I originally suggested the thread/sleep() scheme, but after
thinking about it more, I really like the generator approach in
the case where you want to explicity end each robot's "turn"
using the CPU (which is what the sleep() call does).

OTOH, if you want the robots to wait for events of some sort
(e.g. from a queue) or data from an I/O device, then threading
is probably the way to go.

I guess it all depends on whether the robots' behavior is to be
time-driven or event-driven.
