1. Image matching and classification for UAV navigation.
Unmanned aerial vehicles, known as UAVs, have evolved over the past two decades to sophisticated aircraft robots able to carry out surveillance, recognition, remote sensing and even attack missions. But there are not many alternatives of autonomous navigation systems for most of these aircraft which still require human intervention to navigate. Devices such

2. On-line SLAM using clustered landmarks with omnidirectional vision
The problem of SLAM (simultaneous localization and mapping) is a fundamental problem in autonomous robotics. It arises when a robot must create a map of the regions it has navigated while localizing itself on it, using results from one step to increase precision in another by eliminating errors inherent to the sensors. One common solution consists of establi

3. Mapeamento e localização simultâneos para multirobôs cooperativos. / Cooperative multi-robot simultaneous localization and mapping.
Neste trabalho foi desenvolvido um estudo comparativo entre duas estratégias básicas para a combinação de mapas parciais baseados em marcos para sistemas multirobô: a estratégia por associação de marcos e a estratégia por distância relativa entre os robôs (também conhecida por rendez-vous). O ambiente simulado corresponde a um entorno plano povoa

4. 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

5. Hardware/Software codesign of particle filter for real time localization of mobile robots / Co-projeto de hardware/software do filtro de partículas para localização em tempo real de robôs móveis
Sophisticated techniques for estimation of models based on simulation, particle filters or Sequential Monte Carlo Methods, were recently used to solve many difficult problems in the field of mobile robotics. However, the success of particle filters was limited to the computation of parameters in low dimensionality spaces. The current research efforts in mobi

6. Módulo de auto-localização para um agente exploratório usando Filtro de Kalman / Self-localization module for exploratory agent using kalman filter
Construir um robô capaz de realizar tarefas sem qualquer interferência humana é um dos maiores desafios da Robótica Move!. Dispondo apenas de sensores, um robô autônomo precisa explorar ambientes desconhecidos e, simultaneamente, construir um mapa confiável a fim de se localizar e realizar a tarefa. Na presença de erros de odometria, o robô não con

8. An improved particle filter for sparse environments
In this paper, we combine a path planner based on Boundary Value Problems (BVP) and Monte Carlo Localization (MCL) to solve the wake-up robot problem in a sparse environment. This problem is difficult since large regions of sparse environments do not provide relevant information for the robot to recover its pose. We propose a novel method that distributes pa

9. Adaptive complementary filtering algorithm for mobile robot localization
As a mobile robot navigates through an indoor environment, the condition of the floor is of low (or no) relevance to its decisions. In an outdoor environment, however, terrain characteristics play a major role on the robot's motion. Without an adequate assessment of terrain conditions and irregularities, the robot will be prone to major failures, since the e

10. General detection model in cooperative multirobot localization
The cooperative multirobot localization problem consists in localizing each robot in a group within the same environment, when robots share information in order to improve localization accuracy. It can be achieved when a robot detects and identifies another one, and measures their relative distance. At this moment, both robots can use detection information t

11. Appearance-based odometry and mapping with feature descriptors for underwater robots
The use of Autonomous Underwater Vehicles (AUVs) for underwater tasks is a promising robotic field. These robots can carry visual inspection cameras. Besides serving the activities of inspection and mapping, the captured images can also be used to aid navigation and localization of the robots. Visual odometry is the process of determining the position and or

12. 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,
