Fiat Chrysler Automobiles (FCA) is the world’s seventh biggest automotive enterprise with a global reach of operations. Despite the novelty of IoT and AR solutions on the Polish market, FCA decided to invest in development of these solutions with the help of the best industrial software experts from Transition Technologies. It was just through the first couple of meetings that the scope of the research project was set up along… with a plan to implement the elements of its results. The resulting solution created a safe and efficient working environment in the manufacturing plant thanks to scalability corresponding to multiple various positions and jobs. The project itself has been named LINEA I. The implementation of the Industry 4.0 concept has begun through support of an MRO department by implementing an IoT-based solution with a corresponding Augmented Reality toolkit for its workers.
