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 without the bushing (I apologize in retrospect for the 3x3
inverted interlaced block of rtl10: ProjectX :)

It's really a question of what people have. Not everyone has a DDK (though
I think lots of people did eventually succomb to the $39 DDK eventually) so
it's hard to spec a part like that. It's usually easier to use a part
that's in the RIS package, like the 8422 wheel hub, for example.
If we go by the mindset that we want a game that could be played by poor
little Timmy with his single RCX, then no, but we could also use the
"substitute with your own colour as long as you can make it work with a
event standard grey one" type of ProjectX rule.

Overall I'd like to start working these issues and start debating because
I'd like to firm up rtl11 rules soon. I'm sure this will be a topic at
dinner the week after.

If you can find the "opponent" flag on your territory and manipulate as
noted above, then I'd be very impressed. I would be concentrating more on
my own flag. It's a valid strategy to destroy the opponent flag- I think
Chris said not to "hide it" which I took as "eat it" inside your robot.
Cinderblock at rtl3/4 did exactly that-it would take opponent marbles and
dump them out the side of the arena. If you can do it, more power to you.

I think Chris meant (and I wasn't an active participant in that discussion,
I'll admit) that the robot can't leave a wagon train around the flag,
effectively. Attacking a competitor is more than welcome, though, I think,
again, we'd be overestimating the ease of FINDING the competitor to attack them.
