as for the failure mode. i would expect that the failure mode for 1/8 inch tube would be bending, however i would expect the failure for 1/16 tube to be bending in or getting crushed. especially if the robot takes a hard hit from the side. i think 1/16 is a LOT easier to parallelogram too.

Crushing from impact (and to a lesser extent parallelogramming) are really a result of poor design in this era of mandatory bumpers.

We've never crushed in our 1/16" wall with some brutal impacts while using bumpers. Without bumpers, the exposed corners often get smashed badly, but just the corner and it's purely a cosmetic issue. If we ran without bumpers, we'd beef it up. However, we know we're using bumpers and take advantage of it.
