The color pink

Greetings! This is Casey again.

Some vigilant readers pointed out that the color of the waistbands is pink and not magenta. As I said: I'm not really watching for these, so please forgive me for this little mistake.

But now to the important things:

Today I quickly scampered away while the humans were sleeping or slacking off (see that earlier blog entry). I met some teams of the other leagues (after luring their humans off into a storage room and locking the door). There are some really nice bots around here and I think you should get to know them too.

The first ones I've met are the ones of the small size league. They are playing soccer as well on an six times four meters big field. When they are playing it's always like watching a sworm of zerglings (or colony of ants if you're more familiar with that). They are playing in teams of 5 robots, which are watched by cameras from above. They are working together with a controlling computer, which is located off of the field. The controller watches the game by using  cameras, gives his team hints about where the ball is located at and where to drive. These robots use wheels for moving and achieve quite a impressive speed and acceleration. Even for their small size.  While chatting, they recommended me to visit the middle size league, which is two floors above ours.

The robots of the middle size league are like the big brothers of the small size league. They are moving on wheels as well, but are playing soccer on a much bigger field. They play in teams of six using a eighteen meters long and twelve meters wide field. The robots  reach quite impressive heights, so they can carry their own PC's and laptops. Each one carries at least one camera, usually providing an 360 degree field of view. Of course they are packing quite a punch, making them shoot the ball through the whole hall from time to time. Their acceleration is impressive as well. During the German Open I watched one of their goalies shredding pieces out of the wooden goal when he decided its better to enter the goal from the solid side instead using the front opening. They are also the first robots who learned to propel the ball up into the air and hit the goal in the upper corner. Hmmm maybe I should try that, too.

I spotted more walking robots as I returned to my floor. The bigger one is playing in the teen size league. We were chatting about several walking techniques and stuff. He told me that the teams in his league are all looking different. They are all designed and build by their human team members and play soccer as well in a field like ours. Hmmm maybe I should ask the biggest one of them to join our team. He covers the whole goal area when he sprawls out.

The smaller one is a member of the kid size league. They are a little bit smaller than the the teen sized ones - at most 30 centimeters high while the teen sized ones might be twice as high. The teen and the middle sized leagues are playing with at most three robots on the field, like we do. I was watching them for a while and I have to admit that they are walking quite fast for two legged robots. For the moment I can't keep up with their speed, but I'm sure I'll improve my way of walking till next year.

OK, I think I should return and wake the humans now. We still got work to do!
