Test moment determination design in active robot learning

A thesis submitted to the University of Bedfordshire, in fulfilment of the requirements for the degree of Master of Science by researchIn recent years, service robots have been increasingly used in people's daily live. These robots are autonomous or semiautonomous and are able to cooperate with their human users. Active robot learning (ARL) is an approach to the development of beliefs for the robots on their users' intention and preference, which is needed by the robots to facilitate the seamless cooperation with humans. This approach allows a robot to perform tests on its users and to build up the high-order beliefs according to the users' responses. This study carried out primary research on designing the test moment determination component in ARL framework. The test moment determination component is used to decide right moment of taking a test action. In this study, an action plan theory was suggested to synthesis actions into a sequence, that is, an action plan, for a given task. All actions are defined in a special format of precondition, action, post-condition and testing time. Forward chaining reasoning was introduced to establish connection between the actions and to synthesis individual actions into an action plan, corresponding to the given task. A simulation environment was set up where a human user and a service robot were modelled using MATLAB. Fuzzy control was employed for controlling the robot to carry out the cooperative action. In order to examine the effect of test moment determination component, simulations were performed to execute a scenario where a robot passes on an object to a human user. The simulation results show that an action plan can be formed according to provided conditions and executed by simulated models properly. Test actions were taken at the moment determined by the test moment determination component to find the human user's intention

The development of test action bank for active robot learning

A thesis submitted to the University of Bedfordshire, in fulfilment of the requirements for the degree of Master of Science by researchIn the rapidly expanding service robotics research area, interactions between robots and humans become increasingly cornmon as more and more jobs will require cooperation between the robots and their human users. It is important to address cooperation between a robot and its user. ARL is a promising approach which facilitates a robot to develop high-order beliefs by actively performing test actions in order to obtain its user's intention from his responses to the actions. Test actions are crucial to ARL. This study carried out primary research on developing a Test Action Bank (TAB) to provide test actions for ARL. In this study, a verb-based task classifier was developed to extract tasks from user's commands. Taught tasks and their corresponding test actions were proposed and stored in database to establish the TAB. A backward test actions retrieval method was used to locate a task in a task tree and retrieve its test actions from TAB. A simulation environment was set up with a service robot model and a user model to test TAB and demonstrate some test actions. Simulations were also perfonned in this study, the simulation results proved TAB can successfully provide test actions according to different tasks and the proposed service robot model can demonstrate test actions

Locomoção bípede adaptativa a partir de uma única demonstração usando primitivas de movimento

Doutoramento em Engenharia EletrotécnicaEste trabalho aborda o problema de capacidade de imitação da locomoção humana através da utilização de trajetórias de baixo nível codificadas com primitivas de movimento e utilizá-las para depois generalizar para novas situações, partindo apenas de uma demonstração única. Assim, nesta linha de pensamento, os principais objetivos deste trabalho são dois: o primeiro é analisar, extrair e codificar demonstrações efetuadas por um humano, obtidas por um sistema de captura de movimento de forma a modelar tarefas de locomoção bípede. Contudo, esta transferência não está limitada à simples reprodução desses movimentos, requerendo uma evolução das capacidades para adaptação a novas situações, assim como lidar com perturbações inesperadas. Assim, o segundo objetivo é o desenvolvimento e avaliação de uma estrutura de controlo com capacidade de modelação das ações, de tal forma que a demonstração única apreendida possa ser modificada para o robô se adaptar a diversas situações, tendo em conta a sua dinâmica e o ambiente onde está inserido. A ideia por detrás desta abordagem é resolver o problema da generalização a partir de uma demonstração única, combinando para isso duas estruturas básicas. A primeira consiste num sistema gerador de padrões baseado em primitivas de movimento utilizando sistemas dinâmicos (DS). Esta abordagem de codificação de movimentos possui propriedades desejáveis que a torna ideal para geração de trajetórias, tais como a possibilidade de modificar determinados parâmetros em tempo real, tais como a amplitude ou a frequência do ciclo do movimento e robustez a pequenas perturbações. A segunda estrutura, que está embebida na anterior, é composta por um conjunto de osciladores acoplados em fase que organizam as ações de unidades funcionais de forma coordenada. Mudanças em determinadas condições, como o instante de contacto ou impactos com o solo, levam a modelos com múltiplas fases. Assim, em vez de forçar o movimento do robô a situações pré-determinadas de forma temporal, o gerador de padrões de movimento proposto explora a transição entre diferentes fases que surgem da interação do robô com o ambiente, despoletadas por eventos sensoriais. A abordagem proposta é testada numa estrutura de simulação dinâmica, sendo que várias experiências são efetuadas para avaliar os métodos e o desempenho dos mesmos.This work addresses the problem of learning to imitate human locomotion actions through low-level trajectories encoded with motion primitives and generalizing them to new situations from a single demonstration. In this line of thought, the main objectives of this work are twofold: The first is to analyze, extract and encode human demonstrations taken from motion capture data in order to model biped locomotion tasks. However, transferring motion skills from humans to robots is not limited to the simple reproduction, but requires the evaluation of their ability to adapt to new situations, as well as to deal with unexpected disturbances. Therefore, the second objective is to develop and evaluate a control framework for action shaping such that the single-demonstration can be modulated to varying situations, taking into account the dynamics of the robot and its environment. The idea behind the approach is to address the problem of generalization from a single-demonstration by combining two basic structures. The first structure is a pattern generator system consisting of movement primitives learned and modelled by dynamical systems (DS). This encoding approach possesses desirable properties that make them well-suited for trajectory generation, namely the possibility to change parameters online such as the amplitude and the frequency of the limit cycle and the intrinsic robustness against small perturbations. The second structure, which is embedded in the previous one, consists of coupled phase oscillators that organize actions into functional coordinated units. The changing contact conditions plus the associated impacts with the ground lead to models with multiple phases. Instead of forcing the robot’s motion into a predefined fixed timing, the proposed pattern generator explores transition between phases that emerge from the interaction of the robot system with the environment, triggered by sensor-driven events. The proposed approach is tested in a dynamics simulation framework and several experiments are conducted to validate the methods and to assess the performance of a humanoid robot

Humanoid Robots

For many years, the human being has been trying, in all ways, to recreate the complex mechanisms that form the human body. Such task is extremely complicated and the results are not totally satisfactory. However, with increasing technological advances based on theoretical and experimental researches, man gets, in a way, to copy or to imitate some systems of the human body. These researches not only intended to create humanoid robots, great part of them constituting autonomous systems, but also, in some way, to offer a higher knowledge of the systems that form the human body, objectifying possible applications in the technology of rehabilitation of human beings, gathering in a whole studies related not only to Robotics, but also to Biomechanics, Biomimmetics, Cybernetics, among other areas. This book presents a series of researches inspired by this ideal, carried through by various researchers worldwide, looking for to analyze and to discuss diverse subjects related to humanoid robots. The presented contributions explore aspects about robotic hands, learning, language, vision and locomotion

Producing Humans: An Anthropology of Social and Cognitive Robots

In this thesis, I ask how the human is produced in robotics research, focussing specifically on the work that is done to create humanoid robots that exhibit social and intelligent behaviour. Robots, like other technologies, are often presented as the result of the systematic application of progressive scientific knowledge over time, and thus emerging as inevitable, ahistorical, and a-territorial entities. However, as we shall see, the robot’s existence as a recognisable whole, as well as the various ways in which researchers attempt to shape, animate and imbue it ‘human-like’ qualities, is in fact the result of specific events, in specific geographical and cultural locations. Through an ethnographic investigation of the sites in which robotics research takes place, I describe and analyse how, in robotics research, robotics researchers are reflecting, reproducing, producing, and sometimes challenging, core assumptions about what it means to be human. The dissertation draws on three and a half years of ethnographic research across a number of robotics research laboratories and field sites in Ireland, the United Kingdom, and the United States between April 2016 and December 2019. It also includes an investigation of the sites where robotics knowledge is disseminated and evaluated, such as conferences and field test sites. Through a combination of participant and non-participant observation, interviews, and textual analysis, I explore how the robot reveals assumptions about the human, revealing both individual, localised engineering cultures, as well as wider Euro-American imaginaries. In this dissertation, I build on existing ethnographies of laboratory work and technological production, which investigate scientific laboratories as cultural sites. I also contribute to contemporary debates in anthropology and posthumanist theory, which question the foundational assumptions of humanism. While contemporary scholarship has attempted to move beyond the nature/culture binary by articulating a multitude of reconfigurations and boundary negotiations, I argue that this is done by neglecting the body. In order to address this gap, I bring together two complementary conceptual devices. First, I employ the embodiment philosophy of Maurice Merleau-Ponty (2012; 1968) particularly his emphasis on the body as a site of knowing the world. Second, I use the core anthropological concept of the ‘fetish’ as elaborated by William Pietz (1985). By interrogating the robot as ‘fetish’, I elaborate how the robot is simultaneously a territorialised, historicised, personalised, and reified object. This facilitates an exploration of the disparate, and often contradictory nature, of the relations between people and objects. In my thesis, I find many boundary reconfigurations and dissolutions between the human and the robot. However, deviating from the relational ontology dominant in the anthropology of technology, I discover an enduring asymmetry between the human and the robot, with the living body emerging as a durable category that cannot be reasoned away. Thus, my thesis questions how the existing literature might obscure important questions about the category of the human by focusing disproportionately on the blurring and/or blurred nature of human/non-human boundaries. Ultimately, I argue for a collaborative and emergent configuration of the human, and its relationship with the world, that is at once both relational and embodied. This dissertation is structured as follows. An initial introductory chapter is followed by a chapter documenting the literature review and conceptual framework. This is followed by four chapters that correspond to the four aspects of the fetish in Pietz’s model: Historicisation, Territorialisation, Reification and Personalisation. These chapters alternate between scholarly sources and ethnographic data. In Historicisation, using existing scholarship, I trace the history of the robot object, including the continuities and discontinuities that led to its creation, as well as the futures that are implicated in its identity. This is followed by the Territorialisation chapter, in which ethnographic data is used to interrogate the robot’s materiality, as well as the spaces in which it is built, modified, and tested. The next chapter, Reification, considers the robot as a valuable object according to institutions and the productive and ideological systems of Euro-American imaginaries. This chapter integrates ethnographic detail with existing scholarship to focus on contrasts between the dominant image of imminent super-human intelligence and the human interventions and social relationships necessary to produce the illusion of robot autonomy. Finally, the chapter Personalisation brings ethnographic attention to the intensely personal way that the robot-as-fetish is experienced in an encounter with an embodied person, understood through the lens of Merleau-Ponty’s embodiment philosophy. In the final chapter, I draw together the various strands to articulate how understanding the robot as a fetish, underscored by Merleau-Ponty’s embodiment phenomenology, can provide useful resources for developing an alternative understanding of the human in anthropology without dissolving it all together

Critique of Fantasy, Vol. 1

"Critique of Fantasy, Vol. 1: Between a Crypt and a Date Mark addresses both the style or genre of fantasy and the mental faculty, long the hot property of philosophical ethics. Freud passed it along in his 1907 essay on the poetics of daydreaming when he addressed omnipotent wish fantasy as the source and resource of the aspirations and resolutions of art, which, however, the artwork can never look back at or acknowledge. By grounding his genre in the one fantasy that is true, the Gospel, J.R.R. Tolkien obviated and made obvious the ethical mandate of fantasy’s restraining order. With George Lucas’s Star Wars we entered the borderlands of the fantasy and science fiction genres, a zone resulting from and staggering a contest, which Tolkien inaugurated in the 1930s. The history of this contested borderland marks changes that arose in expectation of what the new media held in store, changes realized (but outside the box of what had been projected) upon the arrival of the unanticipated digital relation, which at last seemed to award the fantasy genre the contest prize. Freud’s notion of the Zeitmarke (datemark), the indelible impress of the present moment that triggered the daydream that denies it, already introduced the import of fantasy's historicization. Science fiction won a second prize that keeps it in the running. No longer bound to projecting the future, the former calling which in light of digitization it flunked, science fiction becomes allegorical and reading in the ruins of its failed predictions illuminates all the date marks and crypts hiding out in the borderlands it traverses with fantasy. To motivate the import of an evolving science fiction genre, Critique of Fantasy makes Gotthard Günther's reflections in the 1950s on American science fiction – as heralding a new metaphysics and a new planetary going on interstellar civilization – a mainstay of its cultural anthropology with B-genres.

Miracle : the Pax Humana (Novel excerpt)

This thesis is an approximately 40,000 word-long excerpt of Miracle: The Pax Humana, a science fiction novel set in a "fallen-utopia" setting influenced by Golden Age science fiction, utopian literature of the Renaissance, John Milton's Paradise Lost, ancient Greek mythology, war poetry from WWI, and especially by the aesthetics of the emerging "Solarpunk" and "Hopepunk" subgenres of science fiction. Miracle itself focuses on the travels of interspecies diplomat Cleito Lyth- a human rescued and raised by the Chorus of Masks, a species of enigmatic yet peaceful aliens- as she undertakes a perilous journey to flee war-torn human space with a precious cargo in tow. Cleito's adventures across the shattered-yet-healing garden worlds of the Orion Arm allow Cleito and her companions to explore various ideas of what it truly means to be human—complicating Cleito’s increasingly dualistic (and often neurodivergent-coded) conceptions of identity, culture, and philosophy. Across Cleito’s growth as both a person and a human being, she must face the burning question of humanity's trajectory within their universe: are they architects of utopian wonder, or engines of apocalyptic horror? The work is an experiment in writing science fiction that shifts perspectives on tropes commonly used by space opera and/or military SF, using the premise of a “post-war” space opera setting to loosely explore topics of irenology, anthropology, human development, and long-term consequences of warfare. Meanwhile, cultural and technological remnants of the setting’s “Golden Age”/“Pre-war” era also allow for indirect exploration of optimistic futures relevant to contemporary “Solarpunk”/”Hopepunk” SF writers, without sacrificing the conflict and intrigue that often makes far-future SF settings so engaging to their audiences. This excerpt contains the Prologue and several chapters from the first "Act" of the novel, which introduces Cleito as a protagonist, establishes the themes and aesthetics of Miracle's post-war "Bloom", outlines exposition on the War, the post-war Turmoils, and some of the factions involved, and briefly introduces key characters within the broader story

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
