OCCUPATIONAL APPLICATIONSIn recent years, various upper limb exoskeletons have been developed aiming to support industrial workers for a range of tasks and reduce risks work-related musculoskeletal disorders. Most commercially available are passive systems that use compliant elements such as springs or elastic components store release energy assist the user’s motion. In contrast, many active exoskeletons, which typically comprised one more powered actuators provide joint assistance, still in research development stages. Nevertheless, functions efficacy exoskeleton need be further compared assessed. This study presents model-based approach evaluate different designs assistance demonstrates benefits both methods an overhead lifting task. addition, modeling simulation indicate potential advantages using based on electromyography.
