Coordinated human-exoskeleton locomotion emerges from regulating virtual energy.
Published 2025-01-01“…Contribution: (1) In this paper, we experimented VER on a group of nine healthy individuals at different speeds (0.6m/s - 0.85m/s) to study the resultant gait coordination and naturalness on a large group of users. (2) The resultant assisted gait is compared to the natural and passive (zero-torque exoskeleton) walking conditions in terms of muscle activities, kinematic, spatiotemporal and kinetic measures, and questionnaires. (3) Moreover, we presented the VER's convergence proof considering the user contribution to the gait and introduced a metric to measure the user's contribution to gait. (4) We also compared VER performance with the phase-based path controller in terms of muscle effort reduction and joint kinematics using three able-bodied individuals. …”

Research and Application of the Hydraulic Connection Section in Nanmujiang River Fishway at Datengxia Water Conservancy Project
Published 2022-01-01“…As the only fish migration channel in the Nanmujiang River and the letdown path of ecological flow required by the downstream fish spawning sites,the Nanmujiang River fishway in Datengxia has complex operating conditions and large design flow variation.In addition,there is a water level difference between the technical fishway and the imitating natural fishway,which requires a hydraulic connection section to ensure a smooth transition of flow regimes and velocities.In order to ensure the effectiveness of the hydraulic connection section in the Nanmujiang River fishway,a variety of schemes based on previous project experience are proposed,and then the preliminary design scheme is determined by studying and comparing the schemes.Finally,the final design scheme is optimized and determined through physical model tests.According to the measured data of physical model tests,the optimized design scheme meets the requirements of fish in sailing upstream,and it has been applied in the construction of the Datengxia project and passed the completion test.At present,the scheme is in the trial operation stage.This paper proposes two different types of hydraulic connection section design schemes,which are respectively suitable for small and large flow rates and can provide references for similar fishway designs.…”
