[robocup-humanoid] Manual Kick-Off

[Oskar von Stryk]

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
