On the proposal of a unified safety framework for industry 4.0 multi-robot scenario

Within the context of Industry 4.0, the presence of robotic systems inside the production plant is increasing, thus leading to the need for appropriate safety rules enhancing human-robot interaction. However, without a systematic approach, mapping all the possible scenarios becomes critical. This paper aims at laying the foundations for a unified safety-based semantic approach in cooperative multi-robot industrial environments. The objective of this study is to investigate an approach to organize, store and re-use construction safety knowledge by means of defining a new ontology and the construction of rules for safety application.
