The invention discloses a floating and sinking device for a bionic robotic fish and the bionic robotic fish. The floating and sinking device comprises a base plate and floating and sinking parts. The floating and sinking parts are symmetrically arranged on the two side surfaces of the base plate. Each floating and sinking part comprises a dielectric elastomer film layer, an electrode layer, a conductive assembly and an elastic assembly. The dielectric elastomer film layer is arranged on the base plate, and an arc-shaped first cavity is formed between the dielectric elastomer film layer and the base plate; the electrode layer wraps the dielectric elastomer film layer; the conductive component is electrically connected with the electrode layer; and one end of the elastic assembly is arranged on the base plate, and the other end is connected to the dielectric elastomer film layer. According to the floating and sinking device for the bionic robotic fish, the size of the floating and sinking device can be changed by controlling a voltage value of an external power source connected to the conductive assembly so as to change the buoyancy of water borne by the bionic robotic fish, and then the floating, floating stopping and sinking actions of the bionic robotic fish are achieved. Therefore, the floating and sinking principle similar to that of fishes is achieved, and the bionic performance of the floating and sinking device is better.

    本发明公开了一种用于仿生机器鱼的浮沉装置及仿生机器鱼,包括基板和浮沉部件;浮沉部件对称设置在基板的两侧面;浮沉部件包括:介电弹性体薄膜层、电极层、导电组件以及弹性组件;介电弹性体薄膜层设置在基板上,介电弹性体薄膜层与基板之间形成弧形状的第一空腔;电极层包裹设置在介电弹性体薄膜层上;导电组件与电极层电连接;弹性组件一端设置在基板上、另一端连接于介电弹性体薄膜层。本发明实施例中的用于仿生机器鱼的浮沉装置可通过控制接入导电组件的外部电源的电压值改变其体积以改变仿生机器鱼所受水的浮力,进而实现仿生机器鱼的上浮、浮停以及下沉的动作。从而实现与鱼类相似的浮沉原理,因此所述浮沉装置的仿生性能更佳。
