Words of warning: Beware the human element. When you try to micromanage people, you'll be amazed how much less work they'll do. No matter how perfect your organization, there will always be people who don't follow or (worse) resent the system.
My advice:
Divide the kids up by what their talents are (programming, mechanical, electrical, etc) and assign a leader to each subteam. Then delegate tasks to the subteam leaders, who can assign tasks to their subteam members. That way the organization is spread out over several people, each an expert in their area and each able to oversee their own tasks to completion.
