The inevitable increase in real-world robot applications will, consequently, lead to more opportunities for robots to have observable failures. Although previous work has explored interaction during robot failure and discussed hypothetical danger, little is known about human reactions to actual robot behaviors involving property damage or bodily harm. An additional, largely unexplored complication is the possible influence of social characteristics in robot design. In this work, we sought to explore these issues through an in-person study with a real robot capable of inducing perceived property damage and personal harm. Participants observed a robot packing groceries and had opportunities to react to and assist the robot in multiple failure cases. Prior exposure to damage and threat failures decreased assistance rates from approximately 81% to 60%, with variations due to robot facial expressions and other factors. Qualitative data was then analyzed to identify interaction design needs and opportunities for failing robots.
