Presented in this paper are two cases from a heavy vehicle manufacturer which demonstrate the potential width of Human-Industrial Robot Collaboration workstations. Case I simulates in machining environments, the assisted inspection of inline engine blocks and Case II simulates in logistics environments, the assisted material preparation for assembly line orders. The analysis and simulations were carried out with a software tool that combined digital human modelling, robotic simulation, path planning and use of technical computing tools. Results demonstrate the improvement of process ergonomics and cycle time.
