Current active foot prostheses try to emulate the foot function by using a mono-articular series elastic actuator (SEA). In humans, a bi-articular actuation scheme is used to plantar-flex the foot through Soleus and Gastrocnemius muscles (in plantar-flexion the angle between foot and shank increases). In this study we investigated on using a bi-articular actuation scheme in active foot prostheses (where a passive bi-articular spring is added to an active mono-articular actuator). For design of… CONTINUE READING
