Re: pic: 1501 Final Robot - see you at BoilerMaker!
The entire body and arms are .040" aluminum. The rear trunk lid is .090". There are two 1/8" steel plates that our uprights are bolted to. The uprights themselves are also .040" aluminum. There are NO bolts holding any of it together, only rivets.
When you bend aluminum around a form or into c-channels you increase the rigidity of the aluminum. You than rivet the pieces to each other or to sheets to get the maximum strength. I'm just the CAD mentor so I don't know the whole theory of monocoque assembly. I do know that the arm can withstand tremendous twisting or bending forces.
Hope this helps.
