Menges, Baptiste. "Étude d’un système robotique coopératif en milieu sidérurgique sévère." Electronic Thesis or Diss., Université de Lorraine, 2021. http://www.theses.fr/2021LORR0261.
The work proposed as part of this thesis is part of improving the production quality and working conditions of Saint-Gobain PAM steel sites. It was proposed to study and develop a collaborative robotic system capable of assisting an operator in repetitive, painful and sometimes dangerous tasks in an environment of extreme heat and dust. Recently passed CMR, crystalline silica dust represents the biggest problem requiring the study of alternative solutions to current production methods.More specifically, the operator's workstation, which is critical for the quality of production, requires demanding attention and know-how. The operator's job is to monitor, clean, coat, maintain a cast iron casting member of a centrifuge machine used in the production of ductile iron pipe. Many movements made by the operator are characterized as rhythmic and form a closed limit cycle, the same behavior of which is observed in dynamic oscillators.The objective of this thesis is therefore to study an alternative solution to reduce operator exposure. The technological choice fell on the remote operation of a robotic system in order to reproduce the tasks remotely outside the exhibition areas. The control of these rhythmic tasks will be carried out by different models of oscillator and different means of teleoperation. This thesis will also aim to study the implementation of two dynamic oscillators, those of Hopf and Rowat-Selverston coupled to three different teleoperation devices.Thanks to the various tests, we observed the impact of a control with a dynamic oscillator compared to a control without. We can also observe the impact that the various remote operation devices may have on the control signals

O propósito da Visão Computacional consiste em permitir que um robô entenda o ambiente em que se situa a partir de informações visuais. O mundo no qual robôs se movem é tridimensional e dinâmico. Ele se altera em função do próprio movimento do robô e do movimento dos demais objetos. A presente dissertação descreve a implementação de sistema robótico autômato, que utiliza visão para alcançar objetivos predeterminados. Consiste, essencialmente, em um robô que carrega consigo uma câmera de vídeo. Esta câmera transmite as imagens capturadas, por rádio, para um microcomputador à distancia. Este microcomputador processa a imagem e retorna ao robô (também por rádio) os comandos referentes a que trajetória deve ser seguida. Este processo ocorre sucessivamente até alcançar-se o objetivo pré-determinado. A característica multidisciplinar do presente projeto de pesquisa reúne três áreas distintas do conhecimento, sendo elas, mecânica, eletrônica (linear e digital) e processamento digital de imagens. Descreve-se a implementação de cada área isoladamente e de que forma são integradas a fim de formar um sistema único.
The aim of Computer Vision is to allow a robot to understand the surrounding environment, with acquired visual information as input. The environment in which the robot moves is three-dimensional and dynamic and modifies as a function of its own movement of surrounding objects. The presente dissertation describes an automaton robotic system which makes use of computer vision to achieve some predetermined goals. Essentially, it consists of a robot that carries a video camera. The camera transmits radio captured images to a remote micromputer. In turn, the microcomputer processes the image and sends the commands back to the robot, by radio, to indicate the path that should be followed. This process is repeated until the predetermined goal has been achieved. This multi-disciplinary project tackles three different research areas, mechanics, eletronics (linear and digital) and image processing. Each parte of the project is thouroughly described as is also the integration of ecah to form a sole system.

The NCS (NeoCortical Simulator) is a neural network simulator that can simulate small brains in real time. Since brains learn by interacting with the world, we created the NeoCortical Virtual Robot framework, which allows researchers to build virtual worlds for simulated brains to interact with, by supplying scientists with a domain-specific language for interaction and abstractions for environment creation.

Experiments on real-world data are conducted under different configurations to demonstrate the feasibility of the method. In particular, our application is in mobile robotics, where inferring the 3D layout of indoor environments is a critical problem for achieving exploration and navigation tasks. The modeling of a large-scale environment involves the acquisition of a huge amount of range data to extract the geometry of the scene, and is often performed using sophisticated but costly hardware solutions. This task is physically demanding and time consuming for many real systems. By using the proposed framework, it is demonstrated that we can learn the geometric characteristics of the environment from the incomplete sensory data to build a 3D model of it.
The contributions of this thesis are mainly three: First, it demonstrates the viability of the use of very limited range data together with intensity to recover complete dense range maps. Second, it presents a complete framework for building a 3D model of an indoor environment using a mobile robot. And third, it analyses and outlines the advantages and limitations encountered when dealing with large indoor environments.
An additional contribution is the use of the method we propose for range estimation to an alternative problem: color correction and augmentation with the specific application to underwater images.

Algeria is widely recognized, particularly by international organizations, as being hostile to private entrepreneurship. Through the observation of several private companies that are prosperous in this country, we wanted to understand and explain their success despite this hostile context. A qualitative study based on the examination of multiple cases allows us to shed light on the levers of these successes (Novo Nordisk, Tifra-Lait, NCA-Rouiba, Cevital, etc.). It emerges from this research that managerial innovation seems to be one of the key elements of these successes. Moreover, this study has enabled us to understand the importance of resilience, particularly that of the creators and managers of these companies. Indeed, the research shows that, in the cases we consider, managerial innovation favors resilience by allowing to better seize certain opportunities and to face the hostile environment towards private entrepreneurship

Sexual harassment in the workplace continues to be experienced by many women around the world. Men may also be sexually harassed in the workplace by women or by other men. Given the pronounced attention accorded over the last few months to high ranking individuals within South Africa and the USA who have allegedly been involved in incidences of sexual harassment, the study is timely. The focus of sexual harassment studies within the workplace is furthermore important as it affects the employees, employers and the workplace as a whole. The purpose of the present study was to investigate the experiences and perceptions of sexual harassment of employees of an information technology company. Information technology has typically been a male dominated occupation, and prevailing traditional, paternalistic attitudes may adversely impact on women's choice and pursuit of a career in this field. However, South African legislation, promulgated to enhance the intake of women and marginalised groups, has sought to strengthen gender equality and, concomitantly, the participation of women in information technology. The current research was conducted by administering the Sexual Harassment Experience Questionnaire and Perception of Sexual Harassment Questionnaire to a sample of 131 employees. These questionnaires were distributed via email within one organisation and four regional branches of the same organisation.

Personal robots associated with ambient intelligence are an upcoming solution for domestic care. In fact, helped with devices dispatched in the environment, robots could provide a better care to users. However, such robots are encountering challenges of perception, cognition and action.In fact, such an association brings issues of variety, data quality and conflicts, leading to the heterogeneity and uncertainty of data. These are challenges for both perception, i.e. context acquisition, and cognition, i.e. reasoning and decision making. With the knowledge of the context, the robot can intervene through actions. However, it may encounter task failures due to a lack of knowledge or context changes. This causes the robot to cancel or delay its agenda. While the literature addresses those topics, it fails to provide complete solutions. In this thesis, we proposed contributions, exploring both reasoning and learning approaches, to cover the whole spectrum of problems. First, we designed novel context acquisition tool that supports and models uncertainty of data. Secondly, we proposed a cognition technique that detects anomalous situation over uncertain data and takes a decision in accordance. Then, we proposed a dynamic planner that takes into consideration the last context changes. Finally, we designed an experience-based reinforcement learning approach to proactively avoid failures.All our contributions were implemented and validated through simulations and/or with a small robot in a smart home platform
