    In this thesis are analyzed different and innovative techniques for Human Robot Interaction. The focus of this thesis is on the interaction with flying robots. The first part is a preliminary description of the state of the art interactions techniques. Then the first project is Fly4SmartCity, where it is analyzed the interaction between humans (the citizen and the operator) and drones mediated by a cloud robotics platform. Then there is an application of the sliding autonomy paradigm and the analysis of different degrees of autonomy supported by a cloud robotics platform. The last part is dedicated to the most innovative technique for human-drone interaction in the User’s Flying Organizer project (UFO project). This project wants to develop a flying robot able to project information into the environment exploiting concepts of Spatial Augmented Realit

    Airspace – Zones of Fidelity and Failure

    Given our increasing reliance on air travel to function in all aspects of society, it seems imperative to expand our knowledge of airspace and the social relations that air travel enhances and makes possible. My thesis offers a critical analysis of the technical safety systems that support air travel. It finds fissures in the rationality that underlines our belief in the safety and sustainability of air travel and leaves open the question of whether our confidence in this system can be sustained only by the claim that it is inherently rational. According to anthropologists Geoffrey Bowker and Susan Leigh Star, one of the defining characteristics of technological systems that achieve the cultural status of ‘infrastructure’, is that they ‘become visible upon breakdown’. (Bowker and Star 2000, 335) Two real world events - a commercial airliner’s (Air New Zealand 901) collision with an Antarctic volcano, killing 257 people in 1979 and the closure of European airspace due to the presence of volcanic ash (eruption of Eyjafjallajökull, Iceland in 2010) expose the fragility of the infrastructural systems supporting air travel. As conditions of exceptionality, these events pose a challenge to aspects of our spatial imaginary, allowing us to understand the contradictory interdependence of trust and risk. Working across media, using video, sound, object making and print, my practice is concerned with the ‘breaking down’ of space. My work reflects my increasing interest in the precariousness of empirically grounded monolithic systems that aspire towards comprehensive totality and stability through their own set of formal logics and structural parameters

    The future of Earth observation in hydrology

    Get PDF
    In just the past 5 years, the field of Earth observation has progressed beyond the offerings of conventional space-agency-based platforms to include a plethora of sensing opportunities afforded by CubeSats, unmanned aerial vehicles (UAVs), and smartphone technologies that are being embraced by both for-profit companies and individual researchers. Over the previous decades, space agency efforts have brought forth well-known and immensely useful satellites such as the Landsat series and the Gravity Research and Climate Experiment (GRACE) system, with costs typically of the order of 1 billion dollars per satellite and with concept-to-launch timelines of the order of 2 decades (for new missions). More recently, the proliferation of smart-phones has helped to miniaturize sensors and energy requirements, facilitating advances in the use of CubeSats that can be launched by the dozens, while providing ultra-high (3-5 m) resolution sensing of the Earth on a daily basis. Start-up companies that did not exist a decade ago now operate more satellites in orbit than any space agency, and at costs that are a mere fraction of traditional satellite missions. With these advances come new space-borne measurements, such as real-time high-definition video for tracking air pollution, storm-cell development, flood propagation, precipitation monitoring, or even for constructing digital surfaces using structure-from-motion techniques. Closer to the surface, measurements from small unmanned drones and tethered balloons have mapped snow depths, floods, and estimated evaporation at sub-metre resolutions, pushing back on spatio-temporal constraints and delivering new process insights. At ground level, precipitation has been measured using signal attenuation between antennae mounted on cell phone towers, while the proliferation of mobile devices has enabled citizen scientists to catalogue photos of environmental conditions, estimate daily average temperatures from battery state, and sense other hydrologically important variables such as channel depths using commercially available wireless devices. Global internet access is being pursued via high-altitude balloons, solar planes, and hundreds of planned satellite launches, providing a means to exploit the "internet of things" as an entirely new measurement domain. Such global access will enable real-time collection of data from billions of smartphones or from remote research platforms. This future will produce petabytes of data that can only be accessed via cloud storage and will require new analytical approaches to interpret. The extent to which today's hydrologic models can usefully ingest such massive data volumes is unclear. Nor is it clear whether this deluge of data will be usefully exploited, either because the measurements are superfluous, inconsistent, not accurate enough, or simply because we lack the capacity to process and analyse them. What is apparent is that the tools and techniques afforded by this array of novel and game-changing sensing platforms present our community with a unique opportunity to develop new insights that advance fundamental aspects of the hydrological sciences. To accomplish this will require more than just an application of the technology: in some cases, it will demand a radical rethink on how we utilize and exploit these new observing systems

    Air space: towards a social and cultural geography of global air travel

    Get PDF
    Geographic research into commercial aviation has traditionally been undertaken within the field of transport geography. While such studies have shed light on the increasingly complex morphology of global air routes, this paper argues such approaches often downplay crucial questions concerning the social production and consumption of different spaces of air travel. Drawing on ideas from the newlyemergent ‘mobilities' paradigm, this paper identifies some alternative geographies of air travel, arguing that socially- and culturally-inflected perspectives may help reveal the iniquitous imprints of global air travel at a variety of spatial scales. We suggest that there is much to be gained by adopting such perspectives, and argue that work on the social dimensions of air travel is vital in a discipline where air transport is routinely described as an enabler of globalisation, yet is often treated as an abstract, and oddly disembodied, space of flows

    Producing airspace : the contested geographies of Nottingham East Midlands Airport

    Get PDF
    During the last 100 years, commercial aviation has developed into an established mode of transportation serving millions of passengers every year, but while researchers from other disciplines - most notably sociology, cultui-al history, and anthropology - have begun to appreciate the multiple dimensions of flight, geographers have written surprisingly little on the subject beyond quantitative analyses of airline networks. While perhaps understandable given the present geopolitical climate of passenger (in)security and commercial confidentiality, this nevertheless means many of the industry's significant facets have yet to be adequately charted. Considering geography's rich heritage of examining space, place, and spatial phenomena at a variety of scales, this thesis provides a distinctive contribution to theoretical and empirical knowledge by addressing the multiple geographies of airspace. Set in the context of the ongoing controversy surrounding the reorganisation offlightpaths at Nottingham East Midlands Airport (NEMA) in the United Kingdom, it considers the inherently geographical and often contested nature of airspace production. By detailing the complex interplay between how airspace is produced 'on the ground' by those who oppose its use, and 'in the air' by Air Traffic Controllers and airline pilots, it offers a new perspective for studies of geography and air transport in an age of mass aeromobility.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

    The Air Transportation Management (ATM) Workshop was held 31 Jan. - 1 Feb. 1995 at NASA Ames Research Center. The purpose of the workshop was to develop an initial understanding of user concerns and requirements for future ATM capabilities and to initiate discussions of alternative means and technologies for achieving more effective ATM capabilities. The topics for the sessions were as follows: viewpoints of future ATM capabilities, user requirements, lessons learned, and technologies for ATM. In addition, two panel sessions discussed priorities for ATM, and potential contributions of NASA to ATM. The proceedings contain transcriptions of all sessions
