“…Thus, having presented the classical line of reasoning arriving towards the utility of equipping robots with natural language capabilities, and having discussed a space of possibilities regarding role assignment between human and robot, let us now move to the second, more concrete, albeit less general avenue towards justifying conversational robots: namely, specific applications, existing or potential. Such applications, where natural human-robot interaction capabilities with verbal and non-verbal aspects would be desirable, include: flexible manufacturing robots; lab or household robotic assistants [30], [31], [32], [33]; assistive robotics and companions for special groups of people [34]; persuasive robotics (for example, [35]); robotic receptionists [36], robotic educational assistants, robotic wheelchairs [37], companion robots [38], all the way to more exotic domains, such as robotic theatre actors [39], musicians [40], dancers [41] etc.…”
