Go to Post I would go even further and say always hate your robot. Keep breaking, iterating, and trying to figure out how to change the robot from week one of build season to champs. - saikiranra [more]

Re: Q. Best sheet metal design?

Unless your worried about corrosion resistance, stick with 6061 sheet.

We typically use 1/16" plate (0.063) unless there is a need for something heavier. If your bending 0.125" sheet you will definitely need to have a larger bend radius on your sheet metal brake to not induce stress cracking.

The vast majority of sheet metal designed robots use 5052 .09 or .125. I assume he is suggesting make robots similar to 148 or 971 that use sheet metal extensively for almost all their parts. They also limit the amount of welding and use rivets for most of their fastening. Teams have had success using 1/16" 6061 but from what I gather you have to be a bit smarter at your design then with .09 5052.
