ROV means "remotely operated vehicle". They are easy to use underwater robots that scientists and military use to do research and exploration. they move by using a series of propellers, and are connected to the surface with an "umbilical" cable. The cable carries power and control signals to the vehicle and video/ other sensory data back to the operators.
What Parts are there to an ROV?
ROVs move by utilizing different subsystems that include motors, tools, sensors, power, and more. They can move vertically or horizontally, which allows them to potentially maneuver tight spaces that divers cannot reach. They can sense different things and even collect samples, delivering signals back to the ship that remotely controls them. ROVs usually communicate wirelessly, sending signals back to humans. Most of the time, they have cameras that display what is in the ocean to the controller so that maneuverability is easier.

What are some examples of ROV's?
One examples of an ROV is Hercules it was built for the Institute For Exploration (IFE). Hercules was designed to study and recover artifacts from shipwrecks but also studies the biology and and geology in the deep sea. Hercules is has many special features that allow it to accomplish tasks to depths of 4,000 meters. Hercules carries many cameras and acoustic sensors that are used to gather video and other data during each dive.
