Variable Stiff Revolute Joint for Compliant Robot
Volume 6: Design, Systems, and Complexity, 2021Abstract Over the past decades industrial robot manipulators have expanded throughout the automation landscape with their high degree of repeatability and accuracy. For safety reasons these robots are not allowed to share their workspace along with humans, which limits the various tasks that can be performed by a human-robot ...

A new variable stiffness robot joint
Industrial Robot: An International Journal, 2015Purpose – This study aims to propose a new variable stiffness robot joint (VSR-joint) for operating safely. More and more variable stiffness actuators are being designed and implemented because of their ability to minimize large forces due to shocks, to safely interact with the user and their ability to store and release

Stiffness control of variable stiffness joint using electromyography signals
2013 IEEE International Conference on Robotics and Automation, 2013We have developed a multi-functional joint mechanism with variable joint stiffness and the ability to sense external forces. In this joint, silicone rubber cushions are employed to adjust the joint stiffness by controlling the pressure in the cushions.

A Novel Underactuated Robotic Finger with Variable Stiffness Joints
2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019Existing robotic hands mostly consist of rigid finger mechanism with constant joint stiffness, leading to poor handling performance and even unexpected safety issues. This paper proposed a novel underactuated robotic finger with variable stiffness joints based on human finger anatomy and electrostatic adhesion(ESA) principle.
