In this paper, we design a novel knee exoskeleton. The designed exoskeleton has a 1 DOF with knee joint actuated in the sagittal plane. The exoskeleton is actuated base on Series Elastic Actuator (SEA) instead of traditonal stiff actuator. SEA is a compliant actuator, having the advantages of low output impedance, low friction, high quality force control and backdrivability. Thanks to these nice characteristics,...
In order to help spinal cord injury (SCI) patients to walk again, a medical robot exoskeleton have been developed to assist these patients to walk independently in SIAT, Shenzhen. The research of this article is exoskeleton robot single joint load adaptive servo control. Considering the volunteers, wearing an exoskeleton robot, joints have significant changes in load torque and the moment of inertia,...
This paper presents a novel device that can be attached to a lower-limb exoskeleton to assist lower extremity hemiplegic patients during sitting down and standing up. Such device serves as a self-adaptive exoskeleton chair. The mechanical design has simple structure, great applicability, reliability and high driving efficiency. This paper first models and analysis the muscle forces during standing...
