\"\"The Remotely Operated Underwater Vehicle (ROUV) project involved the assembly, modification, and testing of a Blue Robotics ROV-2 platform for marine research applications. The unit was fully waterproofed, equipped with leak sensors, GPS, sonar, and a depth-sensing pressure sensor, and rebuilt to integrate new functionality. A custom 3D-printed camera mounting bracket was designed and installed to enhance underwater imaging capabilities. Additionally, multiple environmental sensors were incorporated to expand the vehicle\u2019s ability to collect marine data.<\/p>\n

The project successfully demonstrated the ROUV\u2019s capacity for stable underwater operation, real-time data collection, and adaptability for various marine studies.<\/p>\n

Introduction<\/h3>\n

Marine environments present unique challenges for monitoring and research due to their dynamic and often inaccessible conditions. Traditional sampling methods are limited in scope, making Remotely Operated Vehicles (ROVs) an essential tool for underwater exploration, environmental monitoring, and marine engineering studies. The purpose of this project was to rebuild and upgrade a Blue Robotics ROV-2 to support advanced marine sensing capabilities. By integrating waterproofing measures, leak sensors, navigation systems, and imaging equipment, the ROUV was designed to deliver precise environmental data, reliable navigation, and high-quality visual feedback for applications ranging from water quality assessment to marine ecosystem studies.<\/p>\n

Waterproofing and Leak Detection<\/h3>\n

\"\"A critical part of the rebuild was ensuring the ROUV\u2019s structural integrity and waterproofing. All enclosures and cable feedthroughs were sealed with marine-grade materials to prevent water intrusion under pressure. Additional O-rings and sealing compounds were applied at connection points to withstand prolonged underwater operation.<\/p>\n

To provide real-time safety monitoring, leak detection sensors were installed within the electronics housing. These sensors were programmed to alert the operator immediately in case of water ingress, enabling rapid recovery and preventing damage to sensitive components. Testing showed that the leak detection system responded reliably to simulated breach conditions, making it a robust safeguard for extended missions.<\/p>\n

GPS and Sonar Navigation<\/h3>\n

\"\"\"\"For navigation and situational awareness, the ROUV was equipped with GPS and sonar systems. The GPS module was used at the surface to provide\u00a0accurate location data and track vehicle position during deployment and recovery. Since GPS signals cannot penetrate water, sonar technology was integrated to support underwater navigation, obstacle detection, and depth mapping.<\/p>\n

The sonar system allowed the ROUV to detect nearby structures and avoid collisions, which is particularly important in murky or low-visibility conditions. Together, GPS and sonar provided a hybrid navigation approach that ensured both accurate surface positioning and reliable underwater awareness.<\/p>\n

Environmental Sensors and Camera Mount<\/h3>\n

\"\"To support marine data collection, the ROUV was equipped with pH, temperature, and pressure sensors. The pressure sensor enabled accurate depth measurement, while the pH and temperature sensors provided valuable data for water quality monitoring. A custom-designed and 3D-printed camera bracket was fabricated to mount an underwater camera, enabling real-time video streaming and recording. This integration enhanced both scientific observation and operator control during missions.<\/p>\n

Testing and Performance Evaluation<\/h3>\n

Testing focused on validating the ROUV\u2019s waterproofing, leak detection, navigation accuracy, and sensor functionality. Controlled pool trials confirmed the effectiveness of waterproof sealing, and the leak sensors provided early warnings during simulated fault conditions. The sonar system successfully detected underwater obstacles, while GPS delivered accurate surface positioning data. Depth readings from the pressure sensor were consistent with reference values, and environmental sensors produced reliable measurements. The camera mount proved stable, providing clear footage during underwater maneuvers.<\/p>\n

Results and Discussion<\/h3>\n

The rebuilt ROUV demonstrated stable underwater maneuverability and reliable data collection. The leak detection and waterproofing systems significantly improved operational safety. GPS and sonar integration enhanced navigational capability, while environmental sensors supplied useful information for marine studies. Challenges included limited battery endurance and the need for sensor calibration in varying water conditions, but these can be addressed in future iterations.<\/p>\n

Conclusion<\/h3>\n

This project highlights the adaptability of the Blue Robotics ROV-2 platform when combined with customized design improvements and advanced sensor integration. With its combination of leak detection, waterproofing, GPS, sonar, environmental sensors, and imaging systems, the ROUV is well-suited for marine research, water quality monitoring, and underwater inspection tasks. Future enhancements could include longer battery life, autonomous navigation, and additional water quality sensors to expand its research potential.<\/p>\n
