Trust is a key factor in ensuring acceptable +human-robot interaction, especially in settings where robots +may be assisting with critical activities of daily living. When +practically deployed, robots are bound to make occasional +mistakes, yet the degree to which these errors will impact a care +recipient’s trust in the robot, especially in performing physically +assistive tasks, remains an open question. To investigate this, +we conducted experiments where participants interacted with +physically assistive robots which would occasionally make inten- +tional mistakes while performing two different tasks: bathing +and feeding. Our study considered the error response of two +populations: younger adults at a university (median age 26) and +older adults at an independent living facility (median age 83). +We observed that the impact of errors on a users’ trust in the +robot depends on both their age and the task that the robot is +performing. We also found that older adults tend to evaluate +the robot on factors unrelated to the robot’s performance, +making their trust in the system more resilient to errors when +compared to younger adults.
