arrow-one-3The ROV prototype is designed to carry out underwater surveillance in lakes, harbors and maritime environment, under a remote control system placed onshore or on seaborne platforms. ROV consists of a watertight streamlined body that includes the sensors, projectors and electronic microcontrollers, linked to the remote control station (laptop) via an umbilical cable that transfers data from the vehicle and commands from the operator. ROV is destined to assist divers during reconnaissance operations or to fully replace them in tough hydro-meteorological conditions.

Research and development of the prototype has been accomplished in the “Mircea cel Batran” Naval Academy under a contract awarded by the Romanian Naval Forces.

The novelty of this project is given by the low cost of the ROV. Generally, as these vehicles contain dedicated sensors, controllers, actuators and remote control systems they are expensive enough to be used by large companies that afford them. The authors succeeded in devising a configuration based on off-the-shelf components, thus drastically reducing the building costs for similar performances.

1. Producing a high-power electromagnetic pulse (IEMP), like a lightning air, with much lower costs than those required by classical methods in a specialized laboratory testing of high voltage.

 2. Possibility of a wide range of high power electromagnetic pulses by modifying constructive parameters flux compression generator.

3. Small size, simple design of the generator, independence from a power source.

 4. Low risk of danger to personnel performing specialized  testing microcomputers, compared with the risk involved in producing high voltage installations.
