Abstract
The capability of executing proper recovery strategies for different types of error situations is important for collaborative robots implemented in everyday lives. To understand people’s perception on the effective robot reaction to robotic failure, we conducted an online study where we asked participants to rate seven different robot reactions to handle three different types of error situations. An analysis of the result shows that in general, robots that employ error recovery strategies are rated significantly better than those who ignore the error situations. The strategy in which the robot expresses its regret for its own errors had the highest average rating in terms of anthropomorphism, while the strategy in which the robot apologises for its errors had the highest average likeability and perceived intelligence ratings. Further analysis show that the recovery plans are rated better if implemented in planning errors compared to social norm violations. Finally, we found that user’s gender and personality traits significantly affect participants’ ratings on error handling strategies, which suggests that personally-tailored error handling strategies might work best for future collaborative robots.
