An “ROV” is a remotely operated vehicle that is an unoccupied robot that is connected to a ship by a series of cables underwater. The cables can transmit command and control signals between the operator and the ROV, allowing to control navigation of the ROV. An “AUV” (autonomous underwater vehicle) is designed to complete similar tasks to an ROV, but an ROV is attached to an operator on a ship, whereas an AUV is not.
Major Parts of an ROV:
- Vehicle
- Tools and sensors
- Control/Display console(s)
- Electrical power distribution
- Umbilical and tether cables
- Handling system
- How do they move?
Electro-hydraulic or Electric are the classifications for the propulsion that moves the ROV. They are beneficial because they require minimal energy and make little noise in order to not disturb wildlife. The location of the thruster is also very essential. Vertical thrusters drive the ROV up and down.
- How do they "sense" the world?
An ROV is equipped with a mechanical arm that is used for moving around objects and placing objects. It also has a high definition camera that is able to capture images of parts of the ocean. Advanced sensors are attached to the ROV in order to map the seafloor and take samples of organisms on the seafloor.
- How do we communicate with the ROV while it is underwater?
We will have a long wire that connects our control unit to the ROV. Our control unit will include various switches that operate the three motors that are mounted to the ROV. Most ROVs are equipped with at least a still camera, video camera, and lights, meaning that they can transmit images and video back to the ship. Additional equipment, such as a manipulator or cutting arm, water samplers, and instruments that measure parameters like water clarity and temperature, may also be added to vehicles to allow for sample collection.
