25. Ambiente de desenvolvimento de aplicações para robôs móveis / Environment for development applications for mobile robots
Recent advances in the technology of mobile robots have developed for a new type of robotic system which is named personal robot. These robots are able to realize domestic daily tasks, interact and help people with special cares. In order to perform such tasks, interaction and programming measurements between the robot and the human being are necessary. This

26. Uma arquitetura distribuída de hardware e software para controle de um robô móvel autônomo
In this work, we present a hardware-software architecture for controlling the autonomous mobile robot Kapeck. The hardware of the robot is composed of a set of sensors and actuators organized in a CAN bus. Two embedded computers and eigth microcontroller based boards are used in the system. One of the computers hosts the vision system, due to the signiᤙ

28. 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

29. TIP OVER AND SLIPPAGE CONTROL OF MOBILE ROBOTIC SYSTEMS OVER ROUGH TERRAIN / CONTROLE DE CAPOTAGEM E DESLIZAMENTO DE SISTEMAS ROBÓTICOS MÓVEIS EM TERRENOS ACIDENTADOS
The use of mobile robots to monitor non-accessible environments has become increasingly common in the recent years. These tasks can be either autonomous, remote-controlled, or passenger-operated. When performed in rough terrain, it is necessary to guarantee mission safety, since many times it is impossible to send a rescue party for recovery. The hybrid envi

32. 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

34. 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

36. Contribuição ao planejamento de trajetória de robôs através de elementos de dinâmica, controle e otimização / Contribution to robot path planning through dynamics, control and optimization
Robotic manipulators are programmable devices designed to execute a great variety of tasks in a repetitive way. In industrial environments, the reduction of dynamic requirements associated to a specific task can result in productivity increase and cost reduction regarding the robotic operation and maintenance. Moreover, the reduction of such requirements can
