A follow robot is disclosed. The follow robot comprises body, head, limbs and muscles same as or proportional with human's body, head, limbs and muscle in shape, size, Specific Gravity (SG) and Center of Gravity (CG). The follow robot's joints are same as or proportional with human's joints and can turn around to reach same angle as human's joints. The follow robot's head, body, limbs, bones and joints possess the same or proportional support ability as human's head, body, limb, bones and joints, and are droved by artificial muscle, step motor, hydraulic pressure component. Many position and distance sensors are mounted on or around a man, which measure any action of the man continuously. These movement signals are collected by a Personal computer (PC) and transmitted to the follow robot. Following these signals, the follow robot repeats every movement of the man, acts exactly same as the man. Many sensors are also mounted on the follow robot; they are eyes, ears, skin and noses of the follow robot. Any thing the follow robot seeing, hearing, feeling and smelling will be converted to digital signal and transmitted to the man by the PC. The man can see, hear, feel and smell any thing around the fellow robot real timely, and respond to it immediately.
