[robocup-humanoid] Seven "Size 1" Soccer Balls

[Achmad Subhan KH]

Dear all,

since i found the ball in the sport store in our country i got several information.
I try to share about ball size those available in the store.
There are two kind of mini-ball, both have same type "mini" and also mention each size on the balls.
I attached the picture, one is mini-ball size 0 and the other one is mini-ball/skill ball size 1.
according to the picture the blue one (smalest) is size 0, it is have a diameter about 13-15cm, and the other one is white with grey color combination ball, it is size 1 by diameter about 18cm (see in the IMG5544).
I think the statement that mention in the rule it mean mini-ball size 0 (refer to diameter).
it is more easy to find the ball in the sport store and ask to the seller mini-ball...size 0. 


Best Regard


Subhan Achmad

Hi，

I ask sales staff to measure the diameter for Size 1. It is about 14cm in diameter.
I had asked the field team to purchase the ball in advance.  


Best,
Mingguo
