Takes up less room too. Can't imagine building in 1/2" tubes in aluminum. Would fold like tinkertoys. Steel is super strong.

Yes, steel is heavier, but we just use less.

Agree to disagree here. Aluminum is lighter and we use more of it.
We have had quite a bit of sucess with welded aluminum extrusions. We build robustly, and even in the toughest years for robot impacts (2014) we still have a robot to show for it. I think most of us remember how bad the hits got in 2014, but Jeffrey survived two regionals, Archimedes division, Einsteins, IRI, R2OC and Robofest. We're playing defense against our practice bot this year with that robot. Aluminum holds up if you have enough of it.
I don't think I've seen steel robots in this area though, its definitely unique.
