RoBoT

What is the definition of a “robot”?

There are many definitions of a “robot”. The classical definition among my colleagues is “a robot is a machine that senses, thinks, and acts”. For about 10 years I personally have added “communicates” to these three – recently other people have also been saying “…senses, thinks, acts, and communicates”. But for better or for worse, this definition makes most modern household appliances – clothes washing machines, etc – robots.
