    We can no longer interpret the contemporary metropolis as we did in the last century. The thought of civil economy regarding the contemporary Metropolis conflicts more or less radically with the merely acquisitive dimension of the behaviour of its citizens. What is needed is therefore a new capacity for imagining the economic-productive future of the city: hybrid social enterprises, economically sustainable, structured and capable of using technologies, could be a solution for producing value and distributing it fairly and inclusively. Metropolitan Urbanity is another issue to establish. Metropolis needs new spaces where inclusion can occur, and where a repository of the imagery can be recreated. What is the ontology behind the technique of metropolitan planning and management, its vision and its symbols? Competitiveness, speed, and meritocracy are political words, not technical ones. Metropolitan Urbanity is the characteristic of a polis that expresses itself in its public places. Today, however, public places are private ones that are destined for public use. The Common Good has always had a space of representation in the city, which was the public space. Today, the Green-Grey Infrastructure is the metropolitan city's monument that communicates a value for future generations and must therefore be recognised and imagined; it is the production of the metropolitan symbolic imagery, the new magic of the city

    This thesis describes the development of the Sample Fetch Rover (SFR), studied for Mars Sample Return (MSR), an international campaign carried out in cooperation between the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). The focus of this document is the design of the electro-mechanical systems of the rover. After placing this work into the general context of robotic planetary exploration and summarising the state of the art for what concerns Mars rovers, the architecture of the Mars Sample Return Campaign is presented. A complete overview of the current SFR architecture is provided, touching upon all the main subsystems of the spacecraft. For each area, it is discussed what are the design drivers, the chosen solutions and whether they use heritage technology (in particular from the ExoMars Rover) or new developments. This research focuses on two topics of particular interest, due to their relevance for the mission and the novelty of their design: locomotion and sample acquisition, which are discussed in depth. The early SFR locomotion concepts are summarised, covering the initial trade-offs and discarded designs for higher traverse performance. Once a consolidated architecture was reached, the locomotion subsystem was developed further, defining the details of the suspension, actuators, deployment mechanisms and wheels. This technology is presented here in detail, including some key analysis and test results that support the design and demonstrate how it responds to the mission requirements. Another major electro-mechanical system developed as part of this work is the one dedicated to sample tube acquisition. The concept of operations of this machinery was defined to be robust against the unknown conditions that characterise the mission. The design process led to a highly automated robotic system which is described here in its main components: vision system, robotic arm and tube storage

    The Cultural Politics of Anti-Elitism

    Full text link
    This book examines the highly ambivalent implications and effects of anti-elitism. It draws on this theme as a cross-cutting entry point to provide transdisciplinary analysis of current conjunctures and their contradictions, drawing on examples from popular culture and media, politics, fashion, labour and spatial arrangements. Using the toolboxes of media and discourse analysis, hegemony theory, ethnography, critical social psychology and cultural studies more broadly, the book surveys and theorizes the forms, the implications and the ambiguities and limits of anti-elitist formations in different parts of the world. Anti-elitist sentiments colour the contemporary political conjuncture as much as they shape pop cultural and media trends. Populists, right-wing authoritarian ones and others, direct their anger at cultural, political and, sometimes, economic elites while supporting other elites and creating new ones. At the same time, "elitist" knowledge and expertise, decision-making power and taste regimes are being questioned in societal transformations that are discussed much more positively under headlines such as participation or democratization. The book brings together a group of international, interdisciplinary case studies in order to better understand the ways in which the battle cry "against the elites" shapes current conjunctures and possible future politics, focusing on themes such as nationalist political discourse in India, Austria, the UK and Hungary, labour struggles and anti-oligarchy rhetoric in Russia, tax-avoiding elites and fiscal imaginaries, working-class agency, Melania Trump as a celebrity narrative in Slovenia, aesthetic codes of the Alt-Right, football hooliganism in Germany, "hipster hate" in German political discourse or the politics of expertise and anti-elite iconography in high fashion internationally. The book is intended for undergraduates, postgraduates and postdoctoral researchers

    Welfare technologies in Finland: An ethico-politics of hype, hope and experimentation

    Get PDF
    In the past decade, the Finnish government has been eager to enable and support the development, implementation and growing business of automation, robotics and artificial intelligence—that is, welfare technologies in elderly care services. In these visions, technologies offer an intervention to increase health and wellbeing while also being an economic commodity to generate profit. Therefore, expectations towards welfare technologies show politics with high optimism, in which simultaneous expectations of good health, smooth services, a growing economy and a thriving welfare state are fostered. This dissertation delves into a problem in which care politics raise high expectations of technology while catering to the needs of the ageing population. My main research question is as follows: How are the high expectations related to the technology realised in care practices, and what are the ethico-political implications? This dissertation consists of four articles that exemplify the different dimensions of realising these expectations. The dissertation is theoretically based on multiple perspectives from science and technology studies. My theoretical framework enables a focus on ethico-political practices and expectations, offers a symmetrical approach to care and technology and provides a critical viewpoint to the technological promises laid in contemporary care politics. I use multi-sited ethnography as a methodology. The research materials consist of documents, observations and interviews. The focus of the empirical materials is on social robots and telecare technology—that is, robots designed to provide companionship and assistance and surveillance technologies for secure care. I read the different research materials through the sociology of translations, which emphasises that the manner in which expectations are fulfilled concerns the adaptation and transformation of different actors and their aspirations. This dissertation advances the theoretical and empirical understanding of the welfare technology phenomenon. My main argument is that expectations related to welfare technologies in Finland are realised in actual care practices through negotiations between the regimes of hype and hope. The regime of hype captures the health and social policy side of the welfare technology phenomenon, while the regime of hope mainly concerns institutional care. Hype creates, collects and circulates optimistic expectations, while hope enables living with the uncertainty that comes with technology’s material agency. With technology comes the possibility of disruption, which intervenes with care relations and, paradoxically, enables them by offering possibilities for creativity. Experimentation is central to both regimes. While experimentation in the regime of hype aims at fulfilling optimistic expectations, experimentation in the regime of hope is obligatory to secure care. Experimentation in practice makes the wellbeing of individuals and the state commensurate, transforming disappointments into achievements and technological possibilities into necessities. Both regimes value ambivalence and uncertainty due to their shared focus on experimentation.----- Tarkastelen sosiologian alaan kuuluvassa väitöskirjassa iäkkäiden hoivatyöhön suunnattuihin hyvinvointiteknologioihin liittyviä odotuksia sekä niiden eettis-poliittisia vaikutuksia. Väitöskirja koostuu neljästä vertaisarvioidusta tutkimusartikkelista ja yhteenvetoluvusta. Kaksi artikkeleista on julkaistu kansainvälisissä ja kaksi kotimaisissa lehdissä. Tutkimus paikantuu suomalaisen hyvinvointivaltion ja sen hoivapalvelujen murroskohtaan, jossa riittämättömiin hoivaresursseihin haetaan poliittista ratkaisua automaatiosta, tekoälystä ja robotiikasta. Hyvinvointiteknologian käsite viittaa pohjoismaisten hyvinvointivaltioiden pyrkimyksiin vastata ikääntyvän väestön tuomiin haasteisiin teknologisilla innovaatioilla samalla uusia yritysmahdollisuuksia kehittäen ja julkista taloutta eheyttäen. Päätutkimuskysymykseni on: Miten hyvinvointiteknologioihin liittyvät odotukset käytännössä toteutetaan ja millaisin eetis-poliittisin seurauksin? Teoreettisesti tutkimus paikantuu tieteen- ja teknologiantutkimuksen monitieteiseen kenttään. Osallistun erityisesti tutkimusalan keskusteluihin, jotka lähestyvät hoivaa, ikääntymistä ja teknologiaa sekä näihin liittyvää etiikkaa ja politiikkaa käytäntöjen kautta, eivät tee lähtökohtaista erottelua hoivaan liittyvien inhmillisten ja ei-inhimillisten toimijoiden välille sekä mahdollistavat kriittisen tulokulman hyvinvointiteknologiaan kohdistuviin lupauksiin. Metodologisesti tutkimus pohjautuu monipaikkaiseen etnografiaan. Keräämäni aineistot koostuvat dokumenteista, havainnointiaineistosta ja haastatteluista. Lähestyn hyvinvointiteknologian ilmiötä etenkin sosiaalisen robotiikan ja etähoivateknologian kautta. Analysoin aineistoja käännösten sosiologian avulla eli paneutumalla siihen, miten teknologioihin liittyvien lupausten toteutuminen on riippuvaista käännösprosesseista, joissa erilaiset toimijat ja niiden tavoitteet määrittyvät uusiksi. Tutkimus kontribuoi yhteiskuntatieteelliseen hyvinvointiteknologioiden ja iäkkäiden hoivan tutkimukseen tarkastelemalla monipaikkaisesti, miten uusiin teknologioihin liittyvät, eettis-poliittisesti latautuneet ja tulevaisuuteen kohdistuvat, odotukset taipuvat osaksi hoivatyön arkea sitä samalla muuttaen. Tutkimuksessa näytän, miten hyvinvointiteknologiaan liittyvät odotukset toteutuvat käytännössä jännitteisten neuvotteluiden kautta. Väitän, että hyvinvointiteknologiaan liittyvien odotusten toteuttaminen liittyy Suomessa kahteen erilaiseen, hypen ja toivon, regiimiin. Siinä missä hypen regiimi kuvaa hyvinvointiteknologioihin liittyvien suurten odotusten politiikkaa, toivon regiimi havainnollistaa uusien teknologioiden kanssa elettyä hoivan arkea. Molemmat regiimit painottavat kokeellisuutta. Siinä missä hypen regiimissä kokeellisuuden avulla toteutetaan teknologiaan liittyviä lupauksia, toivon regiimissä kokeellisuus on välttämätöntä hyvän hoivan turvaamiseksi. Käytännössä kokeellisuus on keino yhteismitallistaa yksilön ja valtion hyvinvointi, muuttaa pettymykset saavutuksiksi ja teknologiset mahdollisuudet välttämättömyyksiksi. Kokeellisuudesta seuraa, että molemmissa regiimeissä hyödynnetään epävarmuutta resurssina

    Snake and Snake Robot Locomotion in Complex, 3-D Terrain

    Get PDF
    Snakes are able to traverse almost all types of environments by bending their elongate bodies in three dimensions to interact with the terrain. Similarly, a snake robot is a promising platform to perform critical tasks in various environments. Understanding how 3-D body bending effectively interacts with the terrain for propulsion and stability can not only inform how snakes move through natural environments, but also inspire snake robots to achieve similar performance to facilitate humans. How snakes and snake robots move on flat surfaces has been understood relatively well in previous studies. However, such ideal terrain is rare in natural environments and little was understood about how to generate propulsion and maintain stability when large height variations occur, except for some qualitative descriptions of arboreal snake locomotion and a few robots using geometric planning. To bridge this knowledge gap, in this dissertation research we integrated animal experiments and robotic studies in three representative environments: a large smooth step, an uneven arena of blocks of large height variation, and large bumps. We discovered that vertical body bending induces stability challenges but can generate large propulsion. When traversing a large smooth step, a snake robot is challenged by roll instability that increases with larger vertical body bending because of a higher center of mass. The instability can be reduced by body compliance that statistically increases surface contact. Despite the stability challenge, vertical body bending can potentially allow snakes to push against terrain for propulsion similar to lateral body bending, as demonstrated by corn snakes traversing an uneven arena. This ability to generate large propulsion was confirmed on a robot if body-terrain contact is well maintained. Contact feedback control can help the strategy accommodate perturbations such as novel terrain geometry or excessive external forces by helping the body regain lost contact. Our findings provide insights into how snakes and snake robots can use vertical body bending for efficient and versatile traversal of the three-dimensional world while maintaining stability

    Locomotion system for ground mobile robots in uneven and unstructured environments

    Get PDF
    One of the technology domains with the greatest growth rates nowadays is service robots. The extensive use of ground mobile robots in environments that are unstructured or structured for humans is a promising challenge for the coming years, even though Automated Guided Vehicles (AGV) moving on flat and compact grounds are already commercially available and widely utilized to move components and products inside indoor industrial buildings. Agriculture, planetary exploration, military operations, demining, intervention in case of terrorist attacks, surveillance, and reconnaissance in hazardous conditions are important application domains. Due to the fact that it integrates the disciplines of locomotion, vision, cognition, and navigation, the design of a ground mobile robot is extremely interdisciplinary. In terms of mechanics, ground mobile robots, with the exception of those designed for particular surroundings and surfaces (such as slithering or sticky robots), can move on wheels (W), legs (L), tracks (T), or hybrids of these concepts (LW, LT, WT, LWT). In terms of maximum speed, obstacle crossing ability, step/stair climbing ability, slope climbing ability, walking capability on soft terrain, walking capability on uneven terrain, energy efficiency, mechanical complexity, control complexity, and technology readiness, a systematic comparison of these locomotion systems is provided in [1]. Based on the above-mentioned classification, in this thesis, we first introduce a small-scale hybrid locomotion robot for surveillance and inspection, WheTLHLoc, with two tracks, two revolving legs, two active wheels, and two passive omni wheels. The robot can move in several different ways, including using wheels on the flat, compact ground,[1] tracks on soft, yielding terrain, and a combination of tracks, legs, and wheels to navigate obstacles. In particular, static stability and non-slipping characteristics are considered while analyzing the process of climbing steps and stairs. The experimental test on the first prototype has proven the planned climbing maneuver’s efficacy and the WheTLHLoc robot's operational flexibility. Later we present another development of WheTLHLoc and introduce WheTLHLoc 2.0 with newly designed legs, enabling the robot to deal with bigger obstacles. Subsequently, a single-track bio-inspired ground mobile robot's conceptual and embodiment designs are presented. This robot is called SnakeTrack. It is designed for surveillance and inspection activities in unstructured environments with constrained areas. The vertebral column has two end modules and a variable number of vertebrae linked by compliant joints, and the surrounding track is its essential component. Four motors drive the robot: two control the track motion and two regulate the lateral flexion of the vertebral column for steering. The compliant joints enable limited passive torsion and retroflection of the vertebral column, which the robot can use to adapt to uneven terrain and increase traction. Eventually, the new version of SnakeTrack, called 'Porcospino', is introduced with the aim of allowing the robot to move in a wider variety of terrains. The novelty of this thesis lies in the development and presentation of three novel designs of small-scale mobile robots for surveillance and inspection in unstructured environments, and they employ hybrid locomotion systems that allow them to traverse a variety of terrains, including soft, yielding terrain and high obstacles. This thesis contributes to the field of mobile robotics by introducing new design concepts for hybrid locomotion systems that enable robots to navigate challenging environments. The robots presented in this thesis employ modular designs that allow their lengths to be adapted to suit specific tasks, and they are capable of restoring their correct position after falling over, making them highly adaptable and versatile. Furthermore, this thesis presents a detailed analysis of the robots' capabilities, including their step-climbing and motion planning abilities. In this thesis we also discuss possible refinements for the robots' designs to improve their performance and reliability. Overall, this thesis's contributions lie in the design and development of innovative mobile robots that address the challenges of surveillance and inspection in unstructured environments, and the analysis and evaluation of these robots' capabilities. The research presented in this thesis provides a foundation for further work in this field, and it may be of interest to researchers and practitioners in the areas of robotics, automation, and inspection. As a general note, the first robot, WheTLHLoc, is a hybrid locomotion robot capable of combining tracked locomotion on soft terrains, wheeled locomotion on flat and compact grounds, and high obstacle crossing capability. The second robot, SnakeTrack, is a small-size mono-track robot with a modular structure composed of a vertebral column and a single peripherical track revolving around it. The third robot, Porcospino, is an evolution of SnakeTrack and includes flexible spines on the track modules for improved traction on uneven but firm terrains, and refinements of the shape of the track guidance system. This thesis provides detailed descriptions of the design and prototyping of these robots and presents analytical and experimental results to verify their capabilities
