[robocup-small] new ball.

[Chris Parker]

     I like the idea of a new ball that would be hard to get moving  
like the bullets that we saw this year in Osaka.  A suggestion that  
was made by a member of our team in the past was to use a standard  
orange floor hockey ball.  These are made of vinyl and are designed  
NOT to bounce (so that the after coming down onto the floor after a  
shot, they STAY on the floor), are a little larger than a tennis ball  
and are bright orange.

     With a larger ball, we could relax the convex hull rule  
somewhat, which would allow for more varied approaches to dribbling  
and kicking.
