Abstract

Axial juxtaposed annular shape memory alloy-driven robotic jellyfish, which relates to a bionic robotic jellyfish to solve the complex structure of the existing mechanical bionic jellyfish and the small range of motion of the bionic robotic jellyfish, which is quite different from the bionic propulsion behavior of real jellyfish The big problem, it includes power supply and control and communication module, it also includes flexible shell, cylindrical abdominal cavity, gyratory base, control and communication module and several annular shape memory alloy driving parts; each annular shape memory alloy driving part is composed of shape Composed of memory alloy wire and an open annular flexible tube wrapped with shape memory alloy wire, several annular shape memory alloy driving parts are respectively embedded in the peripheral side of the flexible shell; the cylindrical abdominal cavity and the base of the rotator are detachably sealed and connected, power supply and control and communication The module is placed in the cylindrical abdominal cavity. The invention is used for making the bionic jellyfish machine.

Description

technical field [0001] The invention relates to a bionic jellyfish robot, which belongs to the field of bionic jellyfish robots. Background technique [0002] As a typical prototype of jet propulsion, jellyfish is one of the oldest swimming organisms that exist on the earth, and it exists widely in various regions of the ocean. After long-term evolution, they can adapt to most complex ocean current environments, thanks to their unique hydrodynamic propulsion mechanism. Compared with other fishes with wavy body swimming or tail fin swing propulsion, jellyfish has higher transport efficiency and superior concealment performance. The jellyfish in the natural environment mainly rely on the contraction and elongation of radially distributed muscle fibers to drive the contraction and stretching of the flexible shell, and at the same time drive the movement of the water flow in the inner cavity of the shell. Driven by the reaction force of the water flow, it can complete the forwa...
