Design of an Elastic Actuation System for a Gait-Assistive Active Orthosis for Incomplete Spinal Cord Injured Subjects [PDF]
, 2016 A spinal cord injury severely reduces the quality of life of affected people. Following the injury, limitations of the ability to move may occur due to the disruption of the motor and sensory functions of the nervous system depending on the severity of

Iterative Machine Learning for Precision Trajectory Tracking with Series Elastic Actuators
, 2017 When robots operate in unknown environments small errors in postions can lead to large variations in the contact forces, especially with typical high-impedance designs. This can potentially damage the surroundings and/or the robot.

Calibration Uncertainty for Advanced LIGO's First and Second Observing Runs [PDF]
, 2017 Calibration of the Advanced LIGO detectors is the quantification of the detectors' response to gravitational waves. Gravitational waves incident on the detectors cause phase shifts in the interferometer laser light which are read out as intensity ...

Design and optimal springs stiffness estimation of a Modular OmniCrawler in-pipe climbing Robot
, 2017 This paper discusses the design of a novel compliant in-pipe climbing modular robot for small diameter pipes. The robot consists of a kinematic chain of 3 OmniCrawler modules with a link connected in between 2 adjacent modules via compliant joints. While

2011 IEEE International Conference on Rehabilitation Robotics, 2011 Robotics used for diagnostic measurements on, e.g. stroke survivors, require actuators that are both stiff and compliant. Stiffness is required for identification purposes, and compliance to compensate for the robots dynamics, so that the subject can move freely while using the robot.

Series Elastic Actuators for Small-Scale Robotic Applications [PDF]
Journal of Mechanisms and Robotics, 2017 Torque control of small-scale robotic devices such as hand exoskeletons is challenging due to the unavailability of miniature and compact bidirectional torque actuators. In this work, we present a miniature Bowden-cable-based series elastic actuator (SEA) using helical torsion springs.

From Series Elastic Actuation to Series-Parallel Elastic Actuation
, 2014 Actuators are key components for moving and con- trolling a mechanism or system. However, the torque to weight ratio and the energy efficiency of the current state of the art actuators is much lower than in human muscles. As a consequence, among others, manipula- tors for human robot interaction in industry or service applications have a low payload to
