Design of Interactive Service Robots applying methods of Systems Engineering and Decision Making

Interaktive Service Roboter werden heute bereits in einigen Anwendungsszenarien eingesetzt, in denen sie beispielsweise Menschen durch Gebäude geleiten oder bei häuslichen Aufgaben unterstützen. Dennoch gibt es bislang kein System, das den erwarteten Marktdurchbruch geschafft hat. Die hohe Komplexität solcher Systeme und vielfältige Anforderungen durch Benutzer und Betreiber erschweren die Entwicklung von erfolgreichen Service Robotern. In dieser Arbeit wurden zwei interaktive Service Roboter entwickelt, die das Potential haben, die beschriebenen Hinderungsgründe für einen breiten Einsatz zu überwinden. Das erste Robotersystem wurde als Shopping Roboter für Baumärkte entwickelt, in denen es Kunden zu gesuchten Produkten führt. Das zweite System dient als interaktiver Pflegeroboter älteren Menschen in häuslicher Umgebung bei der Bewältigung täglicher Aufgaben. Diese Arbeit beschreibt die Realisierung der Embedded Systems beider Robotersysteme und umfasst insbesondere die Entwicklung der Low-Level System Architekturen, Energie Management Systeme, Kommunikationssysteme, Sensorsysteme, sowie ausgewählte Aspekte der mechanischen Umsetzung. Die Entwicklung einer Vielzahl von Steuerungsmodulen, notwendig für die Realisierung interaktiver Service Roboter, wird beschrieben. Die vorliegende Arbeit verwendet und erweitert Methoden des Systems Engineerings, um die hohe Systemkomplexität von interaktiven Service Robotern sowie die vielfältigen Anforderungen an deren späteren Einsatz beherrschen zu können. Der Entwicklungsprozess der beiden Roboter basiert auf dem V-Model, welches einen strukturierten Entwurfsablauf unter Berücksichtigung aller Systemanforderungen erlaubt. Es zwingt ferner zur frühzeitigen Spezifikation von Prüfabläufen, was die Qualität und Zuverlässigkeit der Entwicklungsergebnisse verbessert. Für die Unterstützung von Entscheidungen im Entwicklungsprozess schlägt diese Arbeit eine Kombination aus dem V-Model und dem Analytic Hierarchy Process (AHP) vor. Der AHP hilft bei der Auswahl verfügbarer technischer Alternativen unter Berücksichtigung von Prioritäten im Entwicklungsprozess. Diese Arbeit spezifiziert sieben Kriterien, die Service Roboter charakterisieren: Anpassbarkeit, Laufzeit, Benutzbarkeit, Robustheit, Sicherheit, Features und Kosten. Die Prioritäten dieser Kriterien im Entwicklungsprozess werden für jeden Roboter individuell bestimmt. Der AHP ermittelt die beste Lösung basierend auf diesen gewichteten Kriterien und den bewerteten technischen Alternativen. Die Einbindung des AHP in den V-Model Prozess wurde am Entwurf des Shopping Roboter entwickelt und geprüft. Die Allgemeingültigkeit dieser Methode wurde während der Entwicklung des Pflegeroboters verifiziert.Interactive service robots have already been developed and operate as example installations taking over guidance tasks or serving as home assistants. However, none of these systems have become an off-the-shelf product or have achieved the predicted breakthrough so far. The challenges of the design of such systems are, on the one hand, the combination of cutting edge technologies to a complex product; on the other hand, the consideration of requirements important for the later marketing during the design process. In the framework of this dissertation, two interactive service robot systems are developed that have the potential to overcome current market entry barriers. These robots are designed to operate in two different environments: one robot guides walked-in users in large home improvement stores to requested product locations and interacts with the customer to provide product information; the other robot assists elderly people to stay longer in their homes and takes over home-care tasks. This work describes the realization of the embedded systems of both robots. In particular, the design of low-level system architectures, energy management systems, communication systems, sensor systems, and selected aspects of mechanical implementations are carried out in this work. Multiple embedded system modules are developed for the control of the robots' functionalities; the development processes as well as the composition and evaluation of these modules are presented in this work. To cope with the complexity and the various factors that are important for the design of the robots, this thesis applies and further develops system engineering methods. The development process is based on the V-Model system design method. The V-Model helps to structure the design process under consideration of all system requirements. It involves evaluation procedures at all design levels, and thus increases the quality and reliability of the development outputs. To support design decisions, this thesis proposes to combine the V-Model with the Analytic Hierarchy Process (AHP) method. The AHP helps to evaluate technical alternatives for design decisions according to overall criteria, a system has to fulfill. This thesis defines seven criteria that characterize a service robot: Adaptability, Operation Time, Usability, Robustness, Safeness, Features, and Costs. These criteria are weighted for each individual robot application. The AHP evaluates technical design alternatives based on the weighted criteria to reveal the best technical solution. The integration of the AHP into the V-Model development is tested and improved during the design process of the shopping robot system. The generality of this combined systematic design approach is validated during the design of the home-care robot system

Production Engineering and Management

The annual International Conference on Production Engineering and Management takes place for the sixth time his year, and can therefore be considered a well - established event that is the result of the joint effort of the OWL University of Applied Sciences and the University of Trieste. The conference has been established as an annual meeting under the Double Degree Master Program ‘Production Engineering and Management’ by the two partner universities. The main goal of the conference is to provide an opportunity for students, researchers and professionals from Germany, Italy and abroad, to meet and exchange information, discuss experiences, specific practices and technical solutions used in planning, design and management of production and service systems. In addition, the conference is a platform aimed at presenting research projects, introducing young academics to the tradition of Symposiums and promoting the exchange of ideas between the industry and the academy. Especially the contributions of successful graduates of the Double Degree Master Program ‘Production Engineering and Management’ and those of other postgraduate researchers from several European countries have been enforced. This year’s special focus is on Direct Digital Manufacturing in the context of Industry 4.0, a topic of great interest for the global industry. The concept is spreading, but the actual solutions must be presented in order to highlight the practical benefits to industry and customers. Indeed, as Henning Banthien, Secretary General of the German ‘Plattform Industrie 4.0’ project office, has recently remarked, “Industry 4.0 requires a close alliance amongst the private sector, academia, politics and trade unions” in order to be “translated into practice and be implemented now”. PEM 2016 takes place between September 29 and 30, 2016 at the OWL University of Applied Sciences in Lemgo. The program is defined by the Organizing and Scientific Committees and clustered into scientific sessions covering topics of main interest and importance to the participants of the conference. The scientific sessions deal with technical and engineering issues, as well as management topics, and include contributions by researchers from academia and industry. The extended abstracts and full papers of the contributions underwent a double - blind review process. The 24 accepted presentations are assigned, according to their subject, to one of the following sessions: ‘Direct Digital Manufacturing in the Context of Industry 4.0’, ‘Industrial Engineering and Lean Management’, ‘Management Techniques and Methodologies’, ‘Wood Processing Technologies and Furniture Production’ and ‘Innovation Techniques and Methodologies

Tangible user interfaces : past, present and future directions

In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users' knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive research is required in or- der to fully understand the implications of tangible user interfaces, to develop technologies that further bridge the digital and the physical, and to guide TUI design with empirical knowledge. This paper examines the existing body of work on Tangible User In- terfaces. We start by sketching the history of tangible user interfaces, examining the intellectual origins of this field. We then present TUIs in a broader context, survey application domains, and review frame- works and taxonomies. We also discuss conceptual foundations of TUIs including perspectives from cognitive sciences, phycology, and philoso- phy. Methods and technologies for designing, building, and evaluating TUIs are also addressed. Finally, we discuss the strengths and limita- tions of TUIs and chart directions for future research

Developing a person guidance module for hospital robots

This dissertation describes the design and implementation of the Person Guidance Module (PGM) that enables the IWARD (Intelligent Robot Swarm for attendance, Recognition, Cleaning and delivery) base robot to offer route guidance service to the patients or visitors inside the hospital arena. One of the common problems encountered in huge hospital buildings today is foreigners not being able to find their way around in the hospital. Although there are a variety of guide robots currently existing on the market and offering a wide range of guidance and related activities, they do not fit into the modular concept of the IWARD project. The PGM features a robust and foolproof non-hierarchical sensor fusion approach of an active RFID, stereovision and cricket mote sensor for guiding a patient to the X-ray room, or a visitor to a patient’s ward in every possible scenario in a complex, dynamic and crowded hospital environment. Moreover, the speed of the robot can be adjusted automatically according to the pace of the follower for physical comfort using this system. Furthermore, the module performs these tasks in any unconstructed environment solely from a robot’s onboard perceptual resources in order to limit the hardware installation costs and therefore the indoor setting support. Similar comprehensive solution in one single platform has remained elusive in existing literature. The finished module can be connected to any IWARD base robot using quick-change mechanical connections and standard electrical connections. The PGM module box is equipped with a Gumstix embedded computer for all module computing which is powered up automatically once the module box is inserted into the robot. In line with the general software architecture of the IWARD project, all software modules are developed as Orca2 components and cross-complied for Gumstix’s XScale processor. To support standardized communication between different software components, Internet Communications Engine (Ice) has been used as middleware. Additionally, plug-and-play capabilities have been developed and incorporated so that swarm system is aware at all times of which robot is equipped with PGM. Finally, in several field trials in hospital environments, the person guidance module has shown its suitability for a challenging real-world application as well as the necessary user acceptance

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

A design space for social object labels in museums

Taking a problematic user experience with ubiquitous annotation as its point of departure, this thesis defines and explores the design space for Social Object Labels (SOLs), small interactive displays aiming to support users' in-situ engagement with digital annotations of physical objects and places by providing up-to-date information before, during and after interaction. While the concept of ubiquitous annotation has potential applications in a wide range of domains, the research focuses in particular on SOLs in a museum context, where they can support the institution's educational goals by engaging visitors in the interpretation of exhibits and providing a platform for public discourse to complement official interpretations provided on traditional object labels. The thesis defines and structures the design space for SOLs, investigates how they can support social interpretation in museums and develops empirically validated design recommendations. Reflecting the developmental character of the research, it employs Design Research as a methodological framework, which involves the iterative development and evaluation of design artefacts together with users and other stakeholders. The research identifies the particular characteristics of SOLs and structures their design space into ten high-level aspects, synthesised from taxonomies and heuristics for similar display concepts and complemented with aspects emerging from the iterative design and evaluation of prototypes. It presents findings from a survey exploring visitors' mental models, preferences and expectations of commenting in museums and translates them into requirements for SOLs. It reports on scenario-based design activities, expert interviews with museum professionals, formative user studies and co-design sessions, and two empirical evaluations of SOL prototypes in a gallery environment. Pulling together findings from these research activities it then formulates design recommendations for SOLs and supports them with related evidence and implementation examples. The main contributions are (i) to delineate and structure the design space for SOLs, which helps to ground SOLs in the literature and understand them as a distinct display concept with its own characteristics; (ii) to explore, for the first time, a visitor perspective on commenting in museums, which can inform research, development and policies on user-generated content in museums and the wider cultural heritage sector; (iii) to develop empirically validated design recommendations, which can inform future research and development into SOLs and related display concept. The thesis concludes by summarising findings in relation to its stated research questions, restating its contributions from ubiquitous computing, domain and methodology perspectives, and discussing open issues and future work

RFID Technology in Intelligent Tracking Systems in Construction Waste Logistics Using Optimisation Techniques

Construction waste disposal is an urgent issue for protecting our environment. This paper proposes a waste management system and illustrates the work process using plasterboard waste as an example, which creates a hazardous gas when land filled with household waste, and for which the recycling rate is less than 10% in the UK. The proposed system integrates RFID technology, Rule-Based Reasoning, Ant Colony optimization and knowledge technology for auditing and tracking plasterboard waste, guiding the operation staff, arranging vehicles, schedule planning, and also provides evidence to verify its disposal. It h relies on RFID equipment for collecting logistical data and uses digital imaging equipment to give further evidence; the reasoning core in the third layer is responsible for generating schedules and route plans and guidance, and the last layer delivers the result to inform users. The paper firstly introduces the current plasterboard disposal situation and addresses the logistical problem that is now the main barrier to a higher recycling rate, followed by discussion of the proposed system in terms of both system level structure and process structure. And finally, an example scenario will be given to illustrate the system’s utilization
