Digital twin model based on human data and human factors, model generation using musculoskeletal dynamics algorithm, real-time usage data-based reinforcement learning human model update. It possesses source technology that can extend usage time and consider worker safety in emergency situations with hybrid robot drive technology (series elastic drive technology). It is manufactured in an exoskeleton form that operates through human-robot interaction, in a way that attaches to the outside of the human body to support or assist human strength.
