[robocup-small] Ruling on move to Double-Sized Field

[Joydeep Biswas]

Dear Fellow-RoboCuppers of the Small-Size League,

The survey responses to the change of field size are as follows:
11 responses: Voluntarily for RoboCup 2014, Compulsorily for 2015.
6 responses: This year, at RoboCup 2014.
2 responses: At some unknown future RoboCup.

Based on these responses, we will be adopting the change of field size
Voluntarily for RoboCup 2014, Compulsorily for 2015. The double sized field
will be exactly twice the area of the old field size, for a dimension of
6050x8100mm.


   1. There will be four double-sized fields, one for each group.
   2. For every game, if both teams accept to play on the larger sized
   field, the game will be played on the larger field.
   3. For a team to qualify beyond the round robins, they must successfully
   participate in the double-sized field technical challenge.
   4. Each team must submit their preference of field size at least a day
   before the scheduled game time, failing which the double-sized field
   preference will be assumed.


Double-Sized Field Technical Challenge
Successful participation is declared after scoring at least 2 points.
Points will be awarded for the demonstrating the following skills on the
double-sized field, where each skill is scored only once:


   - Taking a kickoff without a force-start (1 point).
   - Scoring a goal against a stopped defense consisting of centrally
   placed goalie and 2 defenders (1 point).
   - Taking an indirect free kick from the goal line without a force start
   (1 point).
   - Scoring a goal on the stopped defense after a pass between two robots
   (2 points).
   - Scoring a goal on a moving 3-robot defense after a pass between two
   robots (4 points).


In addition to these points, additional bonus points will be awarded to
teams that play on the double-sized field for actual competition matches:


   - You get 4 bonus points if you played at least 1 game on the double
   sized field.
   - For every goal scored in your best double sized field game you get 3
   bonus points.


Procedure for the Double-Sized Technical Challenge:


   1. The challenge starts with a kickoff.
   2. If the team successfully scores a point from the kickoff, the
   challenge continues according to the normal rules of the game, except all
   free kicks are awarded to the playing team.
   3. If the team is unsuccessful at scoring a point from the kickoff, they
   may request another kickoff in lieu of a free kick the next time the ball
   goes out of play.
   4. The challenge concludes at either the 5-minute time, or when the team
   withdraws after scoring at least 2 points.


Regards,
The Technical and Organization Committees of the RoboCup SSL, 2014.
