A compact variable stiffness joint for compliant robotics enabled by torsion-spring mean-diameter variation

Abstract For robotic applications requiring compliance and safety in rehabilitation training, physical human–robot collaboration, and unstructured environments, this study proposes a variable-stiffness joint design method, termed TSDV, based on the mean-coil-diameter variation mechanism of a torsion...
