The utility model relates to a novel distance control multi-joint bionic fish-bots, which is formed of a fish shape casing, a plurality of skeleton frames, a battery and a receiving and controlling circuit board. Each of the skeleton frames is formed of a control actuator, a fixing frame and an oscillation connecting frame. The end of the front oscillation connecting frame is connected with the front end of the control actuator of the back skeleton frame. The structure is simple and the operation is convenient. When the fish-bots is put into water, the movement of the skeleton frame is controlled by the controlling signal radiated from the distance control device to the receiving and controlling circuit, and the initiation of the movement of the real fish is completed, the swimming intellectualization of the fish-bots in water is realized, and the observation character and interest character of the fish like toy are strengthened.
