ABSTRACT:
The lower extremity exoskeleton comprises two leg supports connectable to person's lower limbs and configured to rest on the ground during their stance phase. Each leg support comprises a thigh link and a shank link; a knee joint configured to allow flexion and extension between the shank link and the thigh link. The lower extremity exoskeleton further comprises an exoskeleton trunk connectable to the person'supper body. The exoskeleton trunk is connectable to the thigh links of the leg supports allowing for the flexion and extension between the leg supports and the exoskeleton trunk. Two torque generators are coupled to each of the knee joints. A power unit, capable of providing power, is coupled to the torque generators. In operation when a leg support is in a stance phase and climbing a slope or stairs, the power unit injects power into the respective torque generator thereby extending the respective knee angle. When a leg support is in stance phase and not climbing a slope or stairs, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to resist flexion of the respective knee joint. When a leg support is in a swing phase, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to minimize its resistance to knee flexion and extension.
