A relatively new area within information systems is the design of robotic healthcare. This narrative review considers the question, how does one ethically design an elderly care robot? To answer this question, robot ethicists consider the ethical impact of robots, how designers ought to design robots ethically, and how a robot design ought to be, so its behaviour is ethical. The latter consideration defines another field of study, machine ethics. Machine ethicists ask, how does one design a robot information system to behave ethically? Thus, robot ethics is concerned with the ethics of design practice, whereas machine ethics is concerned with the ethics of the product designed. The findings from this narrative review point the way forward to how one can answer both questions with a new design approach that is grounded in care and professional ethics, value sensitive design, and the integration of two machine ethics schools of thought.
