4 KudoZ points awarded for this answer. Comment: "Thanks Sergio Although your link is interesting, I think this is not the same use of "pose" that I have in my text. The article you quote would seem to be relevant exclusively to anthropomorphic robots. In the end I left "pose" unchanged and wrote a note for the author, but I have received no feedback as yet. I think it would be safer to leave the dictionary slot empty for the present. Regards Derek"
