New autonomous technologies will revolutionise mine clearance capability in operations close to shore through a new five-year, $15 million research and development project.
The project is part of a new partnership between Defence, Australia’s Trusted Autonomous Systems Defence Cooperative Research Centre (TAS DCRC) and Thales Australia.
Researchers will design, develop, test and evaluate various teams of micro Autonomous Underwater Vehicle swarms and Autonomous Surface Vessels, to develop new systems for underwater mine detection and clearance.
Minister for Defence Senator the Hon Linda Reynolds CSC said the project will harness Australian research and innovation capabilities in autonomous systems technologies.
“As announced in the 2020 Force Structure Plan, developing new systems for underwater mine detection and clearance are vital to protecting Australia’s maritime environment and advancing our interests,” Minister Reynolds said.
“Key technologies such as artificial intelligence, big data, connectivity and cyber security will be vital in developing the capability to autonomously undertake environmental data collection and mine countermeasures missions.
“This will help to create a safer operating environment for Australian Defence Force personnel.”
Minister for Defence Industry Melissa Price said Australian businesses will play a vital role in the TAS DCRC project.
“Our local business partners will be part of the team designing and developing a communication, simulation and training solution for the new autonomous technologies,” Minister Price said.
“We are delighted to be working with the TAS DCRC, Thales, and Australian businesses Mission Systems and INENI Realtime.
“This will help us accelerate the development and deployment of autonomous systems and solutions in the area of mine counter measures.”
Research partners include Flinders University, the University of Sydney, the University of Technology Sydney and Western Sydney University who will design, develop, test and evaluate various platforms.

Australia experimenta con drones submarinos dragaminas

Mine-hunting robots get smart
Whether providing a bird’s eye view of the battlefield or searching the ocean for mines, it’s well known robotic systems are ideally suited to dull, dirty and dangerous jobs.
The operator of an uninhabited aerial vehicle can remotely control a drone using radio or satellite communications.
However, communicating through water is more difficult, driving a need to incorporate a greater degree of autonomy in uninhabited underwater vehicles (UUVs).
Defence is experimenting with deploying UUVs to undertake mine countermeasures operations. Hunting for naval mines is obviously dangerous work, and the task of interpreting vast amounts of sonar imagery is monotonous and tiring for humans.
There are a range of technological solutions that can be used to seek out mines in the ocean, but Navy primarily relies on sonar.
As it moves through the water, a sonar device sends out pulses of sound and listen for echoes to bounce back. From this data, sonar produces acoustically generated images that should reveal any mines that might be lurking on the seabed.
Defence scientist Dr Phil Chapple has developed software that processes sonar imagery automatically detecting any objects of interest.
Known as SonarDetect, the software can be used to carry out post-mission analysis, including processing data all at once after it has been collected. But the software can also work in real time as a sonar-equipped UUV moves around the ocean.
“These robotic vehicles are normally programmed to follow certain fixed paths,” Dr Chapple said.
“They will cover an area of the seabed and go backwards and forwards to cover an area and provide images of all of the seabed.
“Those images are sent back for analysis later by the naval operator but we are trying to make that more autonomous so vehicles can respond immediately if they see something of interest.
“To do that, you have to get a good detection rate and a low false-alarm rate and that’s the challenge. If they respond to every rock on the seabed, or every fish, you’ll never get anywhere.”
Once it detects something, the vehicle might pause its predetermined search pattern to take a closer look at the object, capturing images from different angles to help identification.
The UUV might return to the surface and alert the operator of what it has found, and to await instructions.
“The software is replicating what a human would do, but a trained operator could generally do better,” Dr Chapple said.
“Humans have an ability to recognise certain objects and they know what is likely to be in certain places, so there’s a whole lot of contextual understanding that a human has which is difficult to program.”
Dr Chapple said human operators were prone to getting tired and could be distracted by other tasks.
“They start off being quite good at processing data but after a while they get fatigued and they miss things, whereas the software will just keep going,” he said.
“The software alerts the human to look at certain objects and make a decision, so it’s still a teaming between what the both can do.”
Dr Chapple said robotic vehicles were not intended to replace naval personnel but envisaged UUVs being deployed as part of a team to enhance Navy’s mine countermeasures capability.
“We’re trying to build in autonomy because it will enhance the ability of the naval operator to conduct a mission,” he said.
“If they can send out robotic vehicles, trust what they’re going to do and rely on them to come back safely then that will be a force multiplier going forward.”

La humillación de la Armada de Ucrania continúa
VIDEO: El dragaminas "Chersasky" rechaza intento de abordaje ruso
De acuerdo con lo que informó el marinero especialista torpedero Alexander Gutnik a Pravda de Ucrania, equipos de fuerzas especiales se aproximaron al barco a bordo de lanchas rápidas, pero fueron repelidos con el uso de granadas aturdidoras que los marinos ucranianos arrojaron al agua. Ante el fracaso de la operación, el mando ruso dispuso el envío del buque "Kirodograd" (ahora bajo bandera rusa), para que bloquee los movimientos del "Cherkasy", que actualmente se encuentra en medio del lago.
Hoy se dio a conocer un video captado por uno de los tripulantes del dragaminas, en el que puede verse las condiciones en que deben operar y la cercanía de los buques de guerra rusos.
Cabe recordar que el "Cherkasy" fue el único barco de la Armada de Ucrania que intentó romper el bloqueo impuesto sobre el puerto del Lago Donuzlav, tratando de desplazar a una de las embarcaciones hundidas ex-profeso por los rusos en el canal de acceso. También es uno de las naves ucranianas que más intentos de abordaje ha rechazado en la última semana.

Buque de guerra holandés realiza desminado del mar cerca de Misrata
Desde ayer, al buque dragaminas holandés Hr. Ms. Haarlem se encuentra recorriendo las aguas vecinas al puerto de Misrata,tratando de localizar las trampas explosivas sembradas por las tropas de Gadafi para bloquear la única entrada de auxilio a la ciudad sitiada.
El pasado 29 de abril, una fragata francesa descubrió a un grupo de embarcaciones depositando minas marinas en la zona, logrando destruir dos de esos artefactos, mientras que restaba localizar e inutilizar por lo menos a una mina más.
Por ese motivo se dispuso que el Haarlem realizara un rastrillaje en las aguas vecinas al puerto de Misrata, con el fin de garantizar un corredor seguro para las numerosas embarcaciones que arriban y parten mismo, ya sea transportando ayuda o evacuando a heridos y refugiados de esa ciudad que lleva más de dos meses sitiada por las fuerzas de Gadafi.
