I have larbin listed in my webbots page as relating to the URL http://pauillac.inria.fr/~ailleret/prog/larbin/index-eng.html (don't ask me to remember why :-). I've seen a variety of robots come out of ...inria.fr, which is a French research institute.
For anyone who's interested, by webbots page is http://www.jafsoft.com/misc/opinion/webbots.html , although it's not as current as the discussions here.
