This research introduces a low-power, light-weight wearable powered waist exoskeleton with mechanical clutch. By processing the signals from multiple sensors, the human movement intention can be precisely identified and estimated. The exoskeleton can help reduce the work done by human muscle and has a loading capacity up to 20kg. Through the mechanical clutches applied, the exoskeleton can lock the...
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,...
This paper describes a 2 DOF (Degrees of Freedom) massaging robot prototype: Massagebot, which is equipped with two kinds of massage structure and can realize two kinds of massage by scratching and shaking on user's back. Massagebot has two-wheel gripper, and two-triangular structure of body with good stability. In terms of path planning, we proposed a location algorithm based on simplified acupuncture...
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,...
The operational difficulty of Transcranial Doppler (TCD) limits its use in normal clinical settings. We therefore present a robotic arm consists of five degrees of freedom which are achieved by four motors and one extra flexible spring, to assure appropriate pressure on temporal window. With proper control strategies, the robotic arm can move the TCD probe to automatically search temporal window positions...
