Practical design and implementation of an augmented reality based digital twin

This paper presents a practical example of design and implementation of an augmented reality based digital twin of moving wheeled robots in an indoor environment. The architecture developed is based on the RAMI (Reference Architectural Model Industry 4.0) framework and integrates both the physical and the digital twins, allowing continuous data exchange and real-time feedback loops between the two twins. From the physical twin perspective, the use of augmented reality (AR) headsets and position sensors enables to track the movement of the wheeled robots. The interest of the chosen architecture is a seamless communication of the decision and user interfacing elements including the AR headsets and the fulfilment layers of the digital twin. The current developed modules are deployed at a laboratory scale. The perspective of this work is an upscale to larger rooms and more industrial robots.
