If you're a freshman, don't be really obnoxious and not do anything. The upper-classmen will resent you for it, and they're already inclined to harass you because you're freshmen already. If you ARE an annoying freshman, work hard and share food with people. People will still be annoyed, but you're less likely to get strangled by the end of week 4 of build.
We saw both sides of this on our team, mostly with the freshman guys. We had 3 freshman guys. 1 showed up maybe twice, CADed a side of the crate, and then goofed off the rest of the time instead of doing his work, all the while cursing up a storm and giving people lip. The other two goofed off a bit and would make inappropriate comments, but they CADed up the entire robot and brought food. The girls were much more pleasant to work with. So yes, I am talking from experience.

Also, I'm not calling all freshman annoying or obnoxious, just calling out those who are. This applies to older guys too, but the newbies on the team are much less likely to call you on it if you're twice their size, at least in my experience so far.
