In the project AGREED, the DLR Center for Lightweight Production Technology, together with Premium Aerotec and other partners, conducted research into the development of sustainable assembly processes for metallic aircraft shells. The guiding theme was a significant increase in the degree of automation and digitalisation of the previously manual process steps. In its entirety, it addressed the vision of a flexible, partially autonomous and AI-controlled assembly with interchangeable participation of human workers and mobile CoBots as factory of the future according to Industry4.0 guidelines.
