A fairly far fetched robot was in the news recently: Future Surgeons May Use Robotic Nurse, ‘Gesture Recognition’.
ScienceDaily (Feb. 3, 2011) — Surgeons of the future might use a system that recognizes hand gestures as commands to control a robotic scrub nurse or tell a computer to display medical images of the patient during an operation.
I believe, partly based the insightful comments given at Nursing Advocacy, that it is not a good idea to replace human scrub nurses with robotic ones. It would be much better to solve the shortage of nurses). In this case, there is so much a scrub nurse does, so much more than a robot can do, for at least the next fifty years or so.
But there will be a publication in the Communications of the ACM soon. That will be an interesting read
Update: There is already a nice video about the story on the ACM site (here).
