In this talk, given by Anton Nijholt, we survey and comment on research that deals with humor as it can be generated and understood by physical social robots. Ultimately we want to investigate whether humanoid robots can play the role of a stand-up comedian. Such a robot uses humor in its interaction with the audience, rather than in face-to-face communication in a humorous or joke-telling context with an individual. Clearly, we can expect that telling jokes and have humorous interactions with an audience requires knowledge (or intuition) of how to present humor in verbal and nonverbal ways, whether it is in face-to-face interaction or with an audience that provides global and collaborative feedback. We survey human-robot interaction research that deals with humor.
