Agree or Disagree: The Role of Agreeableness in Decision-Making with Multi-Robot Teams
SessionLBR3: Late-Breaking Results
DescriptionWith the increase of human-robot collaboration, understanding its dynamics becomes crucial for improving teamwork. This study examines how robot agreeableness and presence of multiple robots influence users’ decision-making and perceptions using the Desert Survival Situation task. Forty adults participated in a mixed-design study, where the number of robots was a within-subjects variable, and robot agreeableness was a between-subjects variable. Participants selected survival items for a desert environment, with robots supporting or challenging their decisions. In Phase A, participants interacted with a single robot with 50% agreement. In Phase B, participants interacted with one more robot in addition to the same robot with 50% agreement, where participants were divided into two groups: one group interacted with a highly agreeable second robot (80% agreement), while the other group interacted with a highly disagreeable second robot (20% agreement). The two phases were counterbalanced. Results showed that participants were more likely to change their decisions when interacting with a team that included a disagreeable robot. However, participants perceived the team with an agreeable robot as having higher human-robot fluency and a better understanding of the team’s goals. Regardless of robot agreeableness, participants preferred two robots, with 11 participants highlighting the benefit of additional perspectives for better decision-making. The number of robots did not influence decision changes. These findings emphasize the importance of balancing robot agreeableness and leveraging team-based interactions in human-robot collaboration because using multiple robots inherently improves the collaborative experience, and the agreeableness of these robots significantly affects decision outcomes and team fluency.
