Abstract: By working side-by-side with humans in a production environment, collaborative robots (cobots) can be helpful and versatile and can efficiently support activities in modern factories. A review of the extant literature identified an opportunity to build user-friendly human-robot interfaces and confirmed the need to enhance the perceptions of human safety conditions and requirements during interactions with cobots when performing manufacturing tasks. Therefore, this study seeks to deepen the knowledge regarding the use of cobots, based on introducing novel safety system architecture for human-robot collaboration in a shared workspace. The degree of collaboration is investigated, focusing on the safety requirements when human operators perform tasks involving cooperation between humans and cobots in a combined workstation. As a result, this study extends the previous literature by proposing a conceptual safety system architecture that is especially useful for covering safety requirements during the design stage of a collaborative workstation so as to minimise safety risks to humans, resulting in a dynamic safety framework that allows for the use of advanced robotics in an Industry 4.0 environment.
