Abstract

In the world of underwater vehicle industries, thruster are important to control the direction, the depth and the speed of the Remotely Operated Vehicle (ROV).There are many types of ROV design and structure, and it all comes with different size of thruster design. The problems that occur in the underwater where require a person to dive in the water at a certain depth in a long time are difficult and endanger the divers’ safety. Thus, an auto depth control system is prepared to implemented into the previous UTeM ROV (UTeRG-ROV). This project focuses on the operation principle on which the UTeRG-ROV can submerge and emerge using thrusters and help the UTeRG-ROV to maintain at the specified depth. This project is to develop a prototype of thruster that has the auto depth control which attached to the UTeRG-ROV to demonstrate the basic operation of auto depth control as well as it operation in the water. The thrusters have its own saturation point which means it has a maximum depth that the thrusters can submerge the UTeRG-ROV. Therefore, ballast tank is used to submerge deeper. The maximum depth the UTeRG-ROV can submerge by using thruster system is 0.7m. The thruster model will thrust and submerge until it reaches a set point which is 0.5m and maintain at the set point depth. The depth was based on pressure sensor measurement.
