Hi Chris,
> This is one of the most directly useful posts for my own project work.
Great!
Re-reading the post last night I was really aware of 1) all the typos
(sorry bout that) and 2) how much I had to leave out. I really was
aiming for a BigBird-describes-subsumption-on-a-3x5-index-card but
it turns out that there's just too much to cover. Hopefully the
post will ellicit discussion and I'll have a chance to clarify
all that is missing. Steve has encouraged me to write up a
tutorial for robots.net, so perhaps that might grow out of this
as well.
best regards,
