A Brief History of Autonomous Underwater Vehicles
The notion of employing autonomous vehicles for the purpose of underwater exploration traces its origins to the mid-20th century.
It was during this time that the U.S. Navy embarked upon the development of remotely operated underwater vehicles (ROVs) primarily intended for military applications.
These early ROVs were tethered to the surface and controlled by human operators on ships or platforms, limiting their range and mobility.
The real breakthrough in underwater autonomy came in the 1980s when researchers at the Massachusetts Institute of Technology (MIT) developed the first true Autonomous Underwater Vehicle, called “Slocum.”
Slocum, an autonomous underwater vehicle of remarkable innovation, emerged as a self-contained entity untethered to human intervention.
It possessed the remarkable capacity to navigate autonomously, gather valuable data, and resurface without external aid.
With its advent, a new epoch in underwater exploration dawned, catalyzing a transformative shift.
In the wake of this pioneering development, the technology of Autonomous Underwater Vehicles has undergone rapid evolution, progressing swiftly along a trajectory of sophistication and versatility.
How Autonomous Underwater Vehicles Work
Autonomous Underwater Vehicles, distinguished by their capacity to operate sans human intervention, rely upon pre-programmed instructions or artificial intelligence algorithms to orchestrate their navigation, data collection, and task execution.
