Design and analysis of active fluid-and-cellular solid composites for controllable stiffness robotic elements
… with active fluids-were be designed to have controllable stiffness to take the form of a continuous body of a soft robot. This represents an improvement compared to past efforts in soft robotics, which often involved modifying the infrastructure of current, rigid robots to yield softer ones. …

Analytical and Numerical Approaches on the Stiffness of Magnetorheological Fluid Filled Spring
… mechanical spring generally exhibits uniform stiffness. This thesis studies a mechanical spring filled with magnetorheological (MR) fluid to achieve controllable stiffness. The hollow spring filled with MR fluid is subjected to a controlled magnetic field in order to change the viscosity of …

Wearable exoskeleton systems based-on pneumatic soft actuators and controlled by parallel processing
… fingers) problem for post-stroke patients, a new controllable stiffness bending actuator has been developed with a novel prototype. To control this new rehabilitation exoskeleton, online and offline controller systems have been designed for the hand exoskeleton and the results have been assessed …

Design and Development of a Minimally Invasive Endoscope: Highly Flexible Stem with Large Deflection and Stiffenable Exoskeleton Structure
… cameras, and biopsy tools on the distal end. The stiffness required to support these tools makes it difficult for the scopes to navigate the twisted path of the colon without damaging the inside wall of the colon or distorting its shape. In addition, little is known about how sharp and forceful …

A Novel Fiber Jamming Theory and Experimental Verification
<p>This thesis developed a novel theory of fiber jamming and experimentally verified it. The theory relates the performance, which is the ratio between the stiff and soft states of a fiber jamming chamber, to three relative design parameters: the ratio of the wall thickness to the membrane inner …
