This thesis deals with the design of small-scale experimental tests for the ergonomic analysis of upper limb exoskeletons in automotive assembly workstations. The study was carried out at the Stellantis plant in Mirafiori, Turin, in collaboration with Homberger SpA and SuitX by Ottobock. The device used for the experimental tests was Ottobock's IX Shoulder Air, designed to support the upper limbs during overhead tasks. The study began with research into the needs that led to the introduction of exoskeletons, a general overview of the current characteristics of exoskeletons on the market, and a general description of the regulatory landscape in use.
