In the field of individual and small series production, many assembly steps are performed manually. Therefore, the assembly worker must be very flexible. To ensure the quality of his work, he needs systematic work instructions and quality assurance. The Plant@Hand tool cart combines technologies for needs-oriented visual information support with artificial intelligence measures in a compact tool cart. Augmented reality technology helps him to deepen and firmly establish his process understanding of workflows. With the help of a tablet or AR glasses, such as Microsoft HoloLens, the assembly worker is provided with additional (advanced) information on components, work steps, and checklists directly in his line of sight. Moreover, 3D animations guide him step by step through his work and inform him of the next steps.
