A variable-stiffness and healable pneumatic actuator

Materials Horizons, 2023
A 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.

Towards a robust variable stiffness actuator

2013 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2013
Robots 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, 2012
Variable 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, 2014
One 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

2021
Based 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 ...

Torque Estimation in Variable Stiffness Actuators

2016 International Conference on Systems Informatics, Modelling and Simulation (SIMS), 2016
For the use in rehabilitation robotic devices, various types of actuators are currently being investigated. Variable impedance actuators seem promising concerning individualized training, comfort and safety. For the control of actuators, some sensors are required, however, to keep the rehabilitation device light, also the implementation of measuring ...
