Quite impressive package. However, I could see possibilities
for the collision detection external to the sub for avoidance in
an environment with unknown dynamics. [ or am I missing a
point here? ].

I recall a neat litle program in the early 80s called "Rocky's Boots"
involving a sub or hydrobot.  It doesn't compare with today's programs,
but PCs back then had 64K limits at 5-8mhz and large pixels, so
it wasn't bad and was fast compared to most.
