Human-robot collaborations (HRC) can be used for object detection in domain search tasks, which integrate human and computer vision to improve accuracy and efficiency. The Bayesian sequential decision-making (BSD) method has been used for task allocation of a robot in search tasks. In this paper, we first provide an explanation to reveal the nature of the BSD approach: it makes decisions based on...
A human-robot hybrid cell is developed for performing assembly in flexible manufacturing in collaboration between a robot and its human co-worker. Robot trust in human is considered, a computational model for the trust is derived, and a method to measure and display the trust in real-time is developed. The collaborative assembly includes robot-to-human handovers of payloads (assembly tools). A novel...
Recently, lightweight and flexible robots have been introduced for human-robot collaborative manufacturing. However, most of the research in this field focuses on the physical aspects of the interaction only. Nevertheless, psychological and social impact of human-robot collaboration (HRC) on manufacturing needs to be addressed and embedded in the design as well such that the robot actions become acceptable...
In human-robot collaboration (HRC) for assembly, a robot needs to use its onboard vision systems to perform many sensing tasks. The robot's observations may not be always reliable due to erroneous sensing caused by limitations of the detection systems and disturbances. Hence, additional observations made by the robot or the human co-worker seem to be necessary. However, too much human involvement...
In this paper, a novel approach to the human-robot collaborative guidance and navigation of autonomous vehicles is proposed. The switched linear quadratic regulator (SLQR) is utilized as a method of determining when control of the autonomous vehicle should be switched from autonomous control to manual teleoperation or vice versa. This switching is determined by a quadratic cost function that takes...
Mutual trust is a key factor in human-human collaboration. Inspired by this social interaction, we propose to analyze human-agent mutual trust in the collaboration of human and (semi)autonomous multi-agent systems. Human-agent mutual trust should be bidirectional and determines the human's acceptance and use of autonomous agents as well as agents' willingness to take human's command. It is especially...
We consider domain search tasks using autonomous multi-agent teams collaborating with a human operator. A Bayesian sequential decision-making strategy is first proposed for the optimal allocation of manual and autonomous sensing mode in the presence of sensing uncertainty. However, this type of optimal strategy is not always the style of human decision-making. In particular, regret has been shown...
