Go to Post In real life (IE when you go to apply your engineering skills to tasks in industry) there will be constraints on all sorts of things - many of which may or may not be "fair" or even "intelligent". You must learn to either work around them or use them to your advantage - preferably a bit of both. - OScubed [more]

It does not necessarily have to be fancy, it just has to be functional. Remember, function over form.
I didn't say a thing about using it in the drivebase. Superstructure is the part of the robot above the drviebase. On our robot, we use 1 1/2" x 1" x 3/4" tubing for the drive frame and key superstructre (masts for arms, for example). 3/4" thinwall is used for stuff where we either need it to weigh nothing or we don't really care. It is pretty strong though. 330 used it for ramp framing last year. It supported about 140 lbs, often charging onto it, and we were more worried about the corrugated plastic being gouged than we were about the frame. I just wouldn't recommend using it for a drivebase.
