Autonomous Underwater Vehicles (AUVs)

AUVs are self-propelled, unmanned underwater robots that operate without real-time input from an operator. They are equipped with various sensors and navigation systems that allow them to perform tasks such as mapping, surveying, and data collection autonomously. Recent technological advancements in AUVs include improved battery life, enhanced navigation algorithms, and advanced sensing capabilities, making them indispensable tools for ocean engineers.

Remotely Operated Vehicles (ROVs)

ROVs are tethered underwater robots controlled by operators on a surface vessel. These vehicles are commonly used for tasks requiring precise manipulation, such as inspection, maintenance, and repair of underwater structures. Innovations in ROV technology have led to improved maneuverability, better camera systems, and more sophisticated robotic arms, allowing for more complex and delicate operations.

Hybrid Underwater Vehicles

Combining features of both AUVs and ROVs, hybrid underwater vehicles offer the best of both worlds. These systems can operate autonomously or be controlled remotely, providing flexibility for a wide range of applications. For example, they can perform autonomous surveys and then switch to manual control for detailed inspection or intervention tasks. The versatility of hybrid vehicles makes them valuable assets in subsea operations.
