The science and technology of wearable robots are steadily advancing, and the use of such
robots in our everyday life appears to be within reach. Nevertheless, widespread adoption of …

Robotic leg prostheses and exoskeletons have traditionally been designed using highly-
geared motor-transmission systems that minimally exploit the passive dynamics of human …

Robotic ankle-foot prostheses aim to improve the mobility of individuals with belowknee
amputations by closely imitating the biomechanical function of the missing biological limb …

Direct-drive motors (DDMs) have been increasingly used for robot actuation because they
provide high-fidelity torque control, but they typically have low torque density. Gearing can …

Background A mechanical ankle–foot prosthesis (Talaris Demonstrator) was developed to
improve prosthetic gait in people with a lower-limb amputation. This study aims to evaluate …

Wearable robotic devices often need electrical energy. An interesting idea is to collect
mechanical energy during walking and convert it into electrical energy to recharge these …

This letter outlines the modelling, design, and experimental validation of a novel power-
efficient actuator for an active ankle-foot orthosis (AAFO). The actuator is based on a new …

The use of powered ankle-foot prostheses for below-knee amputees leads to challenges like
the peak power of the applied actuator and biomechanical features of the prosthesis foot …

There are different alternatives when selecting removable prostheses for below the knee
amputated patients. The designs of these prostheses vary according to their different …

Energy efficiency is crucial in develo** transtibial prostheses, encompassing two main
aspects: amputee metabolic cost and prosthetic energy consumption. The parallel elastic …
