It seems like you skip by that rough aluminum step. I know you use a lot more CAD than we did, but do you just trust that your Vex and cardboard dimensions are "good enough"? Or do you end up rebuilding some manipulators if you find that your dimensions don't work as well as you anticipated?

We prototype until we get the critical dimensions. The prototypes that merit it, get more detailed work. Last year we did a 1:1 fully functional version of the entire intake + kicker out of old robot parts and sheet metal. You can see this in our 2010 video.
Some stuff goes right from cardboard into CAD into sheetmetal...
