TL;DR
The study investigates how a cobot's production rhythm influences experiential locus of control (ELoC) and emotional state during collaborative assembly. Using a within-subjects design with three pacing conditions and measures including ICI, NARS, ELoC, and the Self-Assessment Manikin, the authors find no overall effect of rhythm on ELoC or emotion, but observe rhythm-related differences in performance and condition preferences, along with nuanced correlations that depend on rhythm. Reliability concerns with the ICI scale and modest sample size temper some conclusions, suggesting that personal psychological characteristics modulate human-cobot interaction and should inform customization in Industry 5.0 settings. The findings highlight the importance of tailoring cobot pacing to individual traits to optimize well-being and productivity in industrial HRI contexts.
Abstract
In industrial scenarios, there is widespread use of collaborative robots (cobots), and growing interest is directed at evaluating and measuring the impact of some characteristics of the cobot on the human factor. In the present pilot study, the effect that the production rhythm (C1 - Slow, C2 - Fast, C3 - Adapted to the participant's pace) of a cobot has on the Experiential Locus of Control (ELoC) and the emotional state of 31 participants has been examined. The operators' performance, the degree of basic internal Locus of Control, and the attitude towards the robots were also considered. No difference was found regarding the emotional state and the ELoC in the three conditions, but considering the other psychological variables, a more complex situation emerges. Overall, results seem to indicate a need to consider the person's psychological characteristics to offer a differentiated and optimal interaction experience.
