Due to the rising demand in efficiency and sustainability in commercial aviation, aircraft manufacturers increase the usage of high performance, lightweight materials like carbon fiber reinforced plastics (CFRP). These materials pose new challenges to manufacturing processes concerning cost-effectiveness and quality requirements. To meet these challenges the Institute of Structures and Design within the German Aerospace Center (DLR) designed a flexible robotic manufacturing cell at the Center for Lightweight Production Technology (ZLP) in Augsburg. The multifunctional cell (MFZ) can integrate processes for production and inspection on an industrial scale. Due to large workpieces like fuselage components or wing skins and low production quantities, workshop space, and investment cost are major concerns for effective CFRP production. The large size of the cell (30×15×7 m) demands a highly reconfigurable space. The platform is composed of five ceiling mounted robots on a gantry like machine frame and may be divided in smaller independent cells. The multifunctional cell will improve the understanding of requirements of future production processes for lightweight components by providing a highly flexible platform on an industrial scale. The cell itself is prepared to perform different processes by having a large workspace with multiple manipulators, a high accessibility for material logistics and state of the art communication technology. Additionally a sensor guided system is developed to improve robot accuracy to satisfy the high quality requirements in aerospace industries. The change from manual manufacture to automatic production for CFRP components will not be instantaneous, because new processes need to be validated and many process steps contain many complex manipulation tasks that are very hard to automate. This is why a gradual change is more probable to happen. In this case different tools and jigs need to be easily accessible by humans to perform non-automated tasks. Additionally direct human machine interaction could also play a major role, as the individual advantages of machines and human workers can be used. Humans distinguish themselves in perception and improvisation but lack in strength, speed, and repeatability. In contrast robots excel in these categories but are not able to react to unforeseen changes.
