Do you think there will be a robot in hospitals? If you go to a hospital in London, you'll see a new doctor there. He is very clever. He can work 24 houts a day and never gets tired. He is Dr Robot.
Doctors often need to ask their patients a lot of questions, and it always takes them a lot of time to do that. But Dr Robot can ask patients questions for an hour if it is necessary. With the help of Dr Robot, a human doctor can have a lot of useful information when he meets his patients.
How can Dr Robot do this? A computer "tells" him what to do. Dr Robot can do a lot of things that people can do, though he can't completely replace human doctors.
