Energy-Efficient Variable Stiffness Actuators
IEEE Transactions on Robotics, 2011 Variable stiffness actuators are a particular class of actuators that is characterized by the property that the apparent output stiffness can be changed independent of the output position. To achieve this, variable stiffness actuators consist of a number of elastic elements and a number of actuated degrees of freedom, which determine how the elastic ...

Embodying Desired Behavior in Variable Stiffness Actuators* [PDF]
IFAC Proceedings Volumes, 2011 Variable stiffness actuators are a class of actuators with the capability of changing their apparent output stiffness independently from the actuator output position. This is achieved by introducing internally a number of compliant elements, and internal actuated degrees of freedom that determine how these compliant elements are perceived at the ...
