This paper presents the Inter-Module Communication (IMC) protocol, a message-oriented protocol designed and implemented in Underwater Systems Technology Laboratory (LSTS) to build interconnected systems of vehicles, sensors human operators that are able pursue common goals cooperatively by exchanging real-time information about environment updated objectives. IMC abstracts hardware communication heterogeniety providing shared set messages can be serialized transferred over different means.
Como o tipo mais comum de acidente vascular cerebral (AVC), AVC isquêmico representa uma morbidade significativa para os sistemas saúde pública e indivíduos. A butilftalida, nesse contexto, é um componente aprovado tratamento devido aos seus efeitos protetores contra isquemia cerebral. O presente estudo revisão buscou avaliar a eficácia da terapia partir butilftalida em pacientes acometidos por (AVCi) agudo, ensaios clínicos randomizados publicados na literatura médica atual. Trata-se...
The C3I (command, control, communication and information) Neptus framework which is being developed at the Underwater Systems Technology Laboratory (USTL/LSTS) presented. a modular mixed initiative (human operators in control loop) for operation of heterogeneous teams vehicles such as autonomous remotely operated underwater, surface, land, air vehicles. composed mission vehicle planning, supervision, post-mission analysis modules are provided services across network. This paper focus mainly...
Underwater acoustic networks can be quite effective to establish communication links between autonomous underwater vehicles (AUVs) and other or control units, enabling complex vehicle applications scenarios. A communications framework support the use of sample application scenarios are described for single multi-AUV operation.
This paper describes the development of a C3I (communications, command, control and intelligence/information) infrastructure, taking place at Underwater Systems Technology Laboratory (LSTS) FEUP. Neptus framework, goal is to support coordinated operation heterogeneous teams, which include autonomous remotely operated underwater, surface, land, air vehicles people. People perform fundamental role, not only in case vehicles, but also with where mix-initiative requirement. The operational...
This paper presents the LAUV (Light Autonomous Underwater Vehicle), with special emphasis on most recent developments and discusses how enables networked operations. The is a lightweight, one-man-portable vehicle specially designed to be highly operational effective surveying tool for oceanographic, hydrographic, security inspections applications. evolving rapidly bridge gap between theory operations by enabling concepts of operation which could have only been imagined before. done state art...
Over the last decade, ocean sunfish movements have been monitored worldwide using various satellite tracking methods. This study reports near-real time monitoring of fine-scale (< 10 m) behaviour sunfish. The was conducted in southern Portugal May 2014 and involved tags underwater surface robotic vehicles to measure both contextual environment fish. A total four individuals were tracked custom-made GPS providing geolocation estimates resolution. These accurate positions further informed...
The tragic Deepwater Horizon accident in the Gulf of Mexico 2010 as well increase deepwater offshore activity have increased public interest counter-measures available for sub-surface releases hydrocarbons. To arrive at proper contingency planning, response managers urge a system instant detection and characterization accidental releases. Along these lines, this paper describes application heterogeneous robotic unmanned vehicles: autonomous underwater vehicle (AUV), surface (USV) aerial...
In April 2016, NTNU, FFI, Kongsberg Seatex, LSTS and Maritime Robotics set up an experiment to explore their capability combine the research vessel Gunnerus, AUV Hugin, UAV X8 USV Mariner in a network of heterogeneous unmanned vehicles. Communication, manoeuvring, onboard processing operational complexity are essential components such networks. To provide communication MBR broadband radio system was implemented. show capabilities proposed, scenario with seabed mapping target recognition...
The paper describes the seventh edition of Rapid Environmental Picture Atlantic exercise (REP16-Atlantic) which took place in July 2016 along coast Sesimbra and Troia, Portugal. intent was to demonstrate coordinated operations unmanned underwater, surface, air vehicles contributed by participants coming from different European institutions both research industry fields. REP-Atlantic is a yearly demonstration targeted at advancing state art networked vehicle systems through large scale...
In order to further expand the sustainability of maritime operations use autonomous vehicles has been employed at an increasing scale. This natural increase comes not only in form multiplication numbers same vehicle model, but also diversifying composition setup allow exploitation different types payloads. Moreover, this heterogeneous multi-vehicle teams allows overcoming individual limitations that one specific model might have. Nevertheless, scale and functionality causes control,...
This paper presents a report from cruise onboard the R/V Falkor oceanographic vessel Schmidt Ocean Institute.
