Can we assume there will be something like a bushing at the top of the
axel? Otherwise we would need to build a gripper that can grip a bare
axel fairly well in order to lift the flag. ie:

      888                                          8
      888 <- bushing                       8
      888                                          8
        8                                            8
        8  <--- bare axel ------------>  8
        8                                            8
8888888888                       8888888888888
8888888888 <- tire -------> 8888888888888
8888888888                       8888888888888

this (preferred)                      not this

With regard to the choice of wheel - will it have a tire on it or not?
Can I suggest using something other than black, such as the grey tires
from the Droid Developer Kit? I suggest this because I suspect that
with an 8" gap between the tables, a number of people will be using
tank treads or the large wheels - black treads either way. It might be
too difficult to distinguish if we don't use a different colour.

On the subject of not being allowed to deploy blockers, what about
decoy flags? I would suggest not since this could easily make the game
impossible unless decoys were required to be a colour other than that
of the flag.

Another possiblity... we can't hide the flag, nor block it or shield
it, but what about turning it on it's side? Tipped over on it's side
and placed near the edge or, better yet, corner of the table would
make it very easy for an opposing robot to accidentally push it off
the edge, thus causing the opposing robot to be disqualified and
requiring little or no effort on the part of the "winner"  - other
than casually knocking the flag over and then backing away so as not
to be accused of blocking.

On the subject of no blocking or guarding or other sematic... you have
suggested that it should be OK for a robot to, in a sense, attack a
competitor by pushing the opposing robot. I would argue that
deliberatly placing your robot in front of an opponents for the sake
of pushing them is effectivly a form of blocking, albeit (presumably)
at a greater distance from the flag than just sitting in front of the
flag. Some kind of definition is needed to clarify when a robot is
blocking/guarding/call-it-what-you-will and aggressively pushing a
competitor back.

(...) I don't see it as too hard to build a mechanism that grips just the axle (rubber bands around the pincers for example) but I'm sure sooner or later someone will try building a proof of concept and realize how incredibly hard it might be (...)

With the lack of any upcoming train event, I feel a some what shallow victory. On one hand it is sad that the train heads will not soon be bantering in this news group with drivel of mountain clearance height, 3 wide or 10 wide, or just how many (...)
