Adapting Autonomous Behavior Using an Inverse Trust Estimation

Robots are added to human teams to increase the team's skills or capabilities. To gain the acceptance of the human teammates, it may be important for the robot to behave in a manner that the teammates consider trustworthy. We present an approach that allows a robot's behavior to be adapted so that it behaves in a trustworthy manner. The adaptation is guided by an inverse trust metric that the robot uses to estimate the trust a human teammate has in it. We evaluate our method in a simulated robotics domains and demonstrate how the agent can adapt to a teammate's preferences.
