Exoscarne: Assistive Strategies for an Industrial Meat Cutting System Based on Physical Human-Robot Interaction
Abstract
Musculoskeletal disorders of the wrist are common in the meat industry. A proof of conceptof a physical human-robot interaction (pHRI)-based assistive strategy for an industrial meat cuttingsystem is demonstrated which can be transferred to an exoskeleton later. We discuss how a robot canassist a human in pHRI, specifically in the context of an industrial project i.e for the meat cuttingindustry. We developed an impedance control-based system that enables a KUKA LWR robot toprovide assistive forces to a professional butcher while simultaneously allowing motion of the knife(tool) in all degrees of freedom. We developed two assistive strategies — a force amplification strategyand an intent prediction strategy - and integrated them into an impedance controller
