Abstract

The invention discloses a jellyfish-like underwater robot based on a mollusk driver, comprising a sealed cabin at the upper end, a fixing device at the lower end, a control unit and a mollusk propelling unit, wherein the sealed cabin is fixedly connected with the fixing device; the mollusk propelling unit comprises mollusk tentacles and a pipeline connected with the mollusk tentacles; the mollusk tentacles are uniformly and fixedly mounted around the upper end of the fixing device so as to serve as a flexible driver of the whole robot; and the control unit is used for supplying or cutting compressive fluid to the mollusk tentacles through the pipeline to enable single or multiple mollusk tentacles to generate deformation, so that the whole robot turns or moves. According to the jellyfish-like underwater robot disclosed by the invention, the extension and constriction of jellyfish tentacles are simulated by the mollusk tentacles, and the mollusk tentacles are large in deformation amplitude, strong in driving force, high in efficiency and good in application prospect.

Description

technical field [0001] The invention belongs to the field of bionic underwater robots, in particular to a jellyfish-like underwater robot based on software drivers. Background technique [0002] Underwater propulsion technology occupies a very important position in marine transportation, but the most important underwater propulsion technology is still propeller propulsion. Traditional propeller propulsion technology has obvious disadvantages such as low propulsion efficiency, high noise, and low energy utilization. In order to overcome the disadvantages of propeller underwater propulsion, bionic underwater propulsion technology is becoming a research hotspot in recent years. After hundreds of millions of years of evolution, underwater organisms have possessed low energy consumption, high efficiency and other capabilities. The driving modes of underwater organisms can be roughly divided into three categories: body / caudal fin driving mode (BCA), middle / pair fin driving mode ...
