Low-cost variable stiffness joint design using translational variable radius pulleys
Mechanism and Machine Theory, 2018 Robot joints are expected to be safe, compliant, compact, simple and low-cost. Gravity compensation, zero backlash, energy efficiency and stiffness adjustability are some desired features in the robotic joints. The variable radius pulleys (VRPs) provide a simple, compact and low-cost solution to the stiffness adjustment problem. VRP mechanisms maintain

Robust estimation of variable stiffness in flexible joints [PDF]
2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011 We consider the problem of estimating on line the nonlinear stiffness of flexible transmissions in robot joints, with special reference to actuation devices with adjustable stiffness in serial configuration. These joints are characterized by a principal motor for controlling the link motion and secondary motor for adjusting the stiffness.

A Variable Stiffness Elbow Joint for Upper Limb Prosthesis [PDF]
2019 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2019 One of the main research trends toward next-generation prostheses and bionic aids is to better replicate human motor behaviours and to improve the interconnection with the human sensory-motor architecture. One of the natural characteristics of the human arm of utmost importance in our interaction with the environment is our ability to vary the ...
