AUV Barabas

The autonomous underwater robot or AUV Barabas of VLIZ is a Gavia from Teledyne, operational till depths of 1000 meters. The AUV can be deployed in both national and international waters. The robot can be launched from a dock, a small RIB or from a large research vessel.

What is an AUV?

An autonomous underwater vehicle (AUV) is a robotic vehicle that can perform tasks under water without direct control from an operator. An AUV typically has the ability to steer and make decisions itself while underwater. This makes the AUV a powerful tool for exploring the ocean depths where it can be hard for scientists to reach. AUVs have been widely used in various industries, from construction to search and rescue.

Why use an AUV?

The AUV Barabas of VLIZ is a Gavia from Teledyne Marine allows for multiple configurations which allows it to do a number of tasks. These could include:

  • The surveying of wrecks and underwater obstacles close to the seafloor in high detail.
  • Investigate and measure properties of the ocean water column.
  • Compliment other research, like fill the gap between broad ship surveys and hyper-focussed ROV inspection.
