Abstract
The remotely operated vehicle (ROV) has been widely developed for many years serving various purposes and tasks. ROV mostly used in a marine industry and scientific research. ROV is one type of submersibles that is tethered to a surface host and must be able to surface and submerge within its operational depth. There are many performance measures involve in an ROV system. One characteristic that defines a good ROV is its stability. This dissertation reports the design and development of the vehicle and the propulsion system of a new remotely operated vehicle (ROV) under the Final Year Project thesis writing in Universiti Sains Malaysia. The main issues here concern on directional drag minimization, stability, optimized thruster positioning, symmetry and layout of ROV components. This design is aimed at optimizing ROV performance for a set of different operational scenarios.
Four vital subsystems such as vehicle, pump driver, joystick controller and lighting system have been successfully developed by time. The vehicle has been tested for various aspects such as stability and propulsion system. Leak problem has been the major problem during completing the test but the problem has been solved through multiple tests to find the leak area. Meanwhile the propulsion system is yet to be fully tested due to time constraint. Power issues such as currents which are supposed to be supplied at 10 ampere for each pump are not available due to battery flatness. Instead of using battery, power supply is used which it could only provide the maximum of 5 ampere nominal currents. Therefore this phenomenon resulted in weak thrusting forces which also contributed to slower motion. To this end the complete ROV system is yet to achieve but vital subsystems are available and ready to be integrated and complied with requirement of thesis objectives.
