    Remotely operated underwater vehicles (ROVs) are remote control underwater robots driven by an individual on the surface. These robots are tethered by a series of wires that send signals between the operator and the ROV. All ROVs are equipped with a video camera, propulsion system, and lights. Other equipment is added depending on the specifications required. These include a manipulator arm, water sampler, instruments that measure clarity, light penetration, temperature, and depth. Remotely operated underwater vehicles or ROVs are underwater robots that are used in science, entertainment, military and offshore oil industries. Their main function is to interact with the environment under the water in various ways. This project presents design and development of a small unman submarine. The underwater vehicle is designed to work instead of human beings because there is a risk to use human beings to explore in a difficult to reach and hazardous areas. Human explorer performance under water are limited. Thus, a dedicated tool or device such as a Remotely Operated Underwater Vehicle (ROV) is required in helping human to perform these research activities. The vehicle equips with powerful underwater probe sensors to collect underwater data, dc brushless motor for controlling direction, a set of LED lights for illumination as well as real time camera monitoring. It transmits video data and perform an automated drive. The data is sent via underwater cable to computers base station on the coast. The tilt control, achieve automated pitch stability and perform underwater observation through a video camera where surge control is by Bluetooth electric, an android application operated via bluetooth. The base station can control the direction of the underwater probes in the desired direction easily and more accurately. The tools used in the developing process is processing program for GUI and microcontroller (Arduino) for reading and controlling all sensors data such as accelerometer, gyro meter and motor speed control in order to keep the vehicle stabilizer movement.
