This UC will tackle the challenges in robot-automated assembly, including the complexity of the assembly process and the need for skilled workers. XR5.0’s AI and XAI solutions will detect and recognise the influence that different product variants have on the plant, providing direct information via the XR environment to employees on which parts of the complex systems are relevant and uncritical. To this direction, generative AI technology will be employed to produce product variants and their cyber-representations for visualisation in the XR space. Moreover, virtual commissioning and augmented reality technology will be utilised to improve the efficiency and productivity of the assembly process, concluding to mitigate the shortage of skilled workers, reduce the consumption of test parts and waste, and provide a more sustainable approach to operations.
