And don't be surprised if you and your team members get so hooked that you find yourself spending more and more time on the robot just for the fun of it...
My team starts off meeting Monday-Thursday, 7 to 9 (p.m.) and on Saturdays from 9 a.m. to until about 5 p.m. As the weeks progress, it goes from 6 to 10 (p.m.) and Saturdays will push back as far as the janitors will keep the school open and as long as the adult supervising the room can stay (I'm usually that adult on Saturdays, and I'm easy to convince to stay). Two years ago, we really started enforcing a time limit on meetings and we found that having a time limit on the meetings seemed to help focus students on doing the work that needed to be done.
If you still think you'll need to do some convincing of your team members, try showing them some of the existing teams' websites; often they have photos posted of their teams in action. Team 116's photo site can be found here:

I really hope you can convince your team to participate in FIRST, not only because I think FIRST is wonderful, but also because I'm excited to hear updates on how your team advances!
