continuous rotation its called open LOOP SYSTEM
from photo i couldnt tell,and didnt know you new about it
looks good so far ,i guess you will add aluminium i said to the plastic ,so it wont stress under load
A very good example is the HEATHKIT HERO robots i also have ,i just oered a new robot #79 TOTAL
Thanks,
