An important step was taken in the continuation of the American educational project "Educational Passages", which involved a collaboration between Instituto Superior Técnico the, Institute for Systems and Robotics in Lisbon and the Escola Azul programme, implemented by DGPM - Directorate General for Maritime Policy, with additional support from the company Transinsular. The project aims to launch small, unmanned boats equipped with GPS into the ocean, like 21st-century "messages in a bottle," allowing their paths to be followed as they cross the sea.
