A common issue with many commercial rehabilitative exoskeletons and orthoses are that
they can be prohibitively expensive for an average individual to afford without additional …

Lower-limb exoskeletons are external mechanical structures that support and assist human
users during locomotion. The earliest studies on exoskeletons date back to the 1960s …

This article presents the design and validation of a backdrivable powered knee orthosis for
partial assistance of lower-limb musculature, which aims to facilitate daily activities in …

Robot knee exoskeletons can not only help the rehabilitation training function of the elderly
and disabled patients, but also enhance the performance of healthy people in normal …

The practical long-term application of power-assisted exoskeleton robots requires
lightweight, high-efficient, and high-control precision actuators. Based on the improvement …

This paper presents the mechatronic design and initial validation of a partial-assist knee
orthosis for individuals with musculoskeletal disorders, eg, knee osteoarthritis and lower …

Wearable robots assist individuals with sensorimotor impairment in daily life, or support
industrial workers in physically demanding tasks. In such scenarios, low mass and compact …

Digital hydraulic drives are known for their superior efficiency, power density, and
robustness. Such advantages make them an attractive alternative (to electric drives) for …

This paper introduces the phenomenon of directional efficiency, a property of spur gear
transmissions in which the coefficient of torque dependent efficiency is function of the power …
