We too are a two year school (Tech Center) in Michigan. We have only one returning student from last year. The rest of our team is new. They have everything as their roles. Our team is small also, just 12 or so students. They do the machining, electrical, cabling, programming, design, drawings, etc. They do it all. We have 1 CAD student, 4 machine tool students, 4 electronics/networking students, 3 programming students. We have 4 teachers, 3 returning graduate mentors and 1 engineer to guide and make sure no one gets hurt. It is a nice team. More returning students would have been nice but they all graduated but the one.
