Computational Model of Robot Trust in Human Co-Worker for Physical Human-Robot Collaboration

Trust is key to achieving successful Human-Robot In- teraction (HRI). Besides trust of the human co-worker in the robot, trust of the robot in its human co-worker should also be considered. A computational model of a robot’s trust in its human co-worker for physical human-robot collaboration (pHRC) is proposed. The trust model is a function of the human co-worker’s performance which can be characterized by factors including safety, robot singularity, smoothness, physical performance and cognitive performance. Ex- periments with a collaborative robot are conducted to verify the developed trust model.
