Specific machines furnish the contemporary socio-technical imaginary: ‘Robot companions’ that supposedly herald the age of robots, an age that is signified by the realization of robot technologies that are taking over labor from humans in every sphere of ‘everyday human lives’. How do we want these robot companions to work and look and how do we want to live with these machines?  This thesis explores the engineering of relating humans and machines in the specific context of contemporary robotics from a queer feminist technoscience perspective. The ways in which such engineering processes implement ‘human-likeness’ in realizing the figure of the robot companion are of special concern. At the heart of this study is one robot model: Armar, developed at the Institute for Anthropomatics and Robotics at the Karlsruhe Institute of Technology. Participating in the local everyday practices of establishing the efficient robot-human interface in the kitchen laboratory, this study investigates the ways in which Armar is made domestic as a prospective care service provider and companion in the kitchen. This study applies a posthumanist frame of research to investigate the practices of making anthropomatic kitchen robots. It employs an understanding of this making in terms of ‘performing the kitchen’. This further entails querying the ways in which norms of ‘humanness’ are translated into the human-like robot as well as the idea of pre-figured embodied entities with individual properties that meet in the laboratory. Thus, this thesis maps the labors and reciprocities of learning to see and experience this specific robot model as a future human-like companion for humans by analyzing the apparatuses of bodily co-production between human and machine that are at work in the kitchen laboratory. / Avhandlingen undersöker sociotekniska processer inom samtida robotik som både upprätthåller och skapar människa – maskin relationer ur ett feministiskt teknovetenskapligt perspektiv. Speciellt undersöks hur ingenjörer skapar robot-människa gränssnitt för hushållsrobotik och implementerar människolikhet i skapandet av framtidens robotsällskap. En specifik robotmodell, Armar, och dess utveckling följs vid Institutet för Antropomatik och Robotik, Tekniska Högskola i Karlsruhe i södra Tyskland. Armar ”bor” och verkar där i ett kökslaboratorium, en simulerad vardagsyta utvecklad för forskning och offentliga demonstrationer. Men hushållsrobotar har också en speciell plats i vår kulturella föreställningsvärld. I denna studie undersöks det sociotekniska och kulturella processen att domesticera robotar och ge dem status som prospektiva hjälpredor och sällskap i köket. Som en sådan kartläggning av ömsesidigt människa-maskin skapande teoretiserar studien den kroppsproducerande apparaten (Haraway 1991) som sätts i spel i detta kökslabb och i robot-människa gränssnittet. I studien utforskas ickemänsklig agens och posthumanistisk performativitet (Barad 2003) samt gränsdragningsarbetet mellan Jaget och Andra, människa och maskin, subject och objekt. Avhandlingen gör ett bidrag till förståelsen av kroppsliga normer och socio-materiella ömsesidigheter i skapandet av förmänskligat robotsällskap. / Ob in Medienberichten oder Kinofilmen – aktuell prägen Maschinen das sozio-technische Imaginäre, die nach menschlichem Vorbild entwickelt werden, um in das ‘alltäglich-menschliche’ Leben einzutreten und dieses nachhaltig zu verändern. In ihrer Allgegenwärtigkeit künden sie das Zeitalter der Roboter an, das verspricht, den Lebensstandard, den sich der globale Norden zuschreibt, zu verbessern. Im Fokus dieser Studie steht ein spezifisches Robotermodell, Armar, das am Institut für Anthropomatik und Robotik des Instituts für Technologie in Karlsruhe (Deutschland) entwickelt wird. In der Analyse von Interviews, teilnehmender Beobachtung sowie Fotomaterial untersucht diese Studie die alltäglichen Praktiken im Robotik-Küchenlabor, durch die Armar zur Begleiter_in und Care-Arbeiter_in in der Küche wird. Die posthumanistische, queer-feministische Rahmung der Analyse erlaubt es, die Herstellung des anthropomatischen Küchenroboters als ein Performing the Kitchen zu verstehen. Die Arbeit fokussiert damit auf die Bedingungen und die Akteur_innen – sowohl menschliche als auch nichtmenschliche – und fragt nach den Normen des Menschlichen, die bei dem Arbeiten an einer ,menschenähnlichen‘ Maschine produziert, aber auch verändert werden. Dabei zeichnet sie nach, dass Entitäten mit verkörperten Eigenschaften nicht präexistieren, sondern aus komplexen Mensch-Maschine-Verhältnissen der Ko-Produktion hervorgehen.

Objectives The primary objective of this study was to investigate the effect of the video-based smartphone app ‘VIDEA bewegt’ over eight programme weeks on physical activity in German adults. - Design The study used a single-arm observational design, assessing the app’s effectiveness under real-life conditions. Data were collected from July 2019 to July 2020. - Setting The app is enabling users to access video-based educational content via their smartphone. A clinical visit or in-person contact was not required. Participants All individuals registered in the freely available app were invited to take part in the study. - Interventions The app aims to increase physical activity in everyday life. It combines educative videos on lifestyle-related benefits and instructional videos of strength and endurance exercises to do at home with motivational components like goal setting, documentation of progress and personalised messages. - Primary and secondary outcome measures Primary outcomes were physical activity based one MET minutes per week (metabolic equivalent) and step numbers. Secondary outcomes included physical self-efficacy (motivational, maintenance, recovery self-efficacy), health-related quality of life: Mental Health Component Summary score and Physical Health Component Summary score. - Results Of 97 people included in the data analysis, 55 successfully completed the programme and all questionnaires. Significant increases over eight programme weeks (between T0 and T2) were observed in physical activity based on MET minutes per week, health-related quality of life, and recovery self-efficacy. Time spent sitting and body mass index significantly decreased for those completing the programme. Conclusions Although significant benefits of physical activity were observed following a complete-case analysis, results should be dealt with caution. Studies with a larger and less heterogeneous sample and robust study designs able to measure causal effects would be desirable. Trial registration number DRKS00017392.
