Chiyah Garcia José Lopes Helen Hastie School of Mathematical and Computer Sciences, Heriot-Watt University Edinburgh, United Kingdom Paper Link ABSTRACT Increasingly complex and autonomous robots are being deployed in real-world environments with far-reaching consequences. High stakes scenarios, such as emergency response or offshore energy platform and nuclear inspections, require robot operators to have clear mental models of what the robots can and can’t do. However, operators are often not the original designers of the robots and thus, they do not necessarily have such clear mental models, especially if they are novice users. This lack of mental model clarity can slow adoption and can negatively impact human-machine teaming. We propose that interaction with a conversational assistant, who acts as a mediator, can help the user with understanding the functionality of remote robots and increase transparency through natural language explanations, as well
