I have not heard of such a thing. If it existed, I would not want it on my boat. There are way too many ways this could go terribly wrong, since your electronic nav system has, in the final analysis, very limited information.
I love my electronics
and gadgets, but sometimes you've just got to use your eyeballs and judgement.
Actually, I do recall
a custom system for autonomous sailboats that used AIS
for collision-avoidance. And that's the only place I would consider such a thing: on a robot-boat small enough that it could not damage anything else.
[edit:] Here's a link to an autonomous AIS collision-avoidance research
paper. The author suggests that this would be valuable on crewed vessels: http://www.jsps.go.jp/english/e-ronp...13-NRF-Nam.pdf
I've seen other research
, this was just the first readable one that popped up when I googled "autonomous AIS collision avoidance".
Here's an abstract of one with more detail: http://www.ion.org/meetings/abstracts.cfm?paperID=164
