The invention provides a soft bionic manta ray. A manta ray body comprises a soft shell, a floating body trunk, a soft belly cover and a floating body tail part. The soft shell is formed by pouring a soft material, the soft shell is composed of a soft trunk and soft pectoral fins symmetrically distributed on the two sides of the soft trunk, and a first soft pectoral fin framework and a second soft pectoral fin framework are arranged in the soft pectoral fins on the two sides; the first soft pectoral fin skeleton and the second soft pectoral fin skeleton are each provided with a plurality of fin ray nerves distributed in a divergent mode, and each fin ray nerve is provided with at least one nerve node. The floating body trunk is mounted in an abdomen opening of the soft trunk, and the soft abdomen cover is used for sealing the opening and enabling the curved surface of the abdomen to be complete and smooth; and the swingable floating body tail part is positioned at the tail part of the soft body. According to the invention, the nonlinear motion of biological manta ray pectoral fins can be simulated, so that the pectoral fins of the manta ray body generate flexible fluctuation deformation, and the underwater wandering posture is closer to the manta ray.
本发明提供了一种软体仿生蝠鲼,蝠鲼本体包括软体外壳、浮体主干、软体腹盖、浮体尾部件。软体外壳利用软体材料浇筑成型,软体外壳由软体躯干以及对称分布于软体躯干两侧的软体胸鳍组成,两侧的软体胸鳍内设有第一软体胸鳍骨架、第二软体胸鳍骨架,第一软体胸鳍骨架、第二软体胸鳍骨架均设置有若干呈发散状分布的鳍条神经,各鳍条神经设有至少一个神经节点;浮体主干安装在软体躯干的腹部开口内,软体腹盖用于将开口密封并使得腹部的曲表面完整且光滑;可摆动的浮体尾部件位于软体躯干的尾部。本发明可以模拟生物蝠鲼胸鳍的非线性运动,使蝠鲼本体的胸鳍产生柔性波动变形,使得水下游行姿态更接近蝠鲼。
