Coupling between the Output Force and Stiffness in Different Variable Stiffness Actuators
Actuators, 2014 The fundamental objective in developing variable stiffness actuators is to enable the actuator to deliberately tune its stiffness. This is done through controlling the energy flow extracted from internal power units, i.e., the motors of a variable ...
