Robot for Under Water Monitoring

Abstract

Unmanned underwater vehicle is the branch of robotics which comes under the autonomous underwater vehicle. These robots have the wide applications like research, collection of the samples and observation of underwater bodies. The proposed work involves underwater robot for measuring the parameters of water and surveillances for inspecting underwater structure. The contamination of the water bodies can be found out by using the light density method. The evaporation level of water bodies can be studied through temperature measurements and also the acidic and alkaline nature of the water can be seen through pH measurement. To move easily through any standard inspection doors, the robot is designed with the length of 240 mm, breadth 94.68mm and height of 130mm by considering the mass to length calculation method based on floating theory. In addition, this robot is fitted with air tubes of dimension 81.5mm which is a standard size for 5kg robot. This work makes use of Arduino UNO commands to control the motors, light density measurement and water sample collection and communication through Bluetooth communication between the user and the float which floats on the surface of water. The customized mobile application makes the robot user friendly and easily controllable. In this work, an underwater 4K ultra HD camera is fitted to the hardware. This camera is used to record the underwater view. The recorded sequences of images stored in micro SD card are used to analyze surrounding objects in the target area. All the elements connected to the Arduino are controlled by the user. The robot is designed for monitoring the under water.
