13. An approach to avoid obstacles in mobile robot navigation: the tangential escape
An approach to guide a mobile robot from an initial position to a goal position avoiding any obstacle in its path, when navigating in a semi-structured environment, is proposed in this paper. Such an approach, hereinafter referred to as tangential escape, consists in changing the current robot orientation through a suitable combination of the values of the a

14. Synthesis of autonomous controllers in mobile robotics through bio-inspired computing / Sintese de controladores autonomos em robotica movel por meio de computação bio-inspirada
Novel techniques for autonomous robot navigation aim at fulfilling the growing demand for mobile robots in multiple segments of society and in a plethora of tasks. The challenges involved in developing the system which controls the robot allow to say that the intelligence embedded in the current robots is found to be still incipient and limited. In this work

15. Auto-localização e construção de mapas de ambiente para robôs móveis baseados em visão omnidirecional estéreo. / Simultaneous localization and map building for mobile robots with omnidirectional estereo vision.
This project aims the development of a system for self localization and environment map building for mobile robots in a structured environment. The map is built from images acquired by an omnidirectional stereo system with a hyperbolic double lobed mirror. From a single acquired image, using stereo vision algorithms, the environment around the robot is tridi

17. An optical flow-based sensing system for reactive mobile robot navigation
This work discusses the use of optical flow to generate the sensorial information a mobile robot needs to react to the presence of obstacles when navigating in a non-structured environment. A sensing system based on optical flow and time-to-collision calculation is here proposed and experimented, which accomplishes two important paradigms. The first one is t

18. 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

20. 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
