AUV is the acronym in English for autonomous underwater vehicle, in other words, it is an underwater vehicle capable of carrying out missions in a fully autonomous way without the need to maintain physical contact with the surface, as it has all the energy necessary to carry out the mission and beyond Furthermore, it is pre-programmed and has an electronic system to guide you through the mission. This type of vehicle is equipped with several sensors that help to adjust depth, speed, direction and the location of possible obstacles during a mission. Additional sensors can equip an AUV, enabling it to be able to carry out oceanographic research missions, underwater monitoring as well as for shipwreck detection, archaeological site mapping and exploration in the oil and gas sector. At the end of the mission, the vehicle returns to the surface and it is possible to make a connection for the transmission of data collected by the vehicle.

TERRA is the first competition team at UFSC - Joinville campus to dedicate itself to the research, analysis and construction of an autonomous submarine vehicle (AUV). Made official by the institution in May 2019, the team includes members from the most varied courses at UFSC - Joinville.

A little more about AUV's

Advantages

Unlike an ROV that is a remotely operated vehicle, the AUV, as it does not need a tether (cable for power transmission and data transmission), enables missions to be carried out in difficult-to-access locations, including under ice in polar regions. And because it's autonomous, there's no need for a large support ship during missions.

Disadvantages

Because it needs a very sophisticated electronic system to mainly avoid accidents during missions, this type of equipment has a very high cost. In addition, there are limitations in missions regarding battery autonomy, that is, the pre-programmed mission must take into account that the vehicle is able to return to the surface so that the batteries can be recharged. And because it operates underwater and without a theter, it is very difficult to transmit images in real time, as the properties of water limit data transmission. In this sense, there is also a high risk of losing the vehicle if it has a collision, gets stuck in something or if its navigation accuracy fails.

Trivia

The most common shape of an AUV is a cylindrical body similar to a missile, such as the EcoMapper. However, there are AUVs with the most diverse formats, for example the Girona 500 and the Artemis that have a completely different design.
