The number of patients with knee impairments caused by a stroke, spinal cord injury, post-
polio, injury, osteoarthritis, or other related diseases is increasing worldwide. Robotic …

The increasing necessity of load-carrying activities has led to greater human
musculoskeletal damage and an increased metabolic cost. With the rise of exoskeleton …

This article presents a novel reconfigurable torque-controllable variable stiffness actuator
(RVSA) for knee exoskeleton. The concept of reconfiguring the pulley block is proposed to …

This letter presents design and control innovations of wearable robots that tackle two
barriers to widespread adoption of powered exoskeletons: restriction of human movement …

Robotic exoskeleton assistance is an effective method for the treatment of patients with
movement disorders. First, this article presents a variable stiffness knee exoskeleton robot …

In this paper, the mechanical design of a novel variable stiffness mechanism (VSM) with
reconfigurability is presented. The design of VSM is based on a zero-length base link four …

In this paper, a novel revolute joint of variable stiffness with reconfigurability (JVSR) is
presented. The JVSR is designed with a compliant joint mechanism, and is able to vary …

This paper investigates the energy performance of human load carriage with a variable
damped suspended backpack. A vertical double-mass coupled-oscillator model is adopted …

This paper presents a novel variable stiffness actuator (VSA) based on a cam-leaf spring
mechanism, namely, CLSM-VSA. A sophisticatedly designed cam is used to regulate the …

Despite the increasing interest in using powered ankle-foot orthoses for assistive purposes,
their development and benchmarking still present core challenges. Powered orthoses have …
