The Wave Glider: A New Concept for Deploying Ocean Instrumentation

IEEE Instrumentation & Measurement Magazine, 2010
Wave Glider is a combination sea-surface and underwater vehicle comprised of a submerged "glider" that is attached to a surface float via a flexible tether. Fig. 1 shows the Wave Glider. It is propelled by the conversion of ocean wave energy into forward thrust, independent of wave direction.

Wave Glider–Enhanced Vertical Seafloor Geodesy

Journal of Atmospheric and Oceanic Technology, 2020
AbstractWe have developed a low-cost approach for accurately measuring short-term vertical motions of the seafloor and maintaining a continuous long-term record of seafloor pressure without the requirement for costly ship time. We equipped the University of Hawai‘i Liquid Robotics Wave Glider with an integrated acoustic telemetry package, a dual ...

Estimation of wave glider dynamics for precise positioning

OCEANS'11 MTS/IEEE KONA, 2011
The wave glider is a new autonomous surface platform with unique capabilities for persistent observation in a variety of marine environments. The applications of this novel technology continue to expand; some of the potential oceano-graphic applications will require precise positioning and navigation beyond the platforms current capabilities.

Energy Conversion Efficiency of Wave Gliders

Membrane Technology
Wave gliders are a new type of ocean observation platform that can gain forward power by receiving and converting wave energy. The ability of wave gliders to turn waves determines the speed, maneuverability, and precision of wave gliders’ navigation control in various sea conditions.

Evolved Gliders and Waves on a Geodesic Grid

2016
Cellular automata (CA) are typically modeled on 1D, 2D, or 3D grids. To avoid boundary artifacts, it is common to create periodic boundary conditions so that opposing boundarieswrap around. In the case of a 2D cellular automaton, this periodic boundary creates the topological equivalent of a torus.

Course Control of Unmanned Wave Glider With Heading Information Fusion

IEEE Transactions on Industrial Electronics, 2019
The unmanned wave glider (UWG) is a new kind of wave-powered unmanned marine vehicle for persistent marine environment monitoring. However, the course control of UWG is unusual due to the special multijoint structure and special operating principle. Control methods for single body marine vehicles cannot guarantee the control performance of UWG. In this

Tracking tagged fish using a wave glider

OCEANS 2015 - MTS/IEEE Washington, 2015
In this paper, we show how using a Liquid Robotics Wave Glider can allow for a mobile and comprehensive solution for detecting tagged animals in real time and characterizing their environment. We will compare the Wave Glider based solution to more traditional buoy and boat based solutions and note the unique advantages of this novel, new technology ...
