There is a small submarine floating in the water with a camera attached to it

This is an underwater robot specially designed for river and water environments. It has a compact and robust hull structure to adapt to the special conditions of the river. The hull adopts a streamlined design to reduce the resistance of the water flow and improve the handling and efficiency of the robot. The robot is equipped with advanced underwater sensor systems, including ultrasonic sensors, water temperature sensors, and water quality sensors, which are used to monitor and measure various parameters of the river water environment. The ultrasonic sensor is located in the front of the robot and can accurately measure the distance to the bottom of the river, helping the robot avoid obstacles and shallow water areas. Water temperature sensors can monitor river water temperature changes in real time, providing critical information about the river ecosystem. Water quality sensors detect the amount of chemicals in the water and help assess the quality and environmental condition of river water. The robot's propulsion system features an efficient propeller design to provide powerful thrust and flexible handling. The rudder control system controlled by the servo is located at the rear of the robot, which can realize the forward, backward, left and right turn operation of the robot to adapt to different river environments and task needs. This underwater robot has a wide range of application potential in river water environments. It can be used in the fields of river water quality monitoring, bottom geological exploration, aquatic biological investigation and environmental research. Robots can navigate the river with ease, collecting data, sampling and performing tasks that provide vital support for river management and conservation. --auto --s2
