On June 9, five different employees from the assembly and warehouse departments wore a passive exoskeleton during their shift and tested its mobility. During the activities, videos were recorded to record and evaluate the ergonomics of the employees using the leading characteristic method. To gather further movement data of the employees, the exoskeletons were equipped with a cell phone and corresponding holder, while the employees received two additional wristbands and a hip belt, each of which was equipped with additional acceleration sensors. The gathered data will serve as the basis for the development of an activity recognition system trained using machine learning methods. The employees showed a high willingness to wear the exoskeletons to relieve the body during exhausting activities and particularly approved of the excellent mobility of the skeletons.
