Ocean Research Enabled by Underwater Gliders
Annual Review of Marine Science, 2016Underwater gliders are autonomous underwater vehicles that profile vertically by changing their buoyancy and use wings to move horizontally. Gliders are useful for sustained observation at relatively fine horizontal scales, especially to connect the coastal and open ocean. In this review, research topics are grouped by time and length scales.

Discrete Decentralized Supervisory Control for Underwater Glider
Sixth International Conference on Intelligent Systems Design and Applications, 2006In order to independently undertake complex missions in unstructured and unknown undersea environment, artificial intelligence techniques are needed to provide underwater glider with ability of active autonomy. Based on the RW (Ramadge & Wonham) supervisory control theory of discrete event dynamic system (DEDS), a three-level intelligence control ...

Surrogate Models for Shape Optimization of Underwater Glider
2009 International Conference on Computer Modeling and Simulation, 2009Design of experiments and surrogate models method facilitating much of today’s engineering design and optimization. In this paper we systematically compare several experimental design types and surrogate modeling techniques in terms of their capability to generate accurate approximations for the shape optimization of underwater gliders.

Design and Analysis of a Novel Underwater Glider - RoBuoy
2018 IEEE International Conference on Robotics and Automation (ICRA), 2018Underwater gliders are special class of autonomous underwater vehicles (AUVs) proven to be power efficient with better range and endurance compared to the conventional underwater robots. Most of the existing underwater gliders use ‘change of mass’ based variable buoyancy (VB) method in which the overall system architecture and construction are complex.

Research on the Hierarchical Supervisory Control of Underwater Glider
2006 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2006An underwater glider is a buoyancy-propelled and fixed-wing vehicle with attitude controlled completely by means of internal mass redistribution. In order to independently accomplish complex missions in unstructured and unknown oceanic environment, intelligent control system is needed to provide the underwater glider with the ability of active autonomy.

Mapping the underside of an iceberg with a modified underwater glider
Journal of Field Robotics, 2019AbstractIcebergs pose many challenges to offshore operations in the Arctic Ocean and sub‐arctic regions. They could damage underwater infrastructure such as pipelines, and disrupt marine transportation. The below‐water shape of an iceberg is a key factor for iceberg management in the North Atlantic Ocean because it affects the iceberg towing plans and ...

Development of an Underwater Glider with Density-Difference-Engine
2018 World Automation Congress (WAC), 2018This study details the development of an ‘underwater glider with a density-difference-engine’ for the use of oceanographic survey, monitoring the marine environment, fisheries, ocean exploration, and marine sports/leisure activities. The underwater glider presented here is unique, in that it incorporates no propulsion machinery which makes it silent ...

Bouyancy compensation analysis of an autonomous underwater glider
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011The autonomous underwater glider is propelled by changing its net buoyancy. The value of the net buoyancy is essential to the glider's movement. In this paper, a finite element method combined with theoretical calculation is utilized to calculate the deformation of the vehicle's pressure hull.
