Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with the development of vehicle design, fabrication and testing of the micro class tethered remotely operated vehicle (ROV) for underwater exploration. It will emphasize on the development of tri-thruster ROV. This will be a new type of design where the ROV will have two motors mounted at the front. Its layout is very different from other conventional ROV which have two horizontal motors mounted at the rear. The development accentuate on mechanical approach. The ROV developed will have hydrodynamic features add to it. The prototype is modeled using SOLIDWORKSTM and the further analysis of the model was done using COSMOSFloWorksTM. The quantitative analyses done has determined limiting factor for the ROV as it is desired to be operational in both sea and fresh water for a limited depth. For the fabrication purpose, this project will proceed with PVC pipe as its main component for frame. In methodological section, objective of material selection was to reduce fabrication cost without reducing the performance. The type of onboard control method used simple circuit of double pole double throw (DPDT). Simple circuit were chosen as it is easier to troubleshot and provide more reliability in executing motion compare to complex coding. From COSMOS analysis, the hydrodynamic cover performs very well in decreasing the drag force of developed vehicle. Guided by preliminary result and initial specification, a handmade fabrication will be done to create a prototype to show how this innovative ROV behave underwater, how its drive system response, how the control is functioned and how the motions are perform. The real time testing then runs and the testing bed preferred were surrounding area and control environment. The result was than recorded in video and examination done base on the recorded motion. From real time analysis, the hydrodynamic cover effectively smoothen the prototype motion at underwater and within water surface. The fabricated model can submerge, resurface, move forward and reverse, rotate to left and right. The result of this development will be significantly improved the existing design of ROV and pioneering the future development of remotely operated vehicle for underwater exploration. The fabricated model has installed camera and the first to be equipped with oblique hydrodynamic cover and frontal thruster layout. The development in phrase can be concluded as an innovation of design and invention of layout.

Download or read book Deterministic Artificial Intelligence written by Timothy Sands and published by BoD – Books on Demand. This book was released on 2020-05-27 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kirchhoff’s laws give a mathematical description of electromechanics. Similarly, translational motion mechanics obey Newton’s laws, while rotational motion mechanics comply with Euler’s moment equations, a set of three nonlinear, coupled differential equations. Nonlinearities complicate the mathematical treatment of the seemingly simple action of rotating, and these complications lead to a robust lineage of research culminating here with a text on the ability to make rigid bodies in rotation become self-aware, and even learn. This book is meant for basic scientifically inclined readers commencing with a first chapter on the basics of stochastic artificial intelligence to bridge readers to very advanced topics of deterministic artificial intelligence, espoused in the book with applications to both electromechanics (e.g. the forced van der Pol equation) and also motion mechanics (i.e. Euler’s moment equations). The reader will learn how to bestow self-awareness and express optimal learning methods for the self-aware object (e.g. robot) that require no tuning and no interaction with humans for autonomous operation. The topics learned from reading this text will prepare students and faculty to investigate interesting problems of mechanics. It is the fondest hope of the editor and authors that readers enjoy the book.

Download or read book Benchmark Models of Control System Design for Remotely Operated Vehicles written by Cheng Siong Chin and published by Springer Nature. This book was released on 2020-08-07 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to meet the needs of those who seek to develop control systems for ROVs when there is no model available during the initial design stage. The modeling, simulation and application of marine vehicles like underwater robotic vehicles (URVs) are multidisciplinary, and combine mathematical aspects from various engineering disciplines. URVs such as remotely operated vehicle (ROVs) are used for a wide range of applications such as exploring the extreme depths of our ocean, where a hard-wired link is still required. Most ROVs operate in extreme environments with uncertainties in the model prior to control system design. However, the method involved extensive testing before the system model could be used for any control actions. It has been found that the range of error can be extensive and uncertain in actual, continuously varying conditions. Hence, it is important to address the problem of reliance on model testing using different modeling approaches. In this book, approaches such as WAMIT, ANSYS-CFX, STAR CCM+, MATLAB and Simulink are used to model parameters for ROVs. A few benchmark models are provided, allowing researchers and students to explore and test different control schemes. Given its scope, the book offers a valuable reference guide for postgraduate and undergraduate students engaged in modeling and simulation for ROV control.

Available in PDF, EPUB and Kindle. Book excerpt: There is now an awareness within the industry, particularly as oil companies direct considerable resources towards developing diverless production systems, that a fully integrated approach to equipment design and intervention is necessary to achieve an acceptable system. The requirement for an integrated approach to equipment design and intervention is applicable not only to diverless depths but to all subsea structures, equipment and intervention techniques in whatever depth. Fortunately the inherent dexterity of the diver does not impact so severely on design as other intervention techniques. However the benefits of an integrated approach are still applicable and the use of such simple "diver aids" as cutting guides and subsea markings installed prior to the installation of jackets and subsea equipment can have a significant impact on the cost of intervention. This paper examines the requirements and limitations in designing subsea equipment for Remotely Operated Vehicle (ROV) intervention. For the oil company embarking on the development of a diverless production system, be it totally diverless because of the envisaged water depth or primarily diverless with the possibility of diver back up, the intervention techniques adopted will strongly influence the final system design. The necessity to undertake an extensive development programme to produce the optimum intervention system is very costly, requires long lead times and comprehensive testing particularly where novel solutions are adopted. It is a daunting prospect for even the most progressive of oil companies.

Several problems in UV is commonly related to the control system of the vehicle as its application in real life is unpredictable due to changes and effects on or by the vehicle. Throughout this thesis, it will be focus on developing Remotely Operated Underwater Vehicle (ROV), design and apply control system to test the actual behavior of the vehicle. Method used to test the vehicle was by autonomous control, where image processing was applied to observe the vehicle movements. Two types of test was conducted to observe the surge and yaw behavior, therefore overshoot percentage was concluded and compared with simulation. With the design of control system actual behavior was observable and able to be compared with simulation.

This book was released on 2016 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Small scale unmanned underwater vehicles provide an opportunity to safely and efficiently complete tasks such as boat hull inspection and subsea development survey. These Remotely Operated Vehicles (ROVs) can be made more efficient if navigating underwater autonomously. This requires the development of highly accurate navigation and control algorithms, which, in turn, require a high-fidelity dynamic model of the vehicle based on first principles and validated by empirical data. In this thesis, a simulation of a dynamics model for a commercially available ROV is developed. Empirical data from open-loop testing is used to generate a second-order transfer function using system identification to validate the simulation model. The transient response characteristics of the experimentally generated transfer function are then utilized to fine-tune the physical parameters in the simulation model. Finally, autopilot systems are designed using classical control theory to enable autonomous control over the attitudes and depth of the underwater vehicle.
