摘要： A powered exoskeleton includes a leg part and a foot part. The foot part includes a foot bottom plate and a foot bottom plate driving wheel. The foot bottom plate includes a first surface and a second surface opposite to each other; and the foot bottom plate driving wheel is connected below the leg part. The foot bottom plate is movably connected to the foot bottom plate driving wheel and capable of being turned over relative to the foot bottom plate driving wheel. In the walking mode, the foot bottom plate is turned over till the first surface of the foot bottom plate faces upward and is connected below the foot bottom plate driving wheel; and in the wheeled movement mode, the foot bottom plate is turned over till a second surface of the foot bottom plate faces upward and is connected above the foot bottom plate driving wheel.
