Development, Control, and Empirical Evaluation of the Six-Legged Robot SpaceClimber Designed for Extraterrestrial Crater Exploration

In the recent past, mobile robots played an important role in the field of extraterrestrial surface exploration. Unfortunately, the currently available space exploration rovers do not provide the necessary mobility to reach scientifically interesting places in rough and steep terrain like boulder fields and craters. Multi-legged robots have proven to be a good solution to provide high mobility in unstructured environments. However, space missions place high demands on the system design, control, and performance which are hard to fulfill with such kinematically complex systems. This thesis focuses on the development, control, and evaluation of a six-legged robot for the purpose of lunar crater exploration considering the requirements arising from the envisaged mission scenario. The performance of the developed system is evaluated and optimized based on empirical data acquired in significant and reproducible experiments performed in a laboratory environment in order to show thecapability of the system to perform such a task and to provide a basis for the comparability with other mobile robotic solutions

Merging the Natural with the Artificial: The Nature of a Machine and the Collapse of Cybernetics

This thesis is concerned with the rise and fall of cybernetics, understood as an inquiry regarding the nature of a machine. The collapse of this scientific movement, usually explained by external factors such as lack of funding, will be addressed from a philosophical standpoint. Delving deeper into the theoretical core of cybernetics, one could find that the contributions of William Ross Ashby and John von Neumann shed light onto the particular ways in which cybernetics understood the nature and behavior of a machine. Ross Ashby offered an account of the nature of a machine and then extended the scope of “the mechanical”. This extension would encompass areas that will later be shown to be problematic for mechanization, such as learning and adaptation. The way in which a machine-ontology was applied would trigger effects seemingly contrary to cybernetics’ own distinctive features. Von Neumann, on the other hand, tinkered with a mechanical model of the brain, realizing grave limitations that prompted him to look for an alternative for cybernetics to work on. The proposal that came out of this resulted in a serious blow against the theoretical core of cybernetics. Why did cybernetics collapse? The contributions coming from both thinkers, in their own ways, spelled out the main tenets of the cybernetic proposal. But these very contributions led to cybernetics’ own demise. The whole story can be framed under the rubric of a serious inquiry into the metaphysical underpinnings of a machine. The rise and fall of cybernetics could thus help us better understand what a machine is from a philosophical standpoint. Although a historical component is present, my emphasis relies on a philosophical consideration of the cybernetic phenomenon. This metaphysical dissection will attempt to clarify how a machine-based ontology remained at the core of cybernetics. An emerging link will hopefully lead towards establishing a tri-partite correlation between cybernetics’ own evolution, its theoretical core, and its collapse. It will hopefully show how cybernetic inquiries into the nature of a machine might have proved fatal to the very enterprise at large, due to unsolvable theoretical tensions

Towards Our Common Digital Future. Flagship Report.

In the report “Towards Our Common Digital Future”, the WBGU makes it clear that sustainability strategies and concepts need to be fundamentally further developed in the age of digitalization. Only if digital change and the Transformation towards Sustainability are synchronized can we succeed in advancing climate and Earth-system protection and in making social progress in human development. Without formative political action, digital change will further accelerate resource and energy consumption, and exacerbate damage to the environment and the climate. It is therefore an urgent political task to create the conditions needed to place digitalization at the service of sustainable development

Capitalism in the Platform Age. Emerging Assemblages of Labor and Welfare in Urban Spaces,

This two-part work brings together the outcomes of the Horizon 2020 Project PLUS, “Platform Labor in Urban Spaces”. Running from December 2018 to March 2022, which included an extension from December 2021 due to the COVID-19 pandemic, this research project investigated the main features and dimensions of the impact of digital platforms on the economy and society, with a specific focus on labour, urban transformations, and welfare. Sixteen partners, including universities, research centres, and cooperatives, investigated the operations of four digital platforms (AirBnb, Deliveroo, Helpling, and Uber) in seven European cities (Barcelona, Berlin, Bologna, Lisbon, London, Paris, and Tallin). The research involved, in different ways, municipalities, independent researchers, platform managers, and established grassroot unions. The fact that the four abovementioned platforms operate in diverse fields—accommodation, food delivery, domestic labour, and transport—has allowed us to carry out a wide-ranging analysis of the rapid spread of digital platforms across the economy and society

Internet Marketing for Profit Organizations: A framework for the implementation of strategic internet marketing

Merged with duplicate record 10026.1/828 on 13.03.2017 by CS (TIS)The development of the Internet has significantly changed the face of established markets and operation approaches across a tremendous spectrum of different industries. Within the competitive environment of those industries, the opportunities and risks derived from the new platform are so ubiquitous that unused opportunities quickly translate into potential risks. Those opportunities and risks demand for a structured approach how to implement a sustainable Internet marketing strategy that targets clear business objectives. Marketing and strategic management theory describes very clear structural principles towards their operational implementation. Based on those principles an extensive literature review has been conducted which confirms the result from representative statistics that demonstrate the lack of a comprehensive framework for strategic Internet marketing. The distinct result of this research is such a comprehensive framework which has been directly derived from the illustrated principles of strategic management and Internet marketing. All major components of this generic framework are designed, evaluated in dedicated surveys and validated in extensive case studies. The main achievements of the research are: • A comprehensive review of the current state-of-the-art Internet marketing strategies • Conceptual specification of a strategic Internet marketing framework with generic applicability to profit organizations • Demonstration of the practical feasibility of the proposed framework at the implementation level (via several examples like the SIMTF and SIMPF) • Confirmation of the applicability of the framework based upon a survey of potential beneficiaries • Validation of the effectiveness of the approach via case study scenarios Changing the understanding of a former technical discipline, the thesis describes how Internet marketing becomes a precise strategic instrument for profit organizations. The new structured, complete and self-similar framework facilitates sales organizations to significantly increase the effectiveness and efficiency of their marketing operations. Furthermore, the framework ensures a high level of transparency about the impact and benefit of individual activities. The new model explicitly answers concerns and problems raised and documented in existing research and accommodate for the current limitations of strategic Internet marketing. The framework allows evaluating existing as well as future Internet marketing tactics and provides a reference model for all other definitions of objectives, KPI and work packages. Finally this thesis also matures the subject matter of Internet marketing as a discipline of independent scientific research providing an underlying structure for subsequent studies.Darmstadt Node of the CSCAN Network at University of Applied Sciences, Darmstad
