Hi all

           Fine

    David> WALLS
           Fine

    David> LOCAL VISION
           Fine

    David> RESTART RULES
           Fine

    David> OFFICIAL COLOURS
           Fine.

    David> GOALS
           Fine.
         
    David> BALL
           Fine.

    David> VIRTUAL ENERGY BUDGET
           Fine.

    David> PHYSICAL ENERGY BUDGET
           Fine

    David> INCREASE NUMBER OF ROBOTS
           A

    David> CHIP KICKING
           B.2   


    David> LENGTH OF PERIODS / TIMEOUT / HALFTIME:
           B

    David> RED CARDS / SAFETY ENFORCEMENT:
          
    David> Implementation:
    David> 1) When a yellow card offense occurs, the game is stopped. (as per normal)
    David> 2) A yellow card signal is sent from referee box to team host computers. (as per normal)
    David> 3) The team host computer that received the yellow card must move a robot to the field
    David> peripheral so that it can be physically removed by the robot handler.
    David> 4) The game continues as per normal
    David> 5) The robot must sit out for at least X minutes (current proposal is 2 minute). On the
    David> next game stoppage after X-minute, the robot may be placed back by the robot handler
    David> (no signal from referee box will be given). The yellow card status will be checked only
    David> at the instance stoppage occurs. For example, if a stoppage occurs 1 minute 55 second
    David> after a stout, the robot cannot be put back in 5 seconds into the stoppage. This is to
    David> prevent teams from delaying stoppages so that they can get their robot back in.

    David> Note: The referee box needs to be modified so that it can keep tracks of all yellow card
    David> status.

    David> Suggestions for offenses worth a time penalty:
    David> ----------------------------------------------
    David> You could give a time penalty when
    David> - The two defender rule is applicable
    David> - a robot bumps into another "on purpose"
    David> - a team couldn't take a free kick for the third time in a row
    David> - a robot enters the 50mm radius at free kicks (restarts) for
    David> the third time so the free kick need to be restarted
    David> - a robot kicks the ball from the throw-in directly or almost
    David> directly off the field repetitive, so the game gets stuck.
    David> - a robot loses parts bigger than a screw

    David> Advantages over yellow/red card system only:
    David> --------------------------------------------
    David> - The decision for a time penalty is easier to make  for the referee. It penalizes
    David> misdoings without taking the
    David> chances for the affected team to win. - After the penalty is over. The misdoing is
    David> forgiven, no further    discussion
    David> - For the case of a wrong decision, there is no need for discussion since the time
    David> penalty is quite short and won't turnaround the game (If a team has a lot of misdoings
    David> then this would be a disadvantage    for the team and that would be okay then)
    David> - The game could get more fluently since you take out a robot and don't have to stop the
    David> while game, with all robots taking their
    David> best position again. (Sometime you will have to stop the game because the robot that
    David> has to halt is in the way, but then you
    David> could "halt" the game and restart it without a "stop" so that all robots are still at
    David> their positions when the game goes on
           Fine. 
          
           We suggest to implement this rule by the refer box. When the
           misdoing team receive the "Yellow Card" signal,they must
           react to the signal and drive one of their robots out of the
           field and hold there still. After the penalty time finished
           ,when the first "Stop" signal is sent,the refer box should
           also send a "PENALTY TIME OVER" signal to the punished team.
           And the punished team can react the signal and drive the
           robot in the field.
           
           If the punished robot moves in the field during the penalty
           time, a "Yellow Card" should be given again.   


    David> FREE KICK/KICKOFF PROCEDURE:
           Fine.
           We suggest all restart should be 50mm inside the field.
