Dear Teen- and AdultSize Teams,

Thanks a lot for this pointer, Sven!
It may be that they deliver only to Germany and Austria.

The beach handball is quite soft.
After RoboCup in Graz last year almost all balls which
had been unused before the tournament were severley damaged
with heavy scratches from robot feet after the competition.
Also these balls do not roll straight very well.

Sounds like a very good idea!
A widely available real soccer ball and one step further towards
FIFA rules.


@AdultSize Teams:
If it is ok for you we can put this ball in the rules for 2010.


@Sven:
Did you every try this ball with your TeenSize robots
whether it would be feasible for them also?


Best regards,
