The bionic bat ray breast fin device is characterized in that an electronic cabin (7), a camera shooting cabin (6) and a battery pack cabin (9) are arranged inside the base body (1), the base body (1) is wrapped by a bionic mantle (2), the front part of the base body (1) is provided with the camera shooting cabin (6), the side of the base body is provided with a flexible bionic bat ray breast fin (4), and the tail part of the base body (1) is provided with a tail fin (5), a bionic nozzle (10), a bionic water inlet film (10) and a water cabin (8).
the camera cabin (6) comprises a pressure-resistant cover, a camera holder and a camera, and the camera cabin is controlled by the electronic cabin.
The battery pack compartment (9) comprises a lithium battery pack.
The wireless communication module uses a Bluetooth module and can remotely receive real-time data collected by the camera.

Therefore, the device is switched between two different modes of driving in a common bat ray mode and spraying the bionic mantle, and the capability of flexibly turning in a narrow water area and propelling at a high speed in a wider water area is considered.
When the underwater robot is in a common bat ray robotic fish driving mode, the main control module controls the flexible bionic bat ray pectoral fins (4) to keep regular swinging and keep real-time rotation of the tail fins (5) at any time, when the underwater robot is in a bionic mantle jet state, the main control module controls the flexible bionic bat ray pectoral fins (4) to be furled and close to a base body, a bionic water inlet film starts to enter water, and relative jet frequency is kept to jet through a bionic nozzle, so that the bionic bat ray pectoral fins reach large acceleration in a short time. In this embodiment, adopted independent 360 degrees pivots to connect bionical pectoral fins to being equipped with independent motor and driving, can fully imitate the motion condition of bat ray under water, in addition can also satisfying the requirement that two kinds of drive mode of this robotic fish switch, switch to corresponding membrane injection in-process promptly, can effectively guarantee the level of pectoral fins and fix.
Specifically, when the robotic fish is driven in a traditional bat ray mode, the pectoral fin firstly raises an angle of 45 degrees and then restores a horizontal posture according to a flapping cycle, then the bionic pectoral fin is inclined downwards by an angle of 45 degrees and continuously restores the horizontal posture to complete a continuous motion cycle, when the bionic pectoral fin reaches the maximum vertical pitch angle, the deformation quantity is also the maximum, and when the pectoral fin is in the horizontal posture, the deformation quantity is the minimum, the speed of the robotic fish is the maximum, the flapping frequency of the whole pectoral fin is 1.0Hz, the flapping amplitude is 18 degrees, and when the bionic membrane injection state is switched, an advancing switching module in an electronic cabin sends out a signal, a pitch control module is regulated to adjust the swimming direction of the robotic fish, the inclination angle and a swimming propulsion module control the bionic pectoral fin, and the tail fin keeps horizontal and static.
