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,

Limit cycles and stiffness control with variable stiffness actuators
2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012Variable stiffness actuators realize highly dynamic systems, whose inherent mechanical compliance can be properly exploited to obtain a robust and energy-efficient behavior. The paper presents a control strategy for variable stiffness actuators with the primarily goal of tracking a limit cycle trajectory and a desired stiffness, which is a function of ...

Drum stroke variation using Variable Stiffness Actuators
2014 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2014One interesting field of robotics technology is related to the entertainment industry. Performing a musical piece using a robot is a difficult task because music presents many features like melody, rhythm, tone, harmony and so on. Addressing these tasks with a robot is not trivial to implement.

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 ...
