What types of metal do you use for your robot in general?
This year we constructed most of our robot using 1"x1" aluminum tubing. It worked, but we had numerous problems: warping from over tightened bolts, extra holes needed to help guide and tighten bolts, etc. I know every year can be different, but what types of metals (and in what shapes and forms) do you mainly use and for what reason? We know the basics: aluminum being lightweight, steel being strong; heavy; and prone to rusting, etc.
Thank you for taking time to help!
