13. Um sistema de visão para navegação robusta de uma plataforma robótica semi-autônoma
Large efforts have been maden by the scientific community on tasks involving locomotion of mobile robots. To execute this kind of task, we must develop to the robot the ability of navigation through the environment in a safe way, that is, without collisions with the objects. In order to perform this, it is necessary to implement strategies that makes

14. Autonomous robot s navigation based on monocular vision / Navegação de robos autonomos baseada em monovisão
Neste trabalho apresentamos um sistema autônomo baseado em monovisão, aplicado ao controle de um robô móvel em tarefas de navegação por ambientes desconhecidos. Para o cumprimento de tarefas de navegação, o sistema não possui conhecimento inicial sobre o ambiente, tendo como fonte primária de informações, dados oriundos do sistema de visão. Os m

15. Robô agrícola móvel (RAM): uma arquitetura baseada em comportamentos hierárquicos e difusos para sistemas autônomos de guiagem e navegação / Agricultural mobile robot (MAR): an architecture based on hierarchical and fuzzy behaviors for autonomous systems of guidance and navigation
Avanços positivos nas pesquisas em veículos agrícolas autônomos (VAAs) e de robôs agrícolas móveis (RAMs) têm sido conquistados nos últimos anos. Entretanto, um número limitado de trabalhos tem proposto sistemas robustos baseados em arquiteturas robóticas capazes de realizar operações múltiplas e idependentes, bem como adaptar-se às mudanças

16. 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

18. 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

19. 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

20. 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

21. Speed Control of an Autonomous Mobile Robot: Comparison between a PID Control and a Control Using Fuzzy Logic
An Autonomous Mobile Robot battery driven, with two traction wheels and a steering wheel is being developed. This Robot central control is regulated by an IPC, which controls every function of security, steering, positioning localization and driving. Each traction wheel is operated by a DC motor with independent control system. This system is made up of a ch

22. 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

23. Estudo sobre robos de locomoção : formas construtivas, dirigibilidade e controle
The objective of this work is to study the constructive forms more viable to build an autonomous vehicle for people with some physical deficiency. This vehicle will be called as mobile robot, because the vehicle s results can be applied to this type of robots. Initially an introduction to main driven forms applied to mobile robots and the study of tires moti
