2. Plataforma de software para técnicas de navegação e colaboração de robôs móveis autônomos / Software platform for autonomous mobile robot navigation and collaboration
The navigation and collaboration are important aspects of mobile robotics. The navigation provides to mobile robots the basic skills of interaction with the environment, and the obstacles and agents located therein. The collaboration allows the robots to coordinate their navigation and interaction with the environment in a way that enables them to per-form c

4. 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

6. Uma proposta de controle neural adaptativo para a navegação de veículos autônomos / Autonomous vehicle navigation control: an adaptative neural networks proposal
Os equipamentos robóticos foram inicialmente criados para atuarem em ambientes industriais fechados. Com o passar do tempo, melhorias foram conquistadas. Atualmente, não se limitam mais à realização de tarefas simples e repetitivas em locais especialmente preparados. Novos equipamentos, capazes de atuarem em ambientes abertos e de realizarem as mais div

7. 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

8. Active system of auto-stabilization for suspended vehicles. / Sistema ativo de auto-estabilização para veículos suspensos.
During the last decades, many researches and studies have been done about suspended vehicles such as chair lifts, cable cars, carrying and assemblies of parts in the industry, etc. Suspended vehicles behave like a pendulum and they are susceptible to the action of external forces which cause oscillations and unwanted swing at the vehicle that may affect func

11. 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

12. Estimação de posição e quantificação de erro utilizando geometria epipolar entre imagens. / Position estimation and error quantification using epipolar geometry between images.
Position estimation is the direct result of scene reconstruction, one of computer visions fields. It is also an important information for the control of mechanical systems - specially the autonomous robotic systems. As an engineering application, those systemsperformance must be evaluated in terms of efficiency and effectiveness, measured by processing costs
