Well, I DO use cad for doing first designs on my bots, and I try to have an idea of what I want to build first. I have already gone through the starting stage for roboteering, and entered my last feather into RW (most of you know what happens ) And I entered the FW smash with a robot before that. If you are coming, or if anyone else is coming to the RC wars event, then Ill show you some videos of me trashing a 6kg industrial bin with Big Daddy. Like it or not, this bot IS safe.
