Oh yeah, structural foam is the bomb. We also put wooden dowels inside tubes - the REALLY SMALL bit of added weight is nothing compared to the massively increased structural stability; I swear RaPHael (our robot last year) would have had its tube-based arm destroyed many times over if it wasn't for the wooden inserts!
And Henry, unless you know something I don't know (I won't discount it, I didn't go to the drive train meeting), we've always had our aluminum frames TIG welded by Randy Baden - remember "Randy the Welder"?
Also I want to give a shout-out to team 456, it's always a joy to see what you guys come up with every year - so far "Captain Hook" has been my favorite. Can't wait to see you again at Lone Star!
