[robocup-humanoid] Discussion at the Robot Soccer WS at the Humanoids 2007

[Jacky Baltes]

Hi,

my thoughts on the dribble kick.

I think the striker should have as high a chance of scoring as if this
situation occured in real soccer. Goalies would need to react very well to
make a save.

The problem with the 15sec. rule is that teams will implement goal keepers
that continuously block, wait 15 sec, go up, and repeat.

I think it is easy to judge if a kick is on goal or not, but if a more
precise definition is wanted I would suggest that a goalie has to remain
upright until the striker kicks the ball in such a way that it enters the
goal box. The goalie is then allowed to fall to block the ball, note that
this does not mean that the goalie has to wait until the ball has entered
the goal box.

This makes it much harder for the goalie since it needs to recognize the
position and approx. velocity of the ball, but I think this is warranted for
this challenge.

CU,
   Jacky
