Humn... I've designed a few systems this year using numbers taken from the Inventor models of the kit made by Autodesk. I think this is FIRST's substitute for the drawings this year, and I can't say I wholly like it. I'm having trouble trusting Autodesk for demensions of critical systems in the bot, but I've tried to verify some numbers with a caliper, and I haven't found a mistake yet. Perhaps when everything is built, and it all fits together, we can get used to trusting Autodesk in the future. Still, if you use numbers off the model, I'd sugget checking a few easy ones yourself.
Anyways, I pulled some numbers from the Autodesk model and put them in the attached picture. You can get the model here:
