Review of low cost micro remotely operated underwater vehicle

This paper investigates and reviews the modeling and designs of ROVs, as well as their control systems, and attempts to draw on their limitations in terms of structure, durability, and ease of handling while keeping the economic factor in mind. The Remotely Operated underwater Vehicles (ROVs) are specially designed robotic systems that can be deployed on or below the water's surface to perform various studies and tasks in treacherous offshore circumstances. These ROVs are equipped with different devices and sensors, such as camera, propulsion system, sonar devices, temperature measurement units, counter balance, ballistics, and sensors, to analyze the data collected. The purpose of this article is to analyze the evolution of various available ROVs and the control strategies used in their design, as well as their merits and demerits. It also identifies the primary issues associated with ROVs.
