Abstract
In this study, we developed a passive type lower limb muscle strength assisting exoskeleton robot capable of static and dynamic muscle strength support to prevent injuries in industrial fields such as construction. While conventional exoskeleton robots mainly provide static muscle assistance, this exoskeleton robot does not provide only static assistance for seated situation, but also provides dynamic assistance for standing motion. Lockable gas springs are applied to support muscle power and appropriate analysis was performed. When the user is seated, the force acting on the thigh support is calculated, and the optimal cross-sectional area and thickness are selected through structural analysis. As a result using electromyography tests, when wearing the exoskeleton robot, it was confirmed that the magnitude of the force consumed by the muscle was reduced significantly.
