The latest episode of the Robots podcast interviews Kristinn R. Thórisson from Reykjavik University on some of the great advances, but also some of the disappointments of artificial intelligence, and where he thinks AI will be used in the future. In the second part of this interview, we conclude our quest for a definition of the word "robot" with a definition by Prof. Wendelin Reich from the Swedish Collegium for Advanced Study at Uppsala University, Sweden. He defines a robot as an artificial, physically embodied ‘agent tool’ - and gives some good reasons for this definition. For details as well as a list of other definitions have a look at the Robots website.
