We are a combined team. In Bremen, we got our robot very late, and its
camera was broken. So we sent it back without damaging the joints :-). In
Dortmund, they had at least two broken joints.

Let's just say: the half time will be long enough to change the uniforms.
The schedule will not be as tight as in previous years, e.g. the
preliminaries may be 4x6 games in the Nao competition and 4x3 games in the
AIBO competition (vs. 56 games in the previous year).

In addition, I think the teams will be smaller than four robots, because
that number does not seem to be realistic anymore.

The basic idea is that the teams playing share their uniform parts, so one
team gets all the blue parts and the other all the red parts. Unless we are
only able to play with two robots per team, in which case each team has
enough uniform parts in both colors.

About the screws: they are the first part we would like to change (also the
ones that close the battery compartment). We made very good experiences with
Torx screws, and for screws that are (un)screwed quite often, they seem to
be the better choice. I guess the original screws have to be replace anyway
after a short while.
