What are you working with, Togo5? Are you planning on making a self contained bot, or is it going to be a auto-remote control?
I have a few suggestions since I've had in the works a similar project for a little while now, done some trial and error. (I even had the very first security bot I made stolen). But posting suggestions with out knowing your plan, might overwhelm this thread so. Do you know what you have in mind.. some wish list of the specs, features, sizes, might be useful.
