Actuation selection for assistive exoskeletons: matching capabilities to task requirements
Andrea Calanca, Stefano Toxiri, Davide Costanzi, Enrico Sartori, Rudy Vicario, Tommaso Poliero, Christian Di Natali, Darwin G. Caldwell, Paolo Fiorini, Jesus Ortiz
Selecting actuators for assistive exoskeletons involves decisions in which designers usually face contrasting requirements. While certain choices may depend on the application context or design philosophy, it is generally desirable to avoid oversizing actuators in order to obtain more lightweight and transparent systems, ultimately promoting the adoption of a given device...

Enhancing Mobility With Quasi-Passive Variable Stiffness Exoskeletons
Shoes were invented to provide user comfort using rubber soles, despite marginal improvement in human mobility. Unlike shoes, current lower-limb exoskeletons use fixed stiffness springs to store and recycle energy to improve mobility. However, the maximum kinetic energy a human...

Reducing the Energy Cost of Human Running Using an Unpowered Exoskeleton
In this paper, we present a new perspective to design an unpowered exoskeleton for metabolic rate reduction in running. According to our studies on human biomechanics, it was observed that having a torsional spring which applies torque as a linear...

A Soft Exosuit for Flexible Upper-Extremity Rehabilitation
Steven Lessard, Pattawong Pansodtee, Ash Robbins, James M. Trombadore, Sri Kurniawan, Mircea Teodorescu
For stroke survivors and many other people with upper-extremity impairment, daily life can be difficult without properly functioning arms. Some modern physical therapy exercises focus on rehabilitating people with these troubles by correcting patients’ perceptions of their own body to...

Abstract
Powered exoskeletons can empower paraplegics to stand and walk. Actively controlled hip ab/adduction (HAA) is needed for weight shift and for lateral foot placement to support dynamic balance control and to counteract disturbances...
