Design and Experiment of an Anthropomorphic Robot Hand for Variable Grasping Stiffness
IEEE Access, 2021 This paper introduces an anthropomorphic robot hand that has variable grasping stiffness to unknown objects without damage. The robot hand has four fingers, 13 DoFs (Degrees of Freedom) with three SEA (Series Elastic Actuator) modules in the index ...

Photon pressure induced test mass deformation in gravitational-wave detectors [PDF]
, 2007 A widely used assumption within the gravitational-wave community has so far been that a test mass acts like a rigid body for frequencies in the detection band, i.e. for frequencies far below the first internal resonance.

Robust Force Control of Series Elastic Actuators [PDF]
Actuators, 2014 Force-controlled series elastic actuators (SEA) are widely used in novel human-robot interaction (HRI) applications, such as assistive and rehabilitation robotics. These systems are characterized by the presence of the “human in the loop”, so that control response and stability depend on uncertain human dynamics, including reflexes and voluntary forces.

Bi-directional series-parallel elastic actuator and overlap of the actuation layers [PDF]
Bioinspiration & Biomimetics, 2016 Several robotics applications require high torque-to-weight ratio and energy efficient actuators. Progress in that direction was made by introducing compliant elements into the actuation. A large variety of actuators were developed such as series elastic actuators (SEAs), variable stiffness actuators and parallel elastic actuators (PEAs).

The Energy Amplification Characteristic Research of a Multimodal Actuator
International Journal of Advanced Robotic Systems, 2016 A multimodal actuator is proposed to fulfil the different walking patterns of a power-assisted knee exoskeleton. With this actuator, the exoskeleton leg can realize several modes of operation, including series elastic actuation, stiff position control ...
