Energy-Efficient Variable Stiffness Actuators [PDF]
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 ...

Variable Stiffness Actuators: A Port-Based Power-Flow Analysis [PDF]
IEEE Transactions on Robotics, 2012 Variable stiffness actuators realize a novel class of actuators, which are capable of changing the apparent output stiffness independently of the output position. This is mechanically achieved by the internal introduction of a number of elastic elements and a number of actuated degrees of freedom (DOFs), which determine how the elastic elements are ...

Variable Stiffness Actuators: The User’s Point of View [PDF]
International Journal of Robotics Research, 2015 Since their introduction in the early years of this century, variable stiffness actuators (VSA) witnessed a sustained growth of interest in the research community, as shown by the growing number of publications. While many consider VSA very interesting for applications, one of the factors hindering their further diffusion is the relatively new ...

A variable-stiffness and healable pneumatic actuator
Materials Horizons, 2023A pneumatic actuator based on variable-stiffness and self-healing polymers shows high load capacity at room temperature but can be actuated pneumatically upon heating. And it can be thermally healed after damaging, thus can prolong its service time.

Variable Stiffness Actuator Structure for Robot
2021Based on the idea of regulating the variation on stiffness by controlling the number of springs involved in the work, this paper designs a kind of variable stiffness actuator (VSA) which can be applied to the field of robot. The variable stiffness structure takes the spiral tensile spring as the elastic element, and the number of springs Participating ...

Towards a robust variable stiffness actuator
2013 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2013Robots with Variable Stiffness Actuators (VSA) are intrinsically flexible in the joints. The built-in mechanical spring not only has the advantage of a higher peak performance, but also leads to a more robust robot. This paper presents and analyzes the threats to a VSA equipped robot that arise from external or internal origin. Influences of mechanical,

Towards Variable Stiffness Control of Antagonistic Twisted String Actuators
, 2014 This paper shows the possibility of using two antagonistic twisted strings actuators as a new type of variable stiffness actuator. Variable stiffness model of the twisted string actuator is identified empirically, and the control strategy is proposed for
