13. Localização e mapeamento simultâneos com auxílio visual omnidirecional. / Simultaneous localization and mapping with omnidirectional vision.
The problem of simultaneous localization and mapping, known as the problem of SLAM, is one of the greatest obstacles that the field of autonomous robotics faces nowadays. This problem is related to a robots ability to navigate through an unknown environment, constructing a map of the regions it has already visited at the same time as localizing itself on thi

14. On cognition, adaptation and homeostasis : analysis and synthesis of bio-inspired computational tools applied to robot autonomous navigation / Sobre cognição, adaptação e homeostase : uma analise de ferramentas computacionais bioinspiradas aplicadas a navegação autonoma de robos
The objectives of this work are to study, develop and apply two bio-inspired computational tools in robot autonomous navigation. The first tool is represented by Learning Classifier Systems, using the strength-based and the accuracy-based models. Additionally, the rule evolution mechanisms and the final evolved populations are analyzed. The second tool is a

15. Geração de trajetórias para veículos aéreos autônomos não-tripulados
In this work a study on the problem of the trajectory generation for unmanned aerial vehicles is carried through. The main objective is to provide tools of path planning for aerial robots, taking into account some of its main physical constraints of movement. For this, some of the more used techniques for motion planning of grounded robots are argued initial

16. Arquitetura híbrida inteligente para navegação autônoma de robôs / Intelligent hybrid architecture for robot autonomous navigation
This project consists in a autonomous navigation system based on modular neuro-fuzzy networks that is able to guide the robot in unknown environments from a initial point to the goal. Initially, the system is not able to navigate, but after a trial and error period and some collisions, it improves in guiding the robot to the goal efficiently. A intelligent h

18. 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

19. 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
