Embodiment Construction

[0015] Such as figure 1 with figure 2 As shown, the jellyfish bionic robot is composed of a jellyfish head (1), a support seat (2), a flexible shell (4), a floating device (6), a radial memory alloy shrapnel (3) and an axial memory alloy shrapnel (5) ; The flexible shell (4) is a type of hemispherical hollow shell, and a plurality of radial memory alloy shrapnels (3) are evenly distributed in its circumferential direction, and the radial memory alloy shrapnel (3) are under normal conditions The flexible shell (4) is tightly fitted together with glue, and the flexible shell (4) is connected with the support seat (2) through the radial memory alloy shrapnel (3); the lower part of the flexible shell (4) is opened circumferentially There are multiple gaps, which are used to reduce the resistance when the radial memory alloy shrapnel (3) shrinks; a hemispherical jellyfish head (1) is arranged on the top of the support seat (2), and its interior is in a hollow state. A control pa...

Abstract

The invention provides a jellyfish bionic robot. The jellyfish bionic robot comprises a jellyfish head portion, a supporting seat, a flexible shell, radial memory alloy elastic pieces and axial memoryalloy elastic pieces of a floating device; the flexible shell is a hemisphere-like hollow shell, a plurality of radial memory alloy elastic pieces are evenly distributed in the circumferential direction the flexible shell, and a plurality of evenly distributed axial memory alloy elastic pieces are arranged at the lower part of the flexible shell; the axial memory alloy elastic pieces and the radial memory alloy elastic pieces are perpendicular to each other, and the flexible shell is connected with the supporting seat through the radial memory alloy elastic pieces; the hemispheric jellyfish head portion is arranged above the supporting seat, the floating device is installed under the supporting seat, and the floating device and the jellyfish head portion are connected and sealed through threads and are fastened on the supporting seat. The jellyfish bionic robot can not only realize the propelling motion, but also can realize the turning movement similar to real jellyfishes, and has asimple structure and a good bionic effect.

Description

Technical field [0001] The invention relates to the field of bionic robots, in particular to a jellyfish bionic robot. Background technique [0002] At present, with the development of underwater detection and underwater transportation, the development of underwater robots has been paid more and more attention. Among them, the jellyfish-like robot has become a research hotspot due to its unique hydrodynamic propulsion principle. Jellyfish is an invertebrate. Its movement mainly relies on the contraction and elongation of radially distributed muscle fibers, which in turn drives the contraction and stretching of the flexible shell. The water flow moves under the action of the inner cavity of the shell, thereby driving the jellyfish forward. The flexible shell of the jellyfish does not simply shrink radially, but also adjusts its shape according to the direction and force it needs to move forward. After adjusting the shape, the jellyfish can adjust the direction of its moveme...
