The French Unit of the M-NEST Learning Factory is provided by Arts et Metiers Institute of Technology. The PeTRiiV platform developed by the Chalon-sur-Saône institute is an eXtended Reality environment aimed to virtual engineering in the context of Industry 4.0. It gathers state-of-the-art immersive systems, driving simulators, several VR/AR display and interaction devices and software development. It is used for research projects, industrial applications and teaching activities, to answer the challenges of Industry 4.0 on digital/virtual twins, collaborative design, manufacturing and maintenance, professional training and education of new talents. The added-value manufacturing platform Vulcain developed on the Metz Campus offers robotized industrial-size press cell for metal forming and a multi-process robotized cell for robot-assisted welding, additive manufacturing, grinding, incremental forming… These pedagogical platforms are the backbone of the developed learning and teaching factories in the M-NEST project.
