Let’s start a historical voyage tracing the evolution of Autonomous Underwater Vehicles (AUVs) aka Unmanned Underwater Vehicles (UUV). AUVs are pioneering robots which have discreetly revolutionized underwater exploration. Early conceptions in the latter half of the 20th century led to the sophisticated marvels of the 21st century. As with all new technology, the question of “What are AUVs used for?” has numerous answers and future potential.
