Biomimetic machine fish in multiple modes

Abstract

A bionic machine fish of multimode consists of rigid fish head, flexible fish body with multiple joints and bionic fin mechanism of left and right pectoral fins as well as tail fin. It is featured as setting driving unit of pectoral fins, control circuit, power supply module, radio duplex communication module, infrared sensing unit, ultrasonic distance measuring unit of fish depth in water, small size of transducer and amplification circuit of peripheral wave-filtering in fish head.

Description

technical field [0001] The invention relates to a bionic robot fish, in particular to a multi-mode bionic robot fish controlled by a central pattern generator (CentralPattern Generator, CPG). Background technique [0002] With the rapid development of robot technology, more and more robots are used to help humans develop unknown environments, especially those environments that are difficult for humans to access, such as outer space or the deep sea. In the process of ocean development and exploration, a variety of autonomous underwater vehicles have emerged. However, the best current underwater vehicles are also difficult to adapt to the long time, good maneuverability and high efficiency required for underwater missions. Fish is one of the earliest vertebrates in nature. After hundreds of millions of years of long evolution, its underwater locomotion ability is obviously superior to artificial underwater vehicles in terms of propulsion efficiency, maneuverability, and accel...
