- Development of an Unmanned Capsule for large-scale maritime search and rescuePublication . Matos, Aníbal; Silva, Eduardo; Cruz, Nuno; Alves, José Carlos; Almeida, Duarte Rafael; Pinto, Miguel Armando; Martins, Alfredo; Almeida, José Miguel; Machado, Diogo CabralThis paper describes the development and testing of a robotic capsule for search and rescue operations at sea. This capsule is able to operate autonomously or remotely controlled, is transported and deployed by a larger USV into a determined disaster area and is used to carry a life raft and inflate it close to survivors in large-scale maritime disasters. The ultimate goal of this development is to endow search and rescue teams with tools that extend their operational capability in scenarios with adverse atmospheric or maritime conditions.
- Field experiments for marine casualty detection with autonomous surface vehiclesPublication . Martins, Alfredo; Dias, André; Almeida, José Miguel; Ferreira, Hugo Miguel; Almeida, Carlos Valente; Silva, Guilherme Amaral; Machado, Diogo Cabral; Sousa, João Ricardo; Pereira, Pedro Oliveira; Matos, Aníbal; Lobo, Vitor; Silva, EduardoIn this paper we present a set of field tests for detection of human in the water with an unmanned surface vehicle using infrared and color cameras. These experiments aimed to contribute in the development of victim target tracking and obstacle avoidance for unmanned surface vehicles operating in marine search and rescue missions. This research is integrated in the work conducted in the European FP7 research project Icarus aiming to develop robotic tools for large scale rescue operations. The tests consisted in the use of the ROAZ unmanned surface vehicle equipped with a precision GPS system for localization and both visible spectrum and IR cameras to detect the target. In the experimental setup, the test human target was deployed in the water wearing a life vest and a diver suit (thus having lower temperature signature in the body except hands and head) and was equipped with a GPS logger. Multiple target approaches were performed in order to test the system with different sun incidence relative angles. The experimental setup, detection method and preliminary results from the field trials performed in the summer of 2013 in Sesimbra, Portugal and in La Spezia, Italy are also presented in this work.
- Multiple robot operations for maritime search and rescue in euRathlon 2015 competitionPublication . Matos, Aníbal; Martins, Alfredo; Dias, André; Ferreira, Bruno; Almeida, José Miguel; Ferreira, Hugo; Amaral, Guilherme; Figueiredo, André; Almeida, Rui; Silva, FilipeThis paper presents results of the INESC TEC participation in the maritime environment (both at surface and underwater) integrated in the ICARUS team in the euRathlon 2015 robotics search and rescue competition. These relate to the marine robots from INESC TEC, surface (ROAZ USV) and underwater (MARES AUV) autonomous vehicles participation in multiple tasks such as situation assessment, underwater mapping, leak detection or victim localization. This participation was integrated in the ICARUS Team resulting of the EU funded project aimed to develop robotic tools for large scale disasters. The coordinated search and rescue missions were performed with an initial surface survey providing data for AUV mission planning and execution. A situation assessment bathymetry map, sidescan sonar imaging and location of structures, underwater leaks and victims were achieved, with the global ICARUS team (involving sea, air and land coordinated robots) participating in the final grand Challenge and achieving the second place.
- Strengthening Marine and Maritime Research and TechnologyPublication . Silva, Eduardo; Martins, Alfredo; Dias, André; Matos, Aníbal; Olivier, Augustin; Pinho, Carlos; Sá, Filipe Aranda de; Ferreira, Hugo; Silva, Hugo; Alves, José Carlos; Almeida, José Miguel; Pessoa, Luís; Ricardo, Manuel; Cruz, Nuno; Dias, Nuno; Mónica, Paulo; Jorge, Pedro; Campos, RuiINESC TEC is strongly committed to become a center of excellence in maritime technology and, in particular, deep sea technology. The STRONGMAR project aims at creating solid and productive links in the global field of marine science and technology between INESC TEC and established leading research European institutions, capable of enhancing the scientific and technological capacity of INESC TEC and linked institutions, helping raising its staff’s research profile and its recognition as a European maritime research center of excellence. The STRONGMAR project seeks complementarity to the TEC4SEA research infrastructure: on the one hand, TEC4SEA promotes the establishment of a unique infrastructure of research and technological development, and on the other, the STRONGMAR project intends to develop the scientific expertise of the research team of INESC TEC.
- TEC4SEA - A Modular Platform for Research, Test and Validation of Technologies Supporting a Sustainable Blue EconomyPublication . Mónica, Paulo; Martins, Alfredo; Olivier, Augustin; Matos, Aníbal; Almeida, JoséThis paper presents the TEC4SEA research infrastructure created in Portugal to support research, development, and validation of marine technologies. It is a multidisciplinary open platform, capable of supporting research, development, and test of marine robotics, telecommunications, and sensing technologies for monitoring and operating in the ocean environment. Due to the installed research facilities and its privileged geographic location, it allows fast access to deep sea, and can support multidisciplinary research, enabling full validation and evaluation of technological solutions designed for the ocean environment. It is a vertically integrated infrastructure, in the sense that it possesses a set of skills and resources which range from pure conceptual research to field deployment missions, with strong industrial and logistic capacities in the middle tier of prototype production. TEC4SEA is open to the entire scientific and enterprise community, with a free access policy for researchers affiliated with the research units that ensure its maintenance and sustainability. The paper describes the infrastructure in detail, and discusses associated research programs, providing a strategic vision for deep sea research initiatives, within the context of both the Portuguese National Ocean Strategy and European Strategy frameworks.
