Which repercussions of the introduction of a cobot on productivity and biomechanical constraints on operators in a collaborative task?

Résumé

This paper evaluates the repercussions of the introduction of a cobot in a collaborative motor task. Two studies were performed: first to compare a task in collaboration with a cobot or a human and second to analyse the impact of pace (i.e., speed and leader), both on productivity, quality of interactions, operator's posture and attentional demand. Thirty-four participants in the first study (S1) and twenty in the second study (S2), were equipped with motion capture sensors. They performed a collaborative motor task with a YuMi cobot and with another human in S1, and performed the same task with the cobot at different imposed pace and at free pace in S2. Productivity, quality of the interactions, participant's posture and attentional demand were measured in both studies. As main results, productivity seemed to be less important with the cobot than with a human, with less interactions between operator and cobot. Moreover, attentional demand was higher with the cobot coworker, but also with high paces. Posture was less awkward, so less risky for the health, with the cobot co-worker, but the pace seemed to not influence it. Leading or following the pace seemed to not influence these variables. Actually, the differences between humanhuman and human-cobot interactions were mainly due to the slowest pace due to the cobot, except for the better posture which could be linked with the introduction of the cobot.
