1. Uma aplicação de navegação robótica autônoma através de visão computacional estéreo / Autonomous application of robotic navigation using computer stereo vision
O presente trabalho descreve uma técnica de navegação autônoma, utilizando imagens estereoscópicas de câmeras para estimar o movimento de um robô em um ambiente desconhecido. Um método de correlação de pontos em imagens unidimensionais é desenvolvido para a identificação de pontos homólogos de duas imagens em uma cena. Utilizam-se métodos de s

2. Outdoor mapping using mobile robots / Mapeamento de ambientes externos utilizando robôs móveis
Autonomous mobile robotics is a recent research area that focus on the construction of mechanisms capable of executing tasks without a human control. In general, mobile robotics deals with three fundamental problems: environment mapping, robot localization and navigation. Without these elements, the robot hardly could move autonomously from a place to anothe

3. Controle de movimentos coordenados de robôs móveis quando os robôs assumem a liderança de maneira aleatória / Control of coordinated movements of mobile robots when the robots take the lead in a random
This dissertation proposes a study on the automatic control of dynamic systems to the problem of coordination of mobile robots. The coordinated motions are performed with the robots following a leader, and any robot of the formation can assume the leadership randomly. The robots exchange informations according to a pre-specified communication directed graph

4. COMPARAÇÃO ENTRE CONTROLES LOOK-AND-MOVE E SERVO-VISUAL UTILIZANDO TRANSFORMADAS SIFT EM MANIPULADORES DO TIPO EYE-IN-HAND / COMPARISON BETWEEN LOOK-AND-MOVE AND VISUAL SERVO CONTROL USING SIFT TRANSFORMS IN EYE-IN-HAND MANIPULATOR SYSTEMS
Computer vision can be used to calibrate and self-localize robots. There are many applications in self-localization and control applied to industrial manipulators and mobile robots. In particular, visual control can be useful in submarine interventions, where a robotic manipulator is mounted on a Remote Operated Vehicle (ROV) to execute tasks at high depths,

9. 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
