INESC TEC - Instituto de Engenharia de Sistemas e Computadores, Tecnologia e Ciência is a private non-profit research institution, dedicated to scientific research and technological development, technology transfer, advanced consulting and training, and pre-incubation of new technology-based companies. INESC TEC has a multifaceted team located in 3 cities, 6 sites and 199 laboratories. Comprising more than 800 integrated researchers, more than 350 with PhD, from 25 nationalities. As part of its mission to develop science-based knowledge with societal impact, INESC TEC relies on interdisciplinary research teams organized to address societal challenges or application markets with transnational relevance. This internal arrangement with market orientation is designated as TEC4. INESC TEC’s TEC4SEA develops technological solutions to overcome the deep-sea challenges and empower the Sea Economy through sustainable approaches to explore and exploit living and non-living ocean resources. By ensuring an advanced platform for tests, research development, and interdisciplinary collaboration around sea-related topics through its TEC4Sea, INESC TEC has turned into a key stakeholder in designing and implementing national strategic infrastructures roadmaps for the Sea Economy. Contributing to this mission is INESC TEC’s Centre for Robotics and Autonomous Systems (CRAS). CRAS shows an excellent scientific track record and vast experience in underwater technologies, geo-robotics for complex environments, research projects, advanced technology development for the sea, its operation and technology transfer. CRAS works in 6 main areas of research: (i) autonomous navigation; (ii) long-term deployments; (iii) sensing, mapping, and intervention; (iv) multiple platform operations; (v) space-earth and space-water interaction and validation using innovative robotic technologies; (vi) exploration of underwater geological resources.
