    In order to support the European Commission in the preparation of future initiatives fostering the sustainability of strategic supply chains, this study was commissioned to assess bottlenecks in the supply of materials needed for the development of technologies important to Europe's defence and civil industries. The study focuses on five dual-use technology areas, namely advanced batteries, fuel cells, robotics, unmanned vehicles and additive manufacturing (3D printing). The technologies are preselected on the basis of a previous study (EASME, 2017) that explored the dual-use potential of key enabling technologies in which Europe should strategically invest. In addition, this report examines how these technologies could address specific military needs and their differences in relation to civil needs and identified opportunities for future defence research areas that could potentially serve as a basis for the design of research initiatives to be funded under the future European Defence Fund. Moreover, potential opportunities for common policy actions are also identified, notably: to strengthen Europe's position in the selected technologies’ supply chains; to facilitate collaboration between stakeholders; to increase industry involvement with special emphasis on small and medium-sized enterprises; to improve existent legislation; and increase synergies between civil and defence sectors in order to speed up progress in promising research areas.JRC.C.7-Knowledge for the Energy Unio

    ATTITUDE AWARE SMARTPHONES FOR TELE-OPERATED ROBOT CONTROL

    The U.S. military has increasingly turned to unmanned ground vehicles (UGVs) to assist in the most dull, dirty, and dangerous missions. Their presence on the battlefield is redefining how war is waged, expanding opportunities for reconnaissance and surveillance while minimizing soldier mortality. Robotic systems have gotten ever smaller, many now being man-packable. Soldiers may now carry, deploy, and control their own robotic assistant, many with limited formal training. Unfortunately, UGVs add significantly to a soldier's standard load of water, ammunition, armor, and supplies, making weight and portability top concerns. One way to ease the soldier burden is to adopt smartphones for use as robot operator control units (OCUs). Their small, lightweight frame combined with processing power and adaptable software backbone may enable intuitive controls on a device well-suited for other military missions.Field operations are often conducted when users are gloved and/or dirty, making common smartphone touch interfaces problematic. By using proprioceptive device inputs related to attitude, smartphones can be used for control in ways that minimize that touch interface. To test this, an attitude aware smartphone controller (using the device's accelerometers and gyroscope) for a small, tele-operated, ground robot was developed and assessed via a multi-phase usability experiment. The controller's motion algorithm made use of quaternion mathematics to simplify motion handling and the user interface.Twenty-five users were recruited to assess usability of attitude aware controls, testing their suitability for driving and camera manipulation tasks. Participants operated a small tracked robot on an indoor course with controllers using either virtual joystick or tilt-based controls while metrics regarding performance, mental workload, and user satisfaction were collected. They were also exposed to customizable controls, identifying modes and settings which contributed most heavily to the controller's usability. Results indicate that attitude-based controls are suitable for tele-operated reconnaissance and surveillance, as 64% of users preferred tilt-based driving controls while performing equally as well as the alternative. Customized configurations showed 60% of users preferred tilt for driving tasks when throttle sensitivity and controller responsiveness could be manipulated. The inherent usability of attitude aware controls optimistically exhibit how smartphones can be leveraged for robotic control, even in harsh environments by gloved users

    This thesis proposes a new virtual simulation environment designed as element of an interoperable federation of simulator to support the investigation of complex scenarios over the Extended Maritime Framework (EMF). Extended Maritime Framework is six spaces environment (Underwater, Water surface, Ground, Air, Space, and Cyberspace) where parties involved in Joint Naval Operations act. The amount of unmanned vehicles involved in the simulation arise the importance of the Communication modelling, thus the relevance of Cyberspace. The research is applied to complex cases (one applied to deep waters and one to coast and littoral protection) as examples to validate this approach; these cases involve different kind of traditional assets (e.g. satellites, helicopters, ships, submarines, underwater sensor infrastructure, etc.) interact dynamically and collaborate with new autonomous systems (i.e. AUV, Gliders, USV and UAV). The use of virtual simulation is devoted to support validation of new concepts and investigation of collaborative engineering solutions by providing a virtual representation of the current situation; this approach support the creation of dynamic interoperable immersive framework that could support training for Man in the Loop, education and tactical decision introducing the Man on the Loop concepts. The research and development of the Autonomous Underwater Vehicles requires continuous testing so a time effective approach can result a very useful tool. In this context the simulation can be useful to better understand the behaviour of Unmanned Vehicles and to avoid useless experimentations and their costs finding problems before doing them. This research project proposes the creation of a virtual environment with the aim to see and understand a Joint Naval Scenario. The study will be focusing especially on the integration of Autonomous Systems with traditional assets; the proposed simulation deals especially with collaborative operation involving different types of Autonomous Underwater Vehicles (AUV), Unmanned Surface Vehicles (USV) and UAV (Unmanned Aerial Vehicle). The author develops an interoperable virtual simulation devoted to present the overall situation for supervision considering also the sensor capabilities, communications and mission effectiveness that results dependent of the different asset interaction over a complex heterogeneous network. The aim of this research is to develop a flexible virtual simulation solution as crucial element of an HLA federation able to address the complexity of Extended Maritime Framework (EMF). Indeed this new generation of marine interoperable simulation is a strategic advantage for investigating the problems related to the operational use of autonomous systems and to finding new ways to use them respect to different scenarios. The research deal with the creation of two scenarios, one related to military operations and another one on coastal and littoral protection where the virtual simulation propose the overall situation and allows to navigate into the virtual world considering the complex physics affecting movement, perception, interaction and communication. By this approach, it becomes evident the capability to identify, by experimental analysis within the virtual world, the new solutions in terms of engineering and technological configuration of the different systems and vehicles as well as new operational models and tactics to address the specific mission environment. The case of study is a maritime scenario with a representation of heterogeneous network frameworks that involves multiple vehicles both naval and aerial including AUVs, USVs, gliders, helicopter, ships, submarines, satellite, buoys and sensors. For the sake of clarity aerial communications will be represented divided from underwater ones. A connection point for the latter will be set on the keel line of surface vessels representing communication happening via acoustic modem. To represent limits in underwater communications, underwater signals have been considerably slowed down in order to have a more realistic comparison with aerial ones. A maximum communication distance is set, beyond which no communication can take place. To ensure interoperability the HLA Standard (IEEE 1516 evolved) is adopted to federate other simulators so to allow its extensibility for other case studies. Two different scenarios are modelled in 3D visualization: Open Water and Port Protection. The first one aims to simulate interactions between traditional assets in Extended Maritime Framework (EMF) such as satellite, navy ships, submarines, NATO Research Vessels (NRVs), helicopters, with new generation unmanned assets as AUV, Gliders, UAV, USV and the mutual advantage the subjects involved in the scenario can have; in other word, the increase in persistence, interoperability and efficacy. The second scenario models the behaviour of unmanned assets, an AUV and an USV, patrolling a harbour to find possible threats. This aims to develop an algorithm to lead patrolling path toward an optimum, guaranteeing a high probability of success in the safest way reducing human involvement in the scenario. End users of the simulation face a graphical 3D representation of the scenario where assets would be represented. He can moves in the scenario through a Free Camera in Graphic User Interface (GUI) configured to entitle users to move around the scene and observe the 3D sea scenario. In this way, players are able to move freely in the synthetic environment in order to choose the best perspective of the scene. The work is intended to provide a valid tool to evaluate the defencelessness of on-shore and offshore critical infrastructures that could includes the use of new technologies to take care of security best and preserve themselves against disasters both on economical and environmental ones

    Search and rescue (SAR) operations can take significant advantage from supporting autonomous or teleoperated robots and multi-robot systems. These can aid in mapping and situational assessment, monitoring and surveillance, establishing communication networks, or searching for victims. This paper provides a review of multi-robot systems supporting SAR operations, with system-level considerations and focusing on the algorithmic perspectives for multi-robot coordination and perception. This is, to the best of our knowledge, the first survey paper to cover (i) heterogeneous SAR robots in different environments, (ii) active perception in multi-robot systems, while (iii) giving two complementary points of view from the multi-agent perception and control perspectives. We also discuss the most significant open research questions: shared autonomy, sim-to-real transferability of existing methods, awareness of victims' conditions, coordination and interoperability in heterogeneous multi-robot systems, and active perception. The different topics in the survey are put in the context of the different challenges and constraints that various types of robots (ground, aerial, surface, or underwater) encounter in different SAR environments (maritime, urban, wilderness, or other post-disaster scenarios). The objective of this survey is to serve as an entry point to the various aspects of multi-robot SAR systems to researchers in both the machine learning and control fields by giving a global overview of the main approaches being taken in the SAR robotics area
