Right. I can see the two motors connected to port B will slide the axles and
switch the drive train from "fast" to slow.

...But I don't see how LBump will detect the opponent.
Or better yet, how does it know when it loses sight of the opponent?
If you can explain this, then I'll buy a book.
In theory, the whole design of this robot is very good, and would work very
well, but in pratice... I don't think it will work as expected. That's why I'm
curious how these designs have done in competition.
