Robot librarian

According to the New York Times, Johns Hopkins is developing "a robot that can move about inside a library and locate a book requested by a user, take it off the shelf and carry it to a nearby scanning station." The idea is that eventually they'll have another robot at the scanning station that can find specific requested pages (a tough job!) and scan those in, to display remotely to the person who requested the information. Pretty cool. (There are, of course, various intprop issues to be resolved here, but I think they're not insurmountable.)
