Despite enhancements in the development of robotic systems, the energy economy of
today's robots lags far behind that of biological systems. This is in particular critical for …

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 …

As the essential technology of human-robotics interactive wearable devices, the robotic
knee prosthesis can provide above-knee amputations with functional knee compensations …

Walking behaviour in amputees with lower-limb loss is absent from shock-absorbing
properties. A damper can be used to reduce the impact of ground reaction force (GRF) …

Compliant actuators are increasingly being designed for wearable robots (WRs) to more
adequately address their issues with safety, wearability, and overall system efficiency. The …

Several works have shown that series and parallel elasticity can reduce peak power and
energy consumption in prosthetic ankles. Setting the right stiffness of the elastic elements is …

Transfemoral amputees demand a mechatronic lower limb prosthesis as technical substitute
for restoring their gait functions. Prosthetic knee is the key component of a transfemoral …

The CYBERLEGs Beta-Prosthesis is an active transfemoral prosthesis that can provide the
full torque required for reproducing average level ground walking at both the knee and ankle …

Quasi-stiffness characterizes the dynamics of a joint in specific sections of stance-phase and
is used in the design of wearable devices to assist walking. We sought to investigate the …

This paper investigates the use of discrete couplings in series elastic actuation in order to
increase variability of dynamic legged robot locomotion. The couplings are capable of …
