Before the robot V
Well watch the animation several times, and then have several people come and think of different parts of the robot, see what follows the rules and breaks them.

make sure you have someone checking the rules, write down questions that you can look for in the rules or report to FIRST.
Ask any quesstion that comes to mind and be ready to change things. Listen to all ideas, because you can take something and use it even from the craziest ideas.
Dont spend too much time on the design.
and remember HAVE FUN!!!
Hope this helps.
