Abstract
This project presents the design and fabrication of a cost-effective submersible Remotely Operated Vehicle (ROV) intended for underwater exploration, specifically for lakebed surveys and crack observations. The study aims to develop an affordable, durable, and highly maneuverable ROV using a syringe-actuated buoyancy system, PVC hull construction, and a combination of propellers and pumps for navigation. Unlike conventional ROVs that rely solely on thrusters, this design integrates a novel buoyancy control mechanism to enhance precision and stability in shallow water operations.
The development process involved conceptualizing the structural framework, selecting appropriate materials, and integrating propulsion, control, and buoyancy systems. The ROV was fabricated using lightweight and corrosion-resistant materials such as PVC pipes and acrylic plates, ensuring durability and cost efficiency. A single brushless motor provided forward propulsion, while four strategically placed syringe-actuated pumps enabled controlled vertical and lateral movement. The prototype underwent rigorous testing to evaluate maneuverability, depth control, and structural integrity. Results demonstrated that the ROV successfully achieved stable and precise movements, making it an effective tool for underwater inspections. The syringe-actuated buoyancy system provided reliable depth control, although minor delays in response time were noted. While the design proved efficient for shallow-water exploration, enhancements in power efficiency and material optimization are recommended for future iterations. Overall, this project contributes to the advancement of affordable underwater robotics, offering a practical solution for research, environmental monitoring, and industrial applications
