  This paper introduces two case studies combining the field of industrial
robotics with Mixed Reality (MR). The goal of those case studies is to get a
better understanding of how MR can be useful and what are the limitations. The
first case study describes an approach to visualize the digital twin of a robot
arm. The second case study aims at facilitating the commissioning of industrial
robots. Furthermore, this paper reports the experiences gained by implementing
those two scenarios and discusses the limitations.
