The invention discloses a prosthetic electric smart 
manipulator. The prosthetic electric smart 
manipulator comprises an electric 
thumb, four electric fingers and a mechanical palm, wherein the electric 
thumb and the four electric fingers respectively sequentially an upper 
metacarpophalangeal joint, a middle 
metacarpophalangeal joint, a lower 
metacarpophalangeal joint and a base body, the lower metacarpophalangeal joints of the four electric fingers are respectively arranged in the mechanical palm in the same direction by virtue of the respective base bodies, the lower metacarpophalangeal joint of the electric 
thumb is arranged in the mechanical palm by virtue of the base body of the electric thumb, the electric thumb is positioned at the other side of the mechanical palm, and the five electric fingers and the mechanical palm are in the same plane; and the electric thumb has four driving 
degrees of freedom, each electric finger has three driving 
degrees of freedom and one driven degree of freedom, so that sixteen driving 
degrees of freedom and four driven degrees of freedom are formed in total, are consist with the degrees of freedom of a hand, thus a hardware device is provided for master-slave control of the 
manipulator. According to the invention, arrangement in a bionic hand shape, skeleton structure of fingers of the hand and movement 
functional design of the fingers of the hand are adopted, thus the manipulator in the invention not only can be applied to the industrial field but also can be used as an artificial limb of the hand.
