Have you tried approaching school officials about your team becoming part of or affiliated with the school? Also are you looking for/expecting funding for your team from the school board? I don't want to come across as negative (my team also has it's own issues concerning the school) but I included this link
http://www.chiefdelphi.com/forums/sh...t=26255&page=3 because as soon as your team is affiliated with others things can become sour. You must decide how much of an affiliation you want first. To get them involved there are excellent points in some of the previous posts. You may also ask if you could demo the robot at a Board of Ed meeting or invite school officials to YOUR robot meetings. Let them know and possibly see how much goes into building a robot and how much the team means to your members. Make sure they also see not only all the effort that goes into physically building a robot but all the fundraising and PR that also goes with sustaining a team. Don't forget to play footage of actual comps whether your robot is in it or not so they see what the idea of FIRST is.
Good luck,
Jason
