Design of parallel variable stiffness actuators

CW Mathews, DJ Braun - IEEE Transactions on Robotics, 2022 - ieeexplore.ieee.org
Direct-drive motors (DDMs) have been increasingly used for robot actuation because they
provide high-fidelity torque control, but they typically have low torque density. Gearing can …
