We did a pretty unique construction style this year.
For the drivebase we used large plates of 5052 sheet metal supported by 0.5x0.5" with 1/16" thick wall aluminum tubes riveted on at the edges.
The reasoning is that our team, where we machine everything in house, doesn't have access to a precision CNC break. We can't bend sheet metal accurately enough to construct a chassis out of it so we just riveted on tubes at the edges to strengthen the plates.
The shooter was constructed using 1x2" VersaFrames and lots more of 5052 plates, riveted together so that the channels were again at the corners and edges of the large plates.
Different student on the team have different design styles so our robot ends up looking pretty radically different each year (just my design style changed from 1x1 VersaFrame everything to 1x2 and large plates this year).
