Computational ethology-based human behaviour modelling: first investigation for Human-Robot Collaboration

Human-Robot Collaboration (HRC) has been proposed to add flexibility to traditional production systems. Digital Twin (DT) has been integrated with HRC for safety collaboration. The human behaviour model is an essential part of the DT. This paper aims to identify a research gap and possible solutions for human behaviour modelling in HRC. Therefore, this paper reviews human behaviour studies in HRC and ethology. The results show that the current HRC focuses on recognizing and monitoring human behaviour, but a deep analysis of human behaviour is still lacking. Computational Ethology (CE) has the potential to be applied to HRC to model human behaviour in a structured manner. Future work could focus on transferring knowledge from CE and designing robot control strategies for HRC safety.
