Weights & Biases - Autonomous underwater vehicles: small, powerful & efficient
Autonomous underwater vehicles (AUVs) are designed without the need for life support systems, which significantly reduces their size and complexity compared to manned submarines. This allows AUVs to be much smaller, enabling them to access areas that human-operated vehicles cannot. These vehicles are equipped with batteries, sensors, and onboard computing systems, allowing them to perform various tasks autonomously. They are typically cylindrical with a propeller and control surfaces, and they use sensors and sonar to navigate and detect objects in their environment. The absence of human life support systems means they can be pre-programmed for specific missions, enhancing their efficiency and utility in underwater exploration and data collection.
Key Points:
