IROS 2020 Workshop: Compliant Actuation for Human Performance Augmentation

Nov. 23, 2020—One way to imagine human augmentation is to consider an energetically active robot that supplements muscle power with external energy. Another way to imagine human augmentation is to consider solely human-powered energetically passive devices; two examples are bicycles and ice-skates. In this talk, I will discuss the hidden potential of an emerging human-powered compliant actuation...

Our paper “Variable Stiffness Springs for Energy Storage Applications” is published in IEEE ICRA 2020

Aug. 31, 2020—Authors: Sung Y. (Joel) Kim, Tiange Zhang, and David J. Braun Abstract: Theory suggests an inverse relation between the stiffness and the energy storage capacity for linear helical springs: reducing the active length of the spring by 50% increases its stiffness by 100%, but reduces its energy storage capacity by 50%. State-of-the-art variable stiffness actuators used...
