Tendon-Driven Jamming Mechanism for Configurable Variable Stiffness
Soft Robotics, 2021Stiffness transition of a soft continuum body is an essential feature for dexterous interaction with an unstructured environment. Softness ensures safe interaction, whereas rigidness generates high force for movement or manipulation. Vacuum-based granular jamming is a widely used technique for on-line stiffness transition because of its high ...

Variable Stiffness Mechanisms Using Spherical Continuously Variable Transmissions
Volume 4A: Dynamics, Vibration, and Control, 2015Some robot developers are considering elasticity to provide compliance for better adaption to a changing environment, shock resistance and safer human-robotic interactions (HRI). In this study we simulate a spherical continuously variable transmission (CVT) to validate its ability as the primary mechanism in a variable stiffness device for a 1D robotic

A New Variable Stiffness Suspension Mechanism
Volume 6: 35th Mechanisms and Robotics Conference, Parts A and B, 2011A new variable stiffness suspension system based on a recent variable stiffness mechanism is proposed. The overall system is composed of the traditional passive suspension system augmented with a variable stiffness mechanism. The main idea is to improve suspension performance by varying stiffness in response to road disturbance.
