Ocean Operational Experience with the Autosub - 1 Autonomous Underwater Vehicle
نویسندگان
چکیده
The Autosub-la autonomous underwater vehicle (AUV) designed, built and operated by the Southampton Oceanography Centre is a medium endurance, multipurpose sensor platform designed for marine science studies of the upper ocean. With a specified range of 250 km, operating at 3.8 kt, and a diving depth capability of 500 m the vehicle has completed 179 engineering and science missions in UK coastal waters, off the east coast of Florida and off Bermuda. This paper focuses on three key areas particularly important to AUVs operating on long missions in the deep or open ocean: the predictability of the primary cell energy supply, particularly its predictability; buoyancy changes in a vehicle without active buoyancy control and scientific sensor performance the raison d’2tre for the vehicle. We draw upon the methods, observations and results from the 1998 Autonomous Vehicle Validation Experiment (AVVEX) when Autosub1 a operated off Bermuda in August-September 1998.

On the Reliability of the Autosub Autonomous Underwater Vehicle
As autonomous underwater vehicles (AUVs) enter operational service an assessment of their reliability is timely. Using the Autosub AUV as an example, several design issues affecting reliability are discussed, followed by an analysis of recorded faults. Perhaps contrary to expectations, failures rarely involved the autonomous nature of the vehicle. Rather, faults were typical of those that occur...

In this paper, kinematic and dynamic equations of a 6-DOF (Degrees Of Freedom) autonomous underwater vehicle (6-DOF AUV) are introduced and described completely. By developing the nonsingular terminal sliding mode control method, three separate groups of control inputs are proposed for the autonomous underwater vehicle subjected to uncertainties including parametric uncertainties, unmodeled dyn...
متن کاملDevelopment of a Simple Navigation System for the Autosub Autonomous Underwater Vehicle
Autosub is a project funded by the Natural Environment Research Council in the UK, with the aim of developing unmanned autonomous underwater vehicles to carry out long range scientific missions in the deep ocean. The navigation system is critical to the survival of the vehicle, and so it is important that appropriate software engineering methods are used. Structured analysis and design methods ...
متن کاملAn Approach for Operation Depth Reduction of an Underwater Glider Propelled by Ocean Thermal Energy
The underwater Gliders are a kind of autonomous vehicles that have a special role in ocean surveys which demand continuous monitoring and long endurance. Because of low energy consumption and long endurance, these vehicles are favorite for these missions. Among this, a type of gliders can harvest ocean thermal energy, causing significant endurance increase. These vehicles need at least 680 mete...
متن کاملIdentification of an Autonomous Underwater Vehicle Dynamic Using Extended Kalman Filter with ARMA Noise Model
In the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. Since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. In this study, hydrodynamic coefficients of an autonomous un...
