The invention discloses a bionic robotic fish with a variable tail fin area. The bionic robotic fish comprises a fish head; the fish body is connected to the fish head; the tail fin comprises a main tail fin body and a first adjustable auxiliary tail fin body which are arranged in an overlapped mode, the overlapped parts of the first adjustable auxiliary tail fin body and the main tail fin body are attached to each other, and the end, close to the fish body, of the first adjustable auxiliary tail fin body is pivoted to the main tail fin body so that the first adjustable auxiliary tail fin body can swing up and down relative to the main tail fin body; the first driving device is arranged in the fish body and is in transmission connection with the main tail fin, and the first driving device can drive the main tail fin to swing in the horizontal direction so as to drive the tail fin to swing in the horizontal direction; the second driving device is arranged in the fish body and is in transmission connection with the first adjustable auxiliary tail fin, and the second driving device can drive the first adjustable auxiliary tail fin to swing up and down relative to the main tail fin. According to the bionic robotic fish with the variable tail fin area, the burden generated when the tail fin swings can be reduced, the influence on the swinging action of the tail fin can be reduced, and meanwhile the area of the tail fin can be rapidly changed.
本发明公开了一种尾鳍面积可变的仿生机器鱼,包括:鱼头;鱼身,鱼身连接于鱼头;尾鳍,包括重叠设置的主尾鳍和第一可调节副尾鳍,第一可调节副尾鳍与主尾鳍重叠的部分相互贴合,第一可调节副尾鳍靠近鱼身的一端枢接于主尾鳍,以使第一可调节副尾鳍能够相对主尾鳍上下摆动;第一驱动装置,设于鱼身内部并与主尾鳍传动连接,第一驱动装置能够驱动主尾鳍沿水平方向摆动以带动尾鳍沿水平方向摆动;第二驱动装置,设于鱼身内部并与第一可调节副尾鳍传动连接,第二驱动装置能够驱动第一可调节副尾鳍相对主尾鳍上下摆动。上述的尾鳍面积可变的仿生机器鱼能够减小尾鳍摆动时的负担,而且能够减小对尾鳍摆动动作的影响,同时能够较快地改变尾鳍的面积。
