The MORPH project advances the novel concept of an underwater robotic system composed of a number of spatially separated mobile robot-modules, carrying distinct and yet complementary resources. Instead of being physically coupled, the modules are connected via virtual links that rely on the flow of information among them, i. e. inter-module interactions are allowed by underwater communication networks at distant and close ranges and supported by visual perception at very close range. The MORPH supra-vehicle (MSV) is thus in sharp contrast to classical monolithic vehicles or even cooperative groups of marine vehicles that operate safely away from each other. These lack the capability of mutual support and multi-sensor interaction.Without rigid links, the MSV can reconfigure itself and adapt in response to the shape of the terrain. This capability provides the foundation for efficient methods to map the underwater environment with great accuracy especially in situations that defy existing technology: namely, underwater surveys over rugged terrain and structures with full 3D complexity. This includes walls with a negative slope, where precise localization of a single vehicle is not possible.The possible applications of the MSV cover a wide range of scientific and commercial areas such as monitoring of cold water coral reefs, oil and gas pipeline inspection, or harbor and dam protection. The common characteristic of these areas is the need for operating multiple, complementary instruments at very close range to unstructured underwater terrain while accomplishing proper geo-referencing at the same time.The MORPH concept requires qualitatively new behaviors such as adaptive sensor placement for perception and navigation, as well as environmental modeling in complex environments. On site view planning will lead to a solution well beyond the operational state of the art for underwater cliff surveys and other similar missions. A final demonstration on a vertical cliff, unfeasible automatically with todays technology, will validate the efficacy of the methods developed.

The Robocademy ITN will establish a European training and research network to develop key skills and enabling technologies in underwater robotics for the scientific and economic exploration of the oceans (e.g. offshore oilfield of the future). Through the close collaboration of leading research institutes, academia, industry, and SMEs in robotics, marine technology, marine science, and offshore industry, Robocademy will provide first-class training and research opportunities for ESRs. In well-defined and well-tutored PhD research projects, the Robocademy fellows will push the state-of-the-art in the area of robust, reliable and autonomous underwater robots. Specialized scientific training modules will enable the fellows to obtain both a sound basis in robotics and an introduction to topics that are specific to their research areas. This will be complemented by a high-quality soft-skills training programme for and the opportunity to gain extensive on-site hands-on experience through secondments to maritime industry and oceanographic research institutes. Thus Robocademy will foster the formation of young professionals that are able to meet the urgent demand for highly-qualified researchers and engineers in the growing field of underwater systems and robotics. For the European industry and scientific community, such specialists are crucial gain ground against competitors from North America and Asia. For the ESRs, the Robocademy training will open up excellent career opportunities in both academia and industry.


The invention relates to an acoustic converter (101), in particular a hydrophone (103), comprising an interferometer and an associated first vibration element (151, 251), which is maintained by a support. Said interferometer comprises a light source (111), a first signal beam (113), a signal beam splitter, a first reference beam (115), a first scanning beam (117), a first measuring beam (119) and an optical sensor (141). Said light source emits the first signal beam and the first reference beam and the first measuring beam are superimposed onto the optical sensor. The first scanning beam is directed to the first vibration element and the first measuring beam causes a Doppler shift with respect to the first scanning beam based on a vibration of the first vibration element, characterized in that the first vibration element is arranged in a first liquid.


The present disclosure provides a method for clearing weapons that have been sunk in waterways using a weapon clearance appliance. The weapon clearance appliance comprises means for detachable connection to an unmanned underwater vehicle, so that the underwater vehicle is a safe distance away when the weapon is detonated. The volume of the weapon clearance appliance is chosen such that the buoyancy force which acts on the weapon clearance appliance under water compensates for the force of gravity acting on the weapon clearance appliance. Therefore, the weapon clearance appliance has neutral buoyancy, as a result of which, after the weapon clearance appliance has been released from the underwater vehicle, there is no need to retrim the underwater vehicle. Therefore, there is no need for trimming devices on the underwater vehicle.
