I've used Santa Clara University Library robots, (listed in this article), but I don't think these are a good idea at all. You go to the library computer, look up the book you want, and press 'retrieve', and go to the desk. A minute or so later, the book shows up. When I go to any other library, I browse the books on the shelves, maybe 20 or 30. I can quickly shuffle through them, maybe looking at just their spines to see what I want. These robots just kill browsing completely. I think they are fine for some purposes - archives, but not for university general libraries where browsing should be encouraged.
