For example, this robot will be able to remind the patients that it's their time to take their medications. Of course, robot will be able to respect their decision if they do not want to take medications, and it will remind the patient again after some time. In addition, this robot will be able to contact the doctor if something goes wrong with the patient.

Researchers at the University of Connecticut are trying to develop a robot that uses ethics, and in order to create such a machine, they are using a machine-learning algorithm that should determine robots actions. This robot would be able to "learn" and become ethical (and therefore 'rational') based on your decisions.

As you can see, ethical robots might be available someday, and we might even see them in our local hospitals.
