In recent years underwater robotics has become a major area of research owing to the development of many diverse technologies. Autonomous underwater vehicles (AUVs) are used today for exploration, pipeline monitoring, military reconnaissance and other scientific tasks. AUVs can also be used effectively to teach principles in many disciplines of science ranging from physics to robotics. Any good...

Underwater robotics addresses the problem of object detection apparatus. Offers a probabilistic formulation of the problem, which uses the reduction of the detection task to a classical task of Buffon. This formulation arises naturally in the formulation of the problem in the coordinate system associated with the apparatus. It is shown that the problem allows analysis in the presence of an asym...

In this paper a new approach for the underwater sensor network based on the blue-green laser has been proposed. We describe the application of the underwater sensor network in the undersea exploration, and discuss the difficulties in the traditional the underwater acoustic sensor network. A basic of prototype of underwater laser sensor network has been advanced, which include the architecture o...

The research on underwater systems has gained an immense interest during the last decades with applications taken place in many fields such as exploration, investigation, repair, construction, etc. Hereby, control of underwater systems has emerged as a growing field of research. Underwater vehicles, in fact, accounted for 21% of the total number of service robots by the end of 2004, and are the...

Investigation of the waves generated by underwater disturbances gives precious insight into the effect of man-made underwater explosions as well as natural phenomena, such as underwater volcanoes or oceanic meteor impact. On the other hand, prediction of the effects of such waves on the coastal installations and structures is required for preparation worthwhile criteria for coastal engineers to...

in the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. in this study, hydrodynamic coefficients of an autonomous un...

The limitations of underwater acoustic communications mean that the side-scan sonar data an autonomous vehicle (AUV) cannot be transmitted back and processed in real time, which means targets detected time. To address problem, this paper proposes vehicle-based real-time detection method for targets. First, describes system operation underwater-target by mounted on vehicle. Next, it a processing...

Bangsring Beach is one of the leading tourist destinations in Banyuwangi Regency. which focuses on underwater tourism (Bangsring Underwater) a coral reef-based that can only be accessed by diving and snorkeling. But way to enjoy Underwater tourism, construction 12 m catamaran with bottom glass carried out so tourists who cannot dive snorkel beauty Underwater. To ensure comfort safety passengers...

Laser sensing has been applied in various underwater applications, ranging from underwater detection to laser underwater communications. However, there are several great challenges when profiling underwater turbulence effects. Underwater detection is greatly affected by the turbulence effect, where the acquired image suffers excessive noise, blurring, and deformation. In this paper, we propose ...

In this paper, we propose a novel technique to reconstruct 3D surface of an underwater object using stereo images. Reconstructing the 3D surface of an underwater object is really a challenging task due to degraded quality of underwater images. There are various reason of quality degradation of underwater images i. e. , non-uniform illumination of light on the surface of objects, scattering and ...
