The project focuses on the design, fabrication, and control of a small Autonomous Underwater Vehicle (AUV) tailored for a variety of applications like underwater exploration, research, and surveillance. The development process involves selecting appropriate materials, designing the vehicle's structure, implementing propulsion and Novigation systems, and integrating sensors for monitoring underwater environments. Control systems are developed to ensure autonomy, accuracy, and safety in various underwater conditions. AdditioNolly, this project aims to enhance the vehicle's energy efficiency and operatioNol longevity, with an emphasis on making it cost-effective and versatile for diverse underwater tasks, ranging from environmental monitoring to defense applications.
