[robocup-humanoid] Manual Kick-Off

Hi everyone,

let me use Oskars example:

Team A manual positioning, kick-off
Team B game controller

If now team A must not move for 10 seconds but team B may already start, we
could say "team B is allowed to execute the kick-off".

Then we still might have a robot handler starting team A robots on the field
when team B is already playing.

Also I do not really like the referee moving the ball. Usually he will use
his foot and throw a shadow on the ball and on the field. To what direction
is the ball moved? Might that give an advantage to a team?


But a really easy to handle idea would just be granting the kick-off to team
B in every kick off/dropped ball situation. So team A would have to set all
robots back to own penalty area on every kick off. We would not need any
other (complicated) rules.
The robot handler will start them from behind the goal line/ground line. So
the robot handler is outside the field and won't disturb the autonomous
robots.

Autonomous kick-off will be a big tactical advantage no matter if you play
against teams setting up autonomously or manually. Newer teams do not have
to develop quick and dirty solutions for not getting punished. Kick-off
rules will be easy and won't lead to many violations.

Best regards, wish you a happy new year!
Jörg Zimmer

Hi Jacky,

I understand your proposal as follows:
Let Team A use manual kick-off (and not the referee box) and
let Team B use the referee box for kick-off.

If Team A has kick-off and when the referee blows the whistle or gives
the signal "Play" then Team A has to wait for 10s,
while the referee moves the ball imediately and sufficiently to signal 
team B that the ball is in play.

If Team B has kick-off and when the referee blows the whistle or 
gives the signal "Play" then Team B has to wait for 10s
no matter if Team A has already moved the ball.

This means that all teams using manual kick-off must implement
a way that after the "Play" signal of the referee the robots wait for 10s
bevore they start moving. (They can move their head but not their legs 
during the 10s.)

This sounds OK to me.

In addition we need some kind of penalty if a team (no matter if using 
manual start or the referee box) is permanently violating the rules for 
the start of play.

Best regards,
Oskar
