An Autonomous Underwater Vehicle (AUV) is a robotic device that is driven through the water by a propulsion system, controlled and piloted by an onboard computer, and maneuverable in three dimensions. This level of control, under most environmental conditions, permits the vehicle to follow precise preprogrammed trajectories wherever and whenever required. Sensors on board the AUV sample the ocean as the AUV moves through it, providing the ability to make both spatial and time series measurements. Sensor data collected by an AUV is automatically geospatially and temporally referenced and normally of superior quality. Multiple vehicle surveys increase productivity, can insure adequate temporal and spatial sampling, and provide a means of investigating the coherence of the ocean in time and space.
Autonomous underwater vehicle fall in to mobile robotics sector and are of brilliant importance to the present world military and commercial requirements. The need to find cutting edge in military research induces the invention of AUVs. This paper gives a glimpse on autonomous underwater vehicles and its applications.
An autonomous underwater vehicle (AUV) is a robot which travels underwater without requiring input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) ? controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications AUVs more often referred to simply as unmanned undersea vehicles (UUVs).

CLASSIFICATION:
Mobile robots may be classified by the environment in which they travel:

  • Land or home robots. (humanoid, or resembling animals or insects).
  • Aerial robots are usually referred to as unmanned aerial vehicles (UAVs)
  • Underwater robots are usually called autonomous underwater vehicles (AUVs)
  • Polar robots, designed to navigate icy, crevasse filled environments
