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:
- Get rid of the gears and motors in the arms and replace them with decent servos, maybe something like the Power HD 1501MGs?
- Motor controller for each robot is going to be L298 based.
- 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.
- 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:

my design has 22500 oz on the arm,not going to need that much ,but will use a lot less current them any other servo,on the arms and hands using 407 oz servo's i got my 407 oz servo $69 on sale ,made by HITEC Power HD are good servos ,i used them before
couple of other points on that servo if its 219 oz thats stall torque First so you need to look at real lift torque witch is 75% of it,second at 219 oz divide by 16 = 13.6 lbs and 12 inch arm you are looking at 13.3 divide by 12 = 1.14 lift and most arms are 24 inches so looking it can lift less then 1/2 lb.
Wow, 2000 Oz inch is quite a bit! I was trying to find a decent Hitec servo with a good Oz inch rating, but I haven't had much luck (with a decent price I might add). What Hitec servo did you get?
not 2000oz i made mistake 22500 divide by 16 to get lbs its 1406 lbs then 12 inch arm is 117blb and my arms are 24 inches so total my hand can lift is about 60 lbs
its a digtal servo,need to find the part #
here is a link to my project
my omnibot 2000 project nickname 6 millon dollar robot,and not because of the cost,named it after his strength
I was looking at your thread a few times, it looks like the Hitec servos you have are discontinued, and the next one I saw that came somewhat close is the HS-7995TG. That coupled with a servocity spg400a with a 5:1 ratio would allow me to lift something around 5lbs, which is more than enough for what I need.
Yes thats the one you can use,i have some of them in my lynxmotion johnny five project 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
Hi there Omnibot aficionados, wow a whole world has just opened up to me reading your threads. You all seem so amped and focused on these little fellas its kind of contagious. I have recently inherited one of these and was fishing around for some info and this is my first port of call. I have just read the instruction manual and am about to have a go at re charging the battery to see if it fires up. Has any one got ant sage advice or tips and tricks at this stage. It was dusty and I cleaned it with a damp cloth and gave it a visual inspection. Everything looks in really good order as its been sitting in a box in a garage for about 25 years. The only thing missing is the microphone, Everything else in tact.
