Haven't posted for a while on LMR, but that doesn't mean I'm not working on a robot! I've researching the heck out of circuitry and components that I need for my latest project. The chassis is built and the insides are coming together. I don't want to post it just yet, but it's name is I-CORA. Since my background isn't in electronics, I've been reading books and teaching myself logic circuits and PICAXE. With three kids and a busy job it takes a few weeks to get thru a book. I have several I"m reading now to try to get smart enough to get design the circuitry I need.
