A Portable Upper-Limb Exoskeleton With Pneumatic-Driven Variable-Stiffness Units for Long-Term Working in Fixed Overhead and Ahead Postures

RA-L 2025

Long-term working in fixed postures often leads to muscle fatigue and musculoskeletal disorders. Existing passive exoskeletons for overhead tasks introduce resistance during arm lowering, while active exoskeletons face limitations due to their weight and lack of comfort. To address these challenges,

A Variable-stiffness Neck Exoskeleton with Pneumatic-driven Actuators for Prolonged Head Flexion Assistance

IROS 2025

Surgeons are frequently subjected to prolonged unnatural postures, such as sustained neck flexion during surgical procedures, increasing their susceptibility to work-related musculoskeletal disorders (WMSDs). Despite the prevalence of such issues, there remains a scarcity of ergonomic solutions that

A Novel Jamming Structure With Interlocking Mechanism Towards Applications in Wearable Robots

RA-L 2022

The adoption of variable stiffness actuators allows robots to take advantages of both rigid and soft structures. Jamming based variable stiffness structures are receiving increased attentions due to advantages of light weight, easy fabrication, and so on. However, the maximum bending stiffness and s
