My team is very dedicated. Why? Well, for one we have a very vigorous acceptance process. Only the most interested students are allowed into Robotics, and they have to show their interest throughout one school year by entering into engineering contests and etc.

It's sad to hear your team is not dedicated. Try to make meetings fun and offer lunches to them or something. Good luck. Find any teacher who will help you. Find a physics teacher.
