Autonomous catching fish school robot fish and its control method for fish school farming

Abstract

The invention discloses an automatic fish school chasing robot fish for the fish school breeding industry and a control method thereof. A robot fish head is internally provided with drainage needle pipes, drainage steering engines, crank blocks and a camera which are connected; the drainage steering engines are connected with pistons of the drainage needle pipes through the crank blocks; and the drainage needle pipes are symmetrically arranged inside the robot fish head. The robot fish head is connected with a robot fish body through a connection bracket. The robot fish body is internally provided with a plurality of driving steering engines which are connected through concatenation fixing pieces; the driving steering engine mostly close to a robot fish tail is connected with the robot fish tail through the corresponding concatenation fixing piece; skin frames for supporting skins are fixed to the concatenation fixing pieces; and the driving steering engine close to the robot fish tail is driven by the driving steering engine close to the robot fish head to rotate in the horizontal direction. The camera, the drainage steering engines and the driving steering engines are connected with a controller. According to the automatic fish school chasing robot fish for the fish school breeding industry, the swimming velocity is increased through mechanical structure improvement and reasonable movement planning, and the output efficiency is improved.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a robotic fish for autonomously chasing fish schools and a control method thereof for the fish school breeding industry. Background technique [0002] Robot fish, hence the name, is a fish-like machine made of materials. Robot fish has been widely used in the field of water quality monitoring. This type of robot fish is usually equipped with chemical sensors to analyze pollutants in water, etc. . This type of robotic fish is intended to be used in aquaculture to drive fish shoals regularly, so that fish shoals can swim regularly, the meat quality can be improved, and the market benefits can be increased. [0003] The current driving methods of robotic fish are often based on bionics, which are mainly divided into the following three types: [0004] a. Anguilliform: (Eel-like) Swimming by undulation of the muscles of the whole body, like an eel [0005] b. Carangiform: Swimmin...
