A fish-like underwater vehicle with high maneuverability

Abstract

The invention provides a fish-like underwater vehicle with high maneuverability, which comprises a head, a middle section shell, a back section shell, a tail, a first pectoral fin, a second pectoral fin and a head bottom shell. The head part, the middle part shell, the back part shell and the tail part are sequentially connected through the steering gear; The caudal fin is fixed on both sides of the caudal part; The head is provided with a microcontroller, a power supply and a first steering gear; The first pectoral fin and the second pectoral fin are mounted on both sides of the head and connected with the first steering gear through a connecting rod, so that the pitch angle of the first pectoral fin and the second pectoral fin can be adjusted; A first motor and a second motor are mountedon the first pectoral fin and the second pectoral fin, and the lower end of the motor is connected with the propeller. The fish-like underwater vehicle with high maneuverability improves the maneuverability and flexibility of the fish-like underwater vehicle, and improves the obstacle avoidance ability of the fish-like underwater vehicle. Rich motion forms of fish-like underwater vehicle can notonly stabilize forward, but also achieve emergency brake, float up, change the direction of motion quickly, and enhance the adaptability of fish-like underwater vehicle to complex environment.

Description

technical field [0001] The invention relates to the technical field of underwater bionic vehicles, in particular to a fish-like underwater vehicle capable of flexibly avoiding obstacles under high underwater maneuvering conditions. Background technique [0002] With the rapid reduction of terrestrial resource reserves and the gradual increase in the difficulty of mining, more and more countries are turning their attention to the ocean, which contains huge resources. However, at present, most of the practical underwater vehicles developed by countries in the world need to consume a lot of energy, which leads to great restrictions on their underwater operation time and underwater operation area under the condition of limited energy. Therefore, the fish-like underwater vehicle with the characteristics of high propulsion efficiency, small resistance, flexible action, and high maneuverability has become one of the hot spots in the research of underwater vehicles today.

AI Technical Summary

Problems solved by technology

However, compared with the nearly ideal experimental conditions, the conditions in the real environment are more complicated, and there are many unexpected situations. Sexual control ability has put forward higher requirements

However, most of the current fish-like underwater vehicles have low maneuverability and flexibility when avoiding obstacles and resisting external disturbances. After being impacted by high-speed swimming creatures in the water and other external disturbances, the adjustment period is too long and the stability is poor. And other issues
