Re: What types of metal do you use for your robot in general?
Attempting to synthesize all of the responses, it seems to me to come down to:
- Take advantage of your expertise. Whether it's woodworking, monocoque, steel, sheet metal work, fiberglass, carbon fiber, or whatever, leverage it. Experts in any decent material can out perform people trying to wing it in the best available material. If you are so lucky as to have experts in multiple materials, may I suggest a bake-off? (and express a bit of envy, as well)
- If your team does not have real mentor expertise in a construction material, aluminum (6061, 6063, 7075 extruded and tempered or 5052 sheet/folded) is a good place to start, with baltic birch plywood and sheet steel as alternates when aluminum doesn't fill the bill.
