25. Técnica de Navegação de um Robô Móvel Baseado em um Sistema de Visão para Integrá-lo em uma Célula Flexível de Manufatura (FMC) / Mobile robot navigation technique based in vision system for integrate it to a flexivel manufacturing cell (FMC)
Nowadays, the control of the automatic guided vehicles (AGV), is based on the study of different navigation existing techniques. Those utilize different kinds of sensors (infrared, ultrasound, tactile, vision, etc) as part of the equipment included in the mobile robot carrying out their tasks of movement and control since an initial position to a defined fin

26. Aprendizagem por reforço na adaptação a obstáculos em navegação robótica autônoma não-estruturada baseada em imagens / Reinforcement learning for obstable avoidance in image based robotic autonomous non-structured navigation
In the last decades, robotic has become an important role for society, specially in the manufacturing industry. In recent times, applications of mobile robots, from simple toys to planets explorations, has shown how promising will be the use of these tools in a close future. Though, the cost and complexity in developing mobile robots nowadays, which should b

27. Polinomial curves estimation in image sequences to mobile robot navigation / Estimação de curvas polinomiais em sequências de imagens para navegação de robôs móveis
Neste trabalho, foi implementado um sistema de visão computacional para navegação de robôs móveis baseado em rastreamento de trajetórias. Essas trajetórias são formadas por marcas artificiais adicionadas ao teto do ambiente na forma de curvas e retas. Para marcar o teto foram utilizadas cordas e fita adesiva escuras fixadas ao teto formando retas e c

28. Posicionamento e movimentação de um robô humanóide utilizando imagens de uma câmera móvel externa
This work proposes a method to localize a simple humanoid robot, without embedded sensors, using images taken from an extern camera and image processing techniques. Once the robot is localized relative to the camera, supposing we know the position of the camera relative to the world, we can compute the position of the robot relative to the world. To make the

29. Agente topológico de aprendizado por reforço / Topological reinforcement learning agent
Reinforcement Learning (RL) methods have shown to be a good choice for decision-making problems due to their flexible and adaptive characteristics. Despite such promising features, RL methods often have their practical application restricted to small or medium size (at state, or state-action, space) problems mainly because of their standard strategies for va

31. Uma proposta evolutiva para controle inteligente em navegação autonoma de robos
This work presents an autonomous evolutionary system applied to the control of a mobile robot when navigating in unknown environments. The system is reactive, it does not have initial knowledge and learns efficiently to deal with situations where the robot must capture targets avoiding collisions against obstacles. Toward this end, it develops general strate

32. Evidence grids with omnidirectional stereovision for mobile robots. / Grades de evidência com visão estéreo omnidirecional para robôs móveis.
Autonomous mobile robots depend on information acquired with its sensors to make decisions during its task. The use of vision systems provide a large amount of data about the environment in which the robot is. Particularly, an omnidirectional vision systems provide information in all directions of the environment to the robot with just one image. Through the

33. Map building for mobile robot navigation with omnidirectional stereo vision. / Construção de mapas de ambiente para navegação de robôs móveis com visão omnidirecional estéreo.
O problema de navegação de robôs móveis tem sido estudado ao longo de vários anos, com o objetivo de se construir um robô com elevado grau de autonomia. O aumento da autonomia de um robô móvel está relacionado com a capacidade de aquisição de informações e com a automatização de tarefas, tal como a construção de mapas de ambiente. Sistemas d

34. Navegação e controle de robôs móveis cooperativos: uma abordagem baseada em conectividade de grafos
This thesis addresses the problem of motion planning and control of groups of autonomous mobile robots during cooperative tasks execution. A general framework that transforms several cooperative tasks into the same basic problem is developed thus providing a feasible solution for all of them. The approach enables using a single team of robots to perform nume

35. A Test Bed Applied Mobile Robot Navigation
It is presented a test bed applied to studies on dynamics, control, and navigation of mobile robots. A cargo ship scale model was chosen, which can be radio-controlled or operated autonomously through an embedded control system. A control program, which manages on board mission execution, is implemented on a microcontroller. Navigation is based on an electro

36. Geração de trajetorias para robos moveis autonomos via redes neurais artificiais
The autonomous navigation of vehic1es has been an area of great interest for researchers for a long time, mainly in the area of artificial intelligence. One of the most interesting problems is that related to the trajectory generated for a vehic1e, which shall be guided in an environrnent, avoiding colliding with obstac1es in order to reach predefined positi
