The invention belongs to the technical field of bionic soft propellers, and discloses a bionic duck web propeller based on fluid driving and a manufacturing process of the bionic duck web propeller. The bionic duck web propeller structure comprises a duck web structure and a duck leg structure, the duck web structure is composed of webs and duck fingers, each duck finger comprises a plurality of liquid cavities arranged in parallel, the duck fingers can be bent and deformed under the driving of high-pressure fluid, the contact area of the propeller and water is increased through the web structures, and therefore the propelling force of the propeller is improved; the duck leg structure is similar to the duck finger structure and can be bent and deformed under the driving of high-pressure fluid, so that the whole duck web structure is driven to move. The bionic duck web soft propeller is made of the same soft material and has the advantages of being good in flexibility and environmental adaptability, and the duck legs and the duck finger structures are provided with independent liquid inlets/outlets, so that the propeller can achieve the functions of small-amplitude slow movement, large-amplitude rapid movement, steering and the like.

    本发明属于仿生软体推进器技术领域,其公开了一种基于流体驱动的仿生鸭蹼推进器及其制作工艺。所述仿生鸭蹼推进器结构包括鸭蹼结构和鸭腿结构,鸭蹼结构由蹼和鸭指组成,其中鸭指包含若干个平行排列的液腔,在高压流体的驱动下鸭指可以产生弯曲变形,蹼结构有利于增加推进器与水的接触面积,从而提升推进器的推进力;鸭腿结构与鸭指结构类似,在高压流体的驱动下同样可以产生弯曲变形,从而带动整个鸭蹼结构的运动。本发明的仿生鸭蹼软体推进器使用同种软体材料制成,具有柔顺性好、环境适应性好的优点,且鸭腿和各鸭指构具有独立的进/出液口,使得推进器可以实现小振幅的缓慢运动、大振幅的快速运动、转向等功能。
