  • AUVSI launches unmanned maritime systems advocacy committee

    The Association for Unmanned Vehicle Systems International (AUVSI) has formed an Unmanned Maritime Systems (UMS) Advocacy Committee to focus on the development of policy positions to support the advancement of the industry.

    “Unmanned maritime systems allow military and commercial operators alike to go farther and deeper than ever before,” said Brian Wynne, president and CEO of AUVSI. “The input provided by the UMS Advocacy Committee will help us speak with a unified voice and enable all our members to advocate for the growth of the industry.”

    The UMS Advocacy Committee will be chaired by Thomas Reynolds, vice president of business development for Hydroid Inc./Kongsberg Maritime. Reynolds, who leads all Kongsberg Maritime business with the U.S. government, previously served as a commissioned officer in the U.S. Navy, where he served as commander of the Explosive Ordinance Disposal Task Group, U.S. Fifth Fleet, among other roles.

    Reynolds holds a bachelor of science degree from the U.S. Naval Academy and an executive master of business administration from Benedictine College.

    Wayne Prender, vice president for Applied Technology and Advance Programs at Textron Systems, will be the committee’s vice chair. In his role at Textron, Prender is responsible for engineering development programs, advancing areas such as the Common Unmanned Surface Vehicle and Cased-Telescoped Weapons and Ammunition, as well as emerging capabilities and development programs.

    Prender is a former commissioned officer in the U.S. Army, where he was deployed to Iraq and awarded the Bronze Star. He holds a bachelor’s degree in mechanical engineering from St. Louis University, a master’s degree in technology management and a master of business administration from the University of Maryland University College.

    The committee also includes representatives from BAE Systems, L3 Technologies, Leidos, Lockheed Martin, Northrop Grumman and Seaborn Defense.

    The UMS Advocacy Committee formalized a set of policy priorities to help guide the committee’s legislative and regulatory actions. The priorities state that the committee shall:

    • Establish the UMS Advocacy Committee as the preeminent industry voice influencing acquisition and regulatory policies and processes.
    • Facilitate the growth of UMS through active engagement with the government and commercial sectors.
    • Collaborate with ship owners, operators, shipyards, ports, federal maritime agencies, technology developers, classification societies and academia to further integrate advanced automation for maritime platforms into the domestic market.
    • Develop the future of the UMS workforce through technology-focused education.

  • Researchers to Test Water Drone for Bridge Inspections

    A research team at Florida Atlantic University’s (FAU) College of Engineering and Computer Science has received a $187,000 grant from the Florida Department of Transportation (FDOT) to develop autonomous waterborne vehicles that can assist in bridge inspections.

    Although the technology is still in the early stages of development, the long-term aim is that the unmanned surface vehicles (USVs) could be used by the agency to make bridge inspectors’ work safer and more efficient, according to GovTech.com. FDOT currently uses a variety of methods and equipment to inspect and test the sections of the state’s 11,451 bridges that are above water level. However, the only method that can be used to check the sub-surface areas is divers, who search for cracks, erosion, damage and defects that might impact on a bridge’s safety. A high percentage of Florida’s bridges are in corrosive salt water, and divers frequently experience problems with low visibility from silt, sediment, debris and algae, weed or other plant matter.

    The team from FAU’s Department of Ocean and Mechanical Engineering have experience in USV research, and won second place at the eighth annual International RoboBoat Competition in Virginia Beach, Va., according to GovTech.com.

    Two months into a 12-month project, the team has upgraded a watercraft used for past research projects with a new propulsion system that allows the craft to maintain its position and heading during a bridge scan. The next phase of research will be to equip the craft with an acoustic scanning system that functions in a similar manner to a LiDAR (Light Detection and Ranging) system. By installing the scanner on a mount that can tilt and pan, researchers expect to obtain 3D models of the parts of the bridge that are below the water.

    The current vessel is equipped with an automatic control system that uses GPS and a compass to direct the craft toward programmed waypoints, and can keep it steady in a variable current, allowing scanning to take place. Once the acoustic scanner is equipped in September, the team will begin testing the craft’s scanning capabilities on three bridges that have been recommended by FDOT for their diverse representation of the state’s bridge environments.

    “These sorts of technologies aren’t really meant to replace wholesale divers and so forth,” the FAU project’s principal investigator, Karl von Ellenrieder, told GovTech.com. “It’s to make their jobs easier, and it’s another tool that can help them do their jobs better. The way I view it is, you would take a vehicle like this and it would allow you to more rapidly scan bridges, and then when you detect a problem, send out a diver to verify the problem through testing. If you’re going to send divers out into strong currents with nasty snakes and stuff, it’s better to have a good sense there’s a problem before you do that.”
