The flexprass experiment shall prove feasibility of combining lightweight desktop robots capable of close human-machine collaboration (Schunk) with high-precision manipulators (Fraunhofer IPT), e.g., needed for automated assembly of optical systems and lasers. Partners configured customized manipulator based on PowerCube modules according to industry-relevant assembly scenarios defined for the experiment such as the alignment of fast axis collimation lenses (FAC), setup peripheral hardware and worked out control concept.
