Modelling and Simulation of the Autonomous Underwater Vehicle (AUV) Robot
2015
Autonomous underwater vehicles (AUV) have been used widely in the oceanic applications for many purposes, such as maritime fishery study, the installation of underwater pipelines in the oil and gas industry as well as to support offshore engineering, and mine hunting and defence applications. Projects in the development, manufacturing and testing of AUVs are complex, requiring a large investment of time, money and effort. Therefore, the simulation of the AUVs has been identified as being cost effective and time saving, as simulation is a vital step in understanding the behaviour and operation of the system before its actual deployment in the field. A number of subsystems must be considered for building a successful AUV simulator, these are the Inertial Navigation System (INS), Machine Vision, Sonar, Communication (underwater and on surface), and the Simultaneous Localization and Mapping (SLAM) module systems. This paper discusses the methods and the outcomes of the feasibility study...
Autonomous Underwater Vehicles: Recent Developments and Future Prospects
International Journal for Research in Applied Science and Engineering Technology -IJRASET, 2020
Autonomous Underwater Vehicles (AUVs) have wide range of applications in fields like marine geoscience, military, commercial and policy sectors. Their need and applications increase day by day due to their ability operate autonomously of a host vessel which is well suited for exploration of extreme environment. Thus, research on AUVs have become popular in the present-day scenario. This paper is intended to summarise the developments in the field of AUVs in India and abroad and tends to focus on their future technical developments. I. INTRODUCTION An autonomous underwater vehicle (AUV) is an unmanned underwater self-propelled robot. They are a part of a larger class of unmanned underwater vehicles of which another part is Remotely Operated Vehicles (ROVs). The function of AUVs is to navigate through the water without the assistance of an operator performing surveys and collecting data which is achieved by pre-programming the AUVs at the surface. As against AUVs, ROVs remain tethered to the host vessel and controlled and powered by an operator through an umbilical. AUVs are well suited to geoscience applications requiring constant altitude for their ability to maintain a linear trajectory through the water. Though a ROV can draw more power and communicate real-time data, its speed mobility and spatial range are limited compared to an AUV. AUVs are playing some important roles in important cases since their inception. They have a wide range of application varying from commercial uses, research purposes, military applications, air crash investigations etc. They are used to make detailed maps and surveys of the sea floor (oil and gas industries) before building subsea infrastructure. This helps in installation of pipelines and subsea completions in a cost-effective manner with minimum disruption to the environment as compared to traditional bathymetric surveys which would be less effective or too costly. With increasing advents of technological developments in AUVs, they are used to study lakes, oceans and ocean floors. Some of the practical applications of AUVs are like the absorption and reflection of light and the presence of microscopic, Measurements of the concentration of various elements or compounds. They can also be configured as tow vehicles to deliver customized sensor packages to specific locations. In the field of Defence, AUV has become an efficient tool. A group of AUVs are required to keep a specified formation for gathering intelligence, surveillance and reconnaissance. They have been successfully incorporated into operations like mine countermeasures, payload delivery, anti-submarine warfare, time-critical strike etc. Due to extensive research in the field of AUVs and their application in different fields, there is a need for a deep review in this regard. The current research and development works going on and completed on AUVs and their future prospective are the focus of this paper.
IJERT-Design and Development of an Autonomous Underwater Vehicle VARUNA 2.0
International Journal of Engineering Research and Technology (IJERT), 2020

This paper entails the design and development of an Autonomous Underwater Vehicle named VARUNA 2.0, developed by the undergraduates of Delhi Technological University. The rationale behind the design is to implement and improvise the maneuverability, robustness, stability, and hydrodynamics of the AUV to be able to perform discrete tasks. The AUV is modeled in SolidWorks followed by finite element analysis in Ansys to ensure the AUV sustain the environment it is exposed to. An automatic battery monitoring system is implemented for power optimization along with controlled power distribution. The software stack is built upon ROS framework along with convolution neural network with image processing being handled by OpenCV 3. Real-time analysis resulting in error correcting codes (ECC) assists in smooth navigation in dynamic environments.

The methods of data collection, processing, and assessment of the quality of the results of a survey conducted at the Southern Ionian Sea off the Messinian Peninsula, Greece are presented. Data were collected by the GEBCO-Nippon Foundation Alumni Team, competing in the Shell Ocean Discovery XPRIZE, during the Final Round of the competition. Data acquisition was conducted by the means of unmanned vehicles only. The mapping system was composed of a single deep water AUV (Autonomous Underwater Vehicle), equipped with a high-resolution synthetic aperture sonar HISAS 1032 and multibeam echosounder EM 2040, partnered with a USV (Unmanned Surface Vessel). The USV provided positioning data as well as mapping the seafloor from the surface, using a hull-mounted multibeam echosounder EM 304. Bathymetry and imagery data were collected for 24 h and then processed for 48 h, with the extensive use of cloud technology and automatic data processing. Finally, all datasets were combined to generate a ...
