Embodiment Construction

[0031] Such as figure 1 with figure 2 As shown, the new autonomous bionic robotic fish of the present invention includes a main cabin, which is composed of an upper shell 6 and a lower shell 2. The shape of the main cabin refers to the shape of the boxfish, and the front of the main cabin is streamlined , The left and right sides are concave and streamlined. The upper shell 6 of the main cabin is made of engineering plastics, the lower shell 2 is made of duralumin, and the upper shell 6 and the lower shell 2 are statically sealed and waterproof by an O-ring. Pectoral fin components, caudal fin components, sensing modules, control modules, power supply modules and counterweights are arranged inside the main cabin. A fin-like component is arranged outside the main cabin. The fin-like component includes carbon rod fiber and plastic skin, the carbon rod fiber simulates fish bones, and the plastic skin simulates the film between fish bones. The imitation fin component includes a ...

Abstract

The invention relates to a robot fish for underwater detection tasks, and aims at providing a novel automatic bionic robot fish which is good in self-stability and maneuverability, high in automatic performance and capable of adapting the complex underwater operation environment. The novel automatic bionic robot fish comprises a main cabin. The main cabin is composed of an upper shell and a lower shell which are sealed; a fin simulating assembly is arranged outside the main cabin, and the fin simulating assembly comprises a pair of pectoral fins and a tail fin. The main cabin is internally provided with a pectoral fin assembly, a tail fin assembly, a sensing module and a control module. The pectoral fin assembly comprises a pectoral-fin steering engine fixing mechanism and two pectoral-fin power transmission mechanisms; the tail fin assembly comprises a tail-fin power transmission mechanism and a passive rotating mechanism; the sensing module comprises a visual sensor, an infrared distance sensor, an IMU attitude sensor and a plurality of pressure sensors; the control module comprises a microcontroller, a sensor-information collecting pressing board, a steering engine control unit and a communication unit.

Description

Technical field [0001] The invention relates to a robotic fish, in particular to a novel autonomous bionic robotic fish used for underwater detection tasks. Background technique [0002] Whether it is the exploration of marine resources, the collection of information on changes in seawater, the research of marine biology, or the collection of military investigations and intelligence, all depend on the level of development of underwater technology. As human beings increasingly explore and excavate marine space and seabed resources, traditional underwater propulsion methods can no longer meet the demand. With the development of bionics, electronic technology, material science and control technology, researchers have begun to imitate the movement of natural fish and hope to obtain underwater propellers with excellent swimming performance and high propulsion efficiency like fish. Since 1994, MIT successfully developed the world’s first real biomimetic robotic fish. The bionic roboti...
