First of all, you can't discount the fact that they are younger kids. I'm not saying that they can't keep their focus , but it is more difficult with younger kids. I believe that you are a good team leader just because you are taking the initiative to post here in an attempt to learn. If there were a lot of rookies, then they may not have understood the commitment necessary and may have been burnt out a little.
maybe next year...
-If it's a problem of getting started, take each group and give them chart paper. Have each team write draw up what they feel is important to have on their robot.That's what we do in FRC and it is a good thing even down to FLL.
-Make sure all of the kids understand the time that needs to be put in
-Set a slightly easier schedule, and have way points that you want to hit by each meeting.
-Don't be hesitant to tell them where they are going wrong and be stern in correcting it. I'm not saying yell at them but tell them they needs to get back on track and stay focused if they want to be successful.
