Traditionally unmanned undersea vehicles (UUVs) have been large, complex and expensive. Development of UUVs has been driven by defense and commercial requirements. This has allowed for extensive research and development budgets and long development cycles. This paper briefly discuses these historic drivers and how this situation has changed. It focuses on a new compact affordable UUV. In 2015, several...
The Wave Glider® is a unique wave and solar energy powered Unmanned Surface Vehicle (USV). Development of this technology began in 2005 and in 2007 the company Liquid Robotics was created to bring this product to market. In the ten years since the company was founded the Wave Glider and the entire field of USVs has evolved significantly. Lessons learned revolve around three primary themes: technology,...
The National Oceanic and Atmospheric Administration (NOAA) employs many technologies in its diverse missions. NOAA challenges include monitoring the atmosphere and predicting the weather, charting the Nation's waterways, protecting marine sanctuaries, managing fisheries resources and exploring and understanding our ocean planet. In an era of strained budgets and declining availability of conventional...
Unmanned Maritime Vehicles (UMVs) have been under development, especially with US Navy research funds, for decades. However, meaningful advances in the commercial sector have only been seen in the past 20 years. In 1997 Bluefin Robotics was formed out of the Massachusetts Institute of Technology Sea Grant College Program Autonomous Underwater Vehicle Lab. Since then many other companies have developed...
The Wave Glider is a unique wave and solar energy powered Unmanned Surface Vessel (USV). Its two-part design makes it well suited for towing instruments at depth. Deploying a towed payload from a Wave Glider results in a three body, two tether, configuration. Technical considerations for towing payloads include: Drag, Mass, Buoyancy, Power and Communications. These challenges can be managed through...
Unmanned “gliders” have demonstrated long endurance operations and are the platform of choice for broad scale meteorology and oceanography (METOC). With buoyancy engines, gliders can operate for months and have demonstrated success with common oceanographic sensors. Likewise low frequency acoustics have been used for basin scale tomography for many years. Together these technologies present a comprehensive...
To celebrate the 40th Anniversary of the Oceanic Engineering Society (OES) at the MTS/IEEE OCEANS 2008 Conference in Quebec City a series of review papers were requested from OES technical committee chairs. In response to that request this paper provides a review of the field of unmanned surface vehicles (USVs) and autonomous surface craft (ASCs). The paper discusses the enabling technologies that...
