An important consideration in human-robot teams is ensuring that the robot is trusted by its teammates. Without adequate trust, the robot may be underutilized or disused, potentially exposing human teammates to dangerous situations. We have previously investigated an agent that can assess its own trustworthiness and adapt its behavior accordingly. In this paper we extend our work by adding a transparency layer that allows the agent to explain why it adapted its behavior. The agent uses explanations based on explicit feedback received from an operator. This allows it to provide simple, concise, and understandable explanations. We evaluate our system on scenarios from a simulated robotics domain by demonstrating that the agent can provide explanations that closely align with an operator’s feedback.
