This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.

Here is another of my projects.Will more info. I have changed his head to a clear dome.Blue strip around neck is EL...

Rb550f's Super Omnibot
This one of my 10 robot projects.This is ready for ezb v4..It has all of the original features of omnibot 2000.New drive...

Jeremie's Fridgebot
This isnt a new robot but rather a remix of an old idea I had. Its based off of a robot that I built for a 555 timer...
Ok here is a placement pic I was thinking of , I will try the bot with one motor first.
This is the backup plan if I.need a little more torque..

So since I'm upgrading the main omnibot motor I figured maybe I could do the same thing with the regular omnibot gearbox. Once agian the motor is slightly larger , shaft is the same as well and I tested the motor that came in it stock and it has good rpm but not much torque.@robotmaker do you think its ah good idea to upgrade these motors too?
I'm thinking about getting 2 of these and putting one one each side/ corner of the base so it gets close to the wall and flips the dust bunnies in front of the main brush.
I'm.looking to get 4 of.these , does anyone have these instead of getting them on eBay?
i think i have them,they called a side brush tore apart over 35 roomba's to use the main board and chassis for a TURTLEBOT and then sell the rest of it,on ebay and yes i would upgrade both,just to be shore you have enough torque always good to have more then less torque
backup plan looks good,can easy add motors in parallel ,but in servo's in tandem is much harder,what happen if even they are sync very good,if one wears out a little or misses a step or ? then both will go bad,better to use a gear box to get the torque you need or a higher rated torque servo
JOSH i bought another omnibot ,not the 2000 model so i may have gear box left over if you need that one too,one omnibot using EZB the other one full restore
also on the MIG welder i got in it wont weld aluminium stress stress stress first is needs more amps,but important is it needs shielding gas 100% argon plus a special spooler gun because aluminium bends easy,so i sent the other back and looking to get another MIG welder or modify one rated at 180 amps so be awhile if anyone need aluminium welded
Only helium ARC welders can do alumimum correctly, I should have said somthing. That's "tig" welding with tungsten. Mig is wire and welds mild steel , copper , brass, and up to 10 ha sheet metal.
jstarne1, you can order up to 5 side brush modules directly from the iRobot website. They cost $15 each. Here's the URL: http://store.irobot.com/product/index.jsp?productId=2822991&cp=3744764.3358508&s=A-ProductAge&parentPage=family
I made another set of replacement treads for omnibot 2000 if anyone wants them
JOSH ALOT OF BODY SHOPS use MIG welders to correctly weld aluminium here is a link to extreme4x4 video on welding aluminiumthey use it on all aluminium parts on a car this site EXTREME4X4 is also on tv also my friend who owns a body repair shop,and i use to help very while back on building and restoring very old cars use a MIG welder also easy to convert any mig welder to a TIG welder,many links on the internet some MIG welders are made and setup for only welding aluminium ,but then they are over $1000 just need to change a few pieces and add a special spooler gun for aluminium ,plus shielding gas check out the video also talks about the different types of aluminium extreme4x4 show
i use to watch that show alot on SPIKETV,i guess i missed this one
if i find the side brushes witch i think i have can do about $5 each and includes the shipping
