We have a rotating duty schedule for students and mentors that works pretty well assuming no catastrophic robotic issues.

Student #1 - Leadership - Primary responsibility is to talk to people.
Student #2 - Safety Officer, usually a mechanical or electrical team member
Student #3 - Technical, usually of a specialty that is different than the Safety Officer.

Often there is a mentor or two on duty.

We also have a mechanism for keeping students out of the pit that aren't supposed to be there, this is especially problematic after a match when the driveteam is also trying to hand the robot over to the pit crew and get away from the congestion.

Every student on our team is given "G tokens" (Named for Mr. G, head teacher and drive coach). They are used a currency for a reward system for our trip. Spotted doing something awesome and a mentor hears about it you get some, likewise spotted doing something not so awesome we take them. At the end of the event there is a bonus given to the student(s) with the most tokens.

Our experience is that making students responsible for a tangible currency keeps them on their toes and on task. As a mentor, catching students doing awesome stuff and being able to reward them on the spot also creates memories.

Edit: One thing to also remember is tell kids to take a break, eat, relax, or otherwise decompress as no one can be "on" for three days straight and not suffer some ill effects.
