Algorithmic Design of Low-Power Variable-Stiffness Mechanisms

open access: yesIEEE Transactions on Robotics, 2017
Compliant actuators enabling low power stiffness adaptation are missing ingredients and key enablers of next generation roboticsystems. One of the key components of these actuators is the mechanism implementing stiffness adaptation which requires sophisticated controland non-trivial mechanical design.
