Developing an underwater glider for educational purposes
2013 IEEE International Conference on Robotics and Automation, 2013Buoyancy-driven underwater gliders (UGs) have proven to be quite effective for long-range, long-term oceanographic sampling. However, current off-the-shelf UGs are large, heavy, expensive, and difficult to modify, both in hardware and software, which prevents their frequent use for lake observations and limits researchers' ability to perform multi ...

Buoyancy engine developed for underwater gliders
Advanced Robotics, 2016A buoyancy engine with a swashplate-type axial piston pump was developed. Its oil extrusion and drawing properties under high hydraulic pressure were evaluated. This buoyancy engine is now installed in an underwater glider that will achieve long-term monitoring of ocean environments up to 2100 m depth in a designated area with lower operational costs ...

Underwater gliders control strategies: A review
2015 10th Asian Control Conference (ASCC), 2015Underwater Gliders (UGs) are a type of Autonomous Underwater Vehicle (AUV) that uses buoyancy engines, an energy efficient locomotion, primarily for oceanography. In this paper, control strategies for existing underwater gliders are reviewed. A total of 50 papers indexed by Scopus with keywords control and underwater gliders were reviewed from 1989 to ...

This chapter discusses the characteristics, design considerations, and performance of autonomous underwater (UW ) gliders. These buoyancy-propelled, winged vehicles can be categorized as: (1) profiling gliders that traverse in bobbing trajectories to collect vertical profiles of ocean properties and (2) cross-country gliders designed for point-to-point

Negotiation of the Multi-underwater Glider System
First International Conference on Innovative Computing, Information and Control - Volume I (ICICIC'06), 2006This paper presents the theoretical development of the negotiation of a multi-underwater glider problem, where glider is called agent. Negotiation is a key point in multi-agent (multi-underwater glider) system, which aims to accomplish cooperation and coordination.

Lagrangian Modelling of an Underwater Wave Glider
Ship Technology Research, 2012AbstractThis paper introduces a control-oriented modelling approach for a hybrid autonomous underwater vehicle, the Underwater Wave Glider. The vehicle can accomplish both surface and underwater tasks by changing its shape: it can operate as a wave glider at the sea surface, exploiting wave and solar energy to recharge the onboard batteries, and switch

Task allocation approach for underwater gliders in complex underwater missions
2021 4th IEEE International Conference on Industrial Cyber-Physical Systems (ICPS), 2021This paper proposes an Genetic Algorithm(GA)-based task allocation approach for heterogenous underwater gliders in complex underwater search and detection missions. First of all, the mathematical model of the underwater glider task allocation problem is formulated while considering motion characteristics of underwater gliders and different task ...

A maneuverable, pneumatic underwater glider
2012 Oceans, 2012A coastal (100 meter depth) underwater glider has been developed to serve as a platform for testing advanced perception, planning, and control algorithms to improve glider efficiency and performance. The glider's buoyancy engine is pneumatically powered, and capable of generating large changes in buoyancy.

Stability and performance of underwater gliders
2012 Oceans, 2012Underwater gliders are efficient mobile sensor platforms that can be deployed for months at a time, traveling thousands of kilometers. As with any vehicle, different applications impose different mission requirements which impact vehicle design. In this paper, we consider a conventional glider configuration and investigate the relationship between ...

Routing strategies for underwater gliders
Deep Sea Research Part II: Topical Studies in Oceanography, 2009Abstract Gliders are autonomous underwater vehicles that achieve long operating range by moving at speeds comparable to those of, or slower than, typical ocean currents. This paper addresses routing gliders to rapidly reach a specified waypoint or to maximize the ability to map a measured field, both in the presence of significant currents. For rapid
