==Construction==
Work-class ROVs are built with a large flotation pack on top of an aluminium [[chassis]] to provide the necessary [[buoyancy]] to perform a variety of tasks. The sophistication of construction of the aluminum frame varies depending on the manufacturer's design. [[Syntactic foam]] is often used for the flotation material. A tooling skid may be fitted at the bottom of the system to accommodate a variety of sensors or tooling packages. By placing the light components on the top and the heavy components on the bottom, the overall system has a large separation between the center of buoyancy and the [[center of gravity]]: this provides stability and the stiffness to do work underwater. [[Underwater thruster|Thrusters]] are placed between center of buoyancy and center of gravity to maintain the attitude stability of the robot in maneuvers. Various thruster configurations and control algorithms can be used to give appropriate positional and attitude control during the operations, particularly in high current waters. Thrusters are usually in a balanced vector configuration to provide the most precise control possible.

Electrical components can be in oil-filled water tight compartments or one-atmosphere compartments to protect them from corrosion in seawater and being crushed by the extreme pressure exerted on the ROV while working deep. The ROV will be fitted with thrusters,  [[camera]]s, lights, tether, a frame, and pilot controls to perform basic work.<ref>{{Cite web |title=What is an Underwater ROV? |url=https://bluerobotics.com/learn/what-is-an-rov/ |access-date=2024-01-12 |website=Blue Robotics |language=en-US}}</ref> Additional sensors, such as [[manipulator (device)|manipulators]] and sonar, can be fitted as needed for specific tasks.<ref>{{Cite web |date=2021-10-08 |title=What Are Underwater ROVs & How Are They Used? |url=https://reachrobotics.com/blog/what-is-an-underwater-rov/ |access-date=2023-03-29 |website=reachrobotics.com |language=en-AU}}</ref> It is common to find ROVs with two robotic arms; each manipulator may have a different gripping jaw. The cameras may also be guarded for protection against collisions.

The majority of the work-class ROVs are built as described above; however, this is not the only style in ROV building method. Smaller ROVs can have very different designs, each appropriate to its intended task. Larger ROVs are commonly deployed and operated from vessels, so the ROV may have landing skids for retrieval to the deck.
