Quite true.

I've done that several times this season, including this interesting CNC sheet metal shoulder bracket for our robot's arm which bolts right onto an IFI 72t sprocket.

But when you're in the elimination rounds and a critical part on your robot fails, you don't always have the time to create drawings and have the on-site machine shop fabricate a new one. In that case, I'd rather teach a younger student to be make up a creative, MacGyver-like solution out of a few bent up pieces of Lexan, some Gorilla glue, a hose-clamp, and an empty Mountain Dew can. (Or any other random stuff in the pits.)
I've been inspired for real engineering during the build season and on the playing field, but the inspiration I found in the pits is often for creative thinking and intuition.
