From Cooperation to Collaboration: A Game-Changing Use of Cobots in Circular Manufacturing Toward Industry 5.0?
摘要
As circular manufacturing systems develop to reprocess second-hand products, manufacturers face obstacles in recovering a large variety of products fluctuating in quality and requiring an extensive workforce. That prompts researchers to explore cobotics in cooperative scenarios, automating some tasks while humans handle others. The existing research highlights increased productivity and reduced physical load when using cobots. However, in current literature, experiments are not confronted with operators’ feedback and concepts from human and social sciences as the meaning of work or cognitive load are ignored. In particular, research in the Human and Social Sciences shows that cooperative approaches often fragment tasks, diminishing workers’ skills and professional identity. This article aims to challenge these findings through a multidisciplinary study in industrial engineering, ergonomics, and occupational psychology, providing empirical evidence from an experiment with 50 participants. This article stands out by proposing a human-centered collaborative scenario, where humans control the process with cobot assistance from an Industry 5.0 perspective. Intending to provide scientific proof to surpass technological promises, the experimental approach is relatively little used in engineering in the field of technologies for circularity, despite its strong complementarity with the results of the literature. The article also stands out for its inclusion of several little-studied, albeit crucial, dimensions, such as learning, meaning at work, and physical and cognitive aspects based on multidisciplinary expertise. Results show that cobots used collaboratively, enhance participants’ training, do not negatively impact operational performance, and preserve physical health without affecting cognitive load or work meaning.
