That's too bad..
it's frustrating having a team that isn't motivated to do anything. Last year the majority of our team was new, and most people weren't really into robotics until AFTER they had gone to the competition and seen how sweet competitions are.. (I was new too, but I heard enough robotics stories from my brother and dad to know that it was a pretty cool thing
) we had a pretty small group of people last year who consistently were at meetings and were actually productive when there.. I'm sure this year we still will have the people who just don't care, but I think some people will become more involved after having experienced one season..
My only ideas for you would be to show them some video/pics from competition or maybe get some past team members to come to a meeting or two and talk to them..
I doubt this helped much, but good luck with your team anyway
