...Sri Sadhan Jujjavarapu; Hemanth Manjunatha; Ehsan Tarkesh Esfahani Variable stiffness end-of-arm actuators can add dynamic manipulation capabilities to stiff manipulators and simultaneously enhance safety. The presence of an elastic element in these actuators can be used for absorbing impact energy...

... of stiffness [ 3 , 4 ]. Moreover, the feature of free deformation in any direction enables their shape control to need multiple actuators that increase the cost and size of the system. These limitations could be addressed by providing the structures with variable stiffness that can transition between soft...

... introducing mechanical compliance to robotic systems. While extensive studies explore variable stiffness joints/actuators, variable stiffness links for safe physical human–robot interactions are much less studied. This article details the design and modeling of a compliant robotic arm whose stiffness can...

...Jue Yu; Yong Zhao; Genliang Chen; Yeqing Gu; Chao Wang; Shunzhou Huang This paper puts forward a linear variable stiffness joint (VSJ) based on the electromagnetic principle. The VSJ is constituted by an annular permanent magnet (PM) and coaxial cylindrical coil. The output force and stiffness...
