Library robots

There's an article in Backbone magazine that tells all about the University of British Columbia's automated storage and retrieval system (ASRS), aka the "library robot". It's a system that uses a computerized crane and robotic arm to retrieve books requested through the online catalog (Voyageur). The article was brought to my attention by a govdoc listserv posting from a librarian in Washington state who says his state is very interested in using something similar and who wants to know if any FDLP libraries (especially regional depositories) are considering installing library robots.
