[robocup-nao] Final Nao rules for 2008

[Michael Quinlan]

Hi Stefan,

Point 1:
 -  So I agree that teams with get up routines should be allowed to use 
them (and should gain an advantage). I would teams to inform the referee 
at the beginning of the match if they posses to ability to stand up. 
When a robot falls over it is then given sufficient time to stand up 
before being penalised (if it fails).
 - I also like the idea of moving the robots to the side (basically the 
same as the ball out of bounds). For example they would be moved 
sideways (to the opposite side from the ball) and also 1m from backwards 
away from the ball.

Point 2:
  - This is hard one to get right (and we are open to suggestions to 
make this better).  It depends on how much value we place on robot 
safety, I for one don't want to see my robot broken because another 
robot fell into it. BUT I also love to see robots competing for the 
ball, how to achieve this balance is difficult.
  - I would probably add that the keeper can not be called for violating 
the 50cm rule when it stays inside the penalty box. Maybe this is the 
case where the offensive robot has to kick the ball or its penalized for 
being within 50cm of the keeper.

Keep the suggestions coming ...
