Despite the increased interest in exoskeleton research in the last decades, not much
progress has been made on the successful reduction of user effort. In humans, biarticular …

Background Enabling persons with functional weaknesses to perform activities of daily living
(ADL) is one of the main challenges for the aging society. Powered orthoses, or …

Previous studies of robotic exoskeletons and prostheses with regenerative actuators have
focused on level-ground walking. Here we analyzed the lower-limb joint mechanical power …

This paper describes the design and development of an exoskeleton that can deliver
assistance-as-needed to patients or elderly with muscle weakness. Since the proof-of …

Background: Walking is a complex process that involves rhythmic movement of lower limb
along with the coordination of brain, nerves and muscles. If the coordination is disturbed …

Objective: Show the benefit of kinematically compatible joint structures in exoskeletons for
improving their performance in reducing metabolic consumption. Methods: Subjects were …

Robotic leg prostheses and exoskeletons can provide powered locomotor assistance to
older adults and/or persons with physical disabilities. However, limitations in automated …

Purpose: The assistive knee exoskeleton device is used for supporting the surrounding
ligaments, tendons, and muscles of the injured knee joint. Various knee exoskeletons have …

Although regenerative actuators can extend the operating durations of robotic lower-limb
exoskeletons and prostheses, these energy-efficient powertrains have been exclusively …

The task of a powered knee orthotic device (PKOD) is to assist the knee joint so that its
natural behavior can be restored. The key features of a PKOD that may help to regain such …
