Exploring the Feasibility of Solar-Powered Autonomous Underwater Survey Vehicles for Extended Underwater Exploration

Autonomous Underwater Vehicles (AUVs) have emerged as vital tools in underwater ecological research. However, challenges such as limited operating range, energy constraints, and communication issues persist. This research investigates the practicality of autonomous survey vehicles by proposing a solution that integrates renewable energy sources, enhances communication capabilities during submersion, and facilitates long-term deployments. The study presents a solar-powered Autonomous Underwater Survey Vehicle (AUSV), comprising a submersible and a tethered solar buoy. The AUSV aims to operate autonomously along predefined paths, ensuring constant communication, extended operation cycles, and efficient data collection. The solar buoy provides GPS tracking, data transmission, and renewable energy generation, eliminating the need for periodic resurfacing. The submersible is equipped with thrusters, sensors, and data acquisition tools for oceanic measurements. The project's focus is on addressing limitations in traditional survey methods, providing an economical and efficient alternative for underwater exploration, with potential applications in ecological studies, water quality testing, and bathymetry. The presented proof-of-concept prototype lays the groundwork for future advancements in underwater infrastructure and scientific exploration.
