The body of the walker is composed of two portions which are the hip and upper body connecting portion and the hip and leg and foot part connecting portion, wherein the hip and upper body connecting portion comprises the upper body to which a main device control panel is fixed, motors M1 and M2 which are connected with the hip and the upper body and control the included angle between each leg and the upper body, and spring systems R and L, and the hip and leg and foot part connecting portion comprises legs fixedly connected with the hip, feet hinged to the bottom ends of the legs, motors A and B which control the feet to rise and fall, and spring systems A and B with two ends fixed to the legs and middle connected with the motor A and the foot L and also connected with the motor B and the foot R through belts. The walker further comprises sensors placed in all the control units. According to the walker, semi-passive walking is achieved through energy compensation; the legs are straight legs without knees, so that control method is simple; collision between the feet and the ground can be avoided by controlling foot lifting; furthermore, the gait of the passive walker can be affected by the upper body, so that natural and energy-saving walking is achieved.
