Application of Unmanned Operating Systems in the Underwater Field

Underwater topographic and water quality data play a vital role in aquatic ecological protection, resource exploration, and scientific research. However, conventional survey methods — such as manned submersibles or tethered robots—are often constrained by limited mobility, short battery life, and operational complexity. To overcome these challenges, this project introduces an intelligent, solar-powered underwater robot designed for untethered operation. It is equipped with autonomous mobility for stable movement at various depths, high-definition imaging for real-time video transmission, a robotic manipulator for precise sampling, and sensors for in-situ measurement of key water parameters including pH and dissolved oxygen. A major innovation lies in its solar charging capability. Flexible solar panels are installed on the robot’s exterior, allowing it to recharge while floating on the water surface. This feature significantly enhances endurance, reduces environmental impact, and supports long-term missions. The robot offers an efficient, sustainable, and versatile platform for underwater exploration, ecological monitoring, and educational applications.
