Effects of pace on productivity and physical and mental workloads in a Human-Cobot Collaboration

Résumé

Introduction: Musculoskeletal disorders (MSDs) represent a prevalent global occupational health concern, primarily associated with high biomechanical solicitations, mental workload, and work pace. Although cobots have shown promise in reducing risks of MSDs, a question of interest still persists as to how the effect of pace in hybrid human-machine collaboration will affect the operator, in terms of both physical and cognitive health and the production.

Methods: This study aimed to analyse the impact of pace on productivity, operators' posture and mental workload in a human-cobot collaboration.

Involving twenty participants engaged in a collaborative task with a cobot under three cobot-led paces, the study assessed productivity RULA scores (posture), dual task performance (cognitive resources) and NASA-TLX (workload).

Results: The findings revealed that an excessively high pace had counterproductive effects, leading to reduced efficiency and increased susceptibility to MSDs, both in terms of physical and mental workloads.

Conclusion: Therefore, in the context of a human-cobot collaboration, it is imperative to adapt the pace to operators' abilities in order to ensure optimal productivity while preserving their health, emphasizing the need for a balanced approach to pace management in such collaborative work scenarios.
