Abstract:
Variety of mechanisms have been created currently to simulate the
walking activilies of human body, and are mainly used in mobile robots.
According to the specific requirements of reestablishing human walking
functions and by studying the physiological structure of knee joint, we
present in this article a planar linkage mechanism whose outline is
similar to the lower limbs. This mechanism is able to imitate
approximately the flexion and extension movements of hip, knee and ankle
joints during a walking cycle. Walking aid mechanical device using this
relatively simple mechanism would make the paralysis limbs to produce
coordinate movements corresponding to the movements of normal joints.
The aim of this design is creating a pratical device which enable the
patient’s lower extremities to take some physical exercise during the
process of locomotion
