Would You Obey an Aggressive Robot: A Human-Robot Interaction Field Study

Abstract

© 2018 IEEE. Social Robots have the potential to be of tremendous utility in healthcare, search and rescue, surveillance, transport, and military applications. In many of these applications, social robots need to advise and direct humans to follow important instructions. In this paper, we present the results of a Human-Robot Interaction field experiment conducted using a PR2 robot to explore key factors involved in obedience of humans to social robots. This paper focuses on studying how the human degree of obedience to a robot's instructions is related to the perceived aggression and authority of the robot's behavior. We implemented several social cues to exhibit and convey both authority and aggressiveness in the robot's behavior. In addition to this, we also analyzed the impact of other factors such as perceived anthropomorphism, safety, intelligence and responsibility of the robot's behavior on participants' compliance with the robot's instructions. The results suggest that the degree of perceived aggression in the robot's behavior by different participants did not have a significant impact on their decision to follow the robot's instruction. We have provided possible explanations for our findings and identified new research questions that will help to understand the role of robot authority in human-robot interaction, and that can help to guide the design of robots that are required to provide advice and instructions
