Mini-submarines are relatively small, submersible vessels designed for underwater exploration, research, tourism, or specific tasks like search and rescue or underwater construction. Unlike larger submarines, they often operate at shallower depths and have a smaller crew capacity, frequently accommodating one to several individuals. Their compact size allows for greater maneuverability in tight spaces and access to environments inaccessible to bigger counterparts. Constructed from robust materials like steel or composites, mini-submarines are equipped with life support systems, propulsion, navigation, and communication technologies. The use of battery or diesel-electric power is typical, and they often feature observation ports, cameras, and robotic arms for visual inspection and manipulation of objects underwater. These vessels offer an unparalleled ability to study marine life or examine wreckage. The application of mini-submarines offers a distinct and unique solution to challenging and exciting oceanographic tasks.
