Exploring the Limits of a Redundant Actuation System Through Co-Design
IEEE Access, 2021 This paper assesses the energy efficiency of a redundant actuation architecture combining Quasi-Direct Drive (QDD) motors and Series Elastic Actuators (SEAs) by comparing its energy consumption to Geared Motors (GMs) and SEAs alone.

Artificial Knee Joints Actuators with Energy Recovery Capabilities: A Comparison of Performance
Journal of Robotics, 2016 The human knee absorbs more energy than it expends in level ground walking. For this reason it would be useful if the actuation system of a wearable robot for lower limbs was able to recover energy thus improving portability.

Effects of discretization on the K-width of series elastic actuators [PDF]
2017 IEEE International Conference on Robotics and Automation (ICRA), 2017 Rigid haptic devices enable humans to physically interact with virtual environments, and the range of impedances that can be safely rendered using these rigid devices is quantified by the Z-Width metric. Series elastic actuators (SEAs) similarly modulate the impedance felt by the human operator when interacting with a robotic device, and, in particular,

Study on Compliant Actuator of the Knee Joint for Exoskeleton
Jixie chuandong, 2021 The compliance of the joint for exoskeleton is very important in adapting to the wearer's motions and human-machine compatibility. However，the conventional rigid or passive compliant mechanisms cannot achieve the purpose of active compliance due to the ...

Concept of a Series-Parallel Elastic Actuator for a Powered Transtibial Prosthesis
Actuators, 2013 The majority of the commercial transtibial prostheses are purely passive devices. They store energy in an elastic element during the beginning of a step and release it at the end.
