Personally, if someone came up to me and said our teams robot was too well made to be made by us, i think it would be a complement. I know for a fact our robot was student made, i watched them make it! The only thing that really wasn't student done was welding some of the major frame components together, and that wasn't because they didn't want to try, but because our adviser didn't feel comfortable with any students or even himself welding the critical parts.
Also, dint think a team with a college student or students means they do all the work. My team mainly used me as a soundboard and another source of suggestions for designs. Design and engineering was a very collaborative processes between the mentors and the students. Any work i did to the robot was being an extra set of hands or doing stuff like helping drill holes or do other small stuff. Biggest single part i did on the whole bot was a 2 axis camera mount that no one had a clue on how to build. So please don't stereotype us college students as primary builders

Ive been dieing to do something in FIRST for about 7 years now, and this is the first chance ive gotten. So for as much thanks from my team for helping them, i thank them twice as much for giving me the chance!
