The SMART project is an innovative endeavor that is developing a complex system consisting of five main components. The first component is an AI-supported digital recognition system that records the posture of the employees and the progress of the assembly steps in real time. This data serves as the basis for intelligent control of the assembly process and route planning for the robot. The second component being developed is software for modeling the work steps, documentation and communication with remote experts. An augmented reality (AR) visualization is integrated as the third component in order to efficiently communicate important information and instructions to employees. The fourth component involves the application of robot route planning in the employees’ work area. Finally, as the fifth and last component, a digital twin of the real work environment is created to provide a simulation-based platform for the integration of the subsystems and the implementation of the developed algorithms. This overall system promotes the interaction between the real work environment and its digital counterpart.
