15. 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,

16. Comportamento de líquidos no espaço-sloshing e amortecedores de nutação viscosos / Fluid behavior in the space-sloshing and viscous nutation dampers
The attitude dynamics refers to the space vehicle motion around its center of mass while orbiting the Earth. The knowledge of the attitude motion is fundamental for the accomplishment of the space mission objectives. The use of appropriate sensors and actuators, onboard computers, GPS and radars and ground stations are among technologies allowing the attitud

17. Telescopic continuum robot for tasks at high positions. / Robô contínuo telescópico para tarefas em alturas elevadas.
Among several applications of robots in the service field, it is possible to percept an increasing interest in manipulate tools in higher positions using automatic devices, due to the fact that such activities are high risked operations and demands the use of several safety equipments. The most common examples of this kind of activity are the inspection of m

18. A fault detection and isolation system for cooperative manipulators
The problem of fault detection and isolation (FDI) in cooperative manipulators is addressed in this paper. Four FDI procedures are developed to deal with free-swinging joint faults, locked joint faults, incorrectly measured joint position, and incorrectly measured joint velocity. Free-swinging and locked joint faults are isolated via neural networks. For eac

24. CARACTERIZAÇÃO DE ATUADORES BASEADOS EM MÚSCULOS ARTIFICIAIS POLIMÉRICOS POR EFEITO CAPACITIVO / CHARACTERIZATION OF ACTUATORS BASED ON POLYMERIC ARTIFICIAL MUSCLES WITH CAPACITIVE EFFECT
It is well known the needs of finding new technologies for robotic systems actuations, with the same efficiency of the natural muscles. The common actuators have better agility and force when compared to natural muscles, but the dimensions and weight are bigger and for that the demand of energy necessary for the actuation is higher. Smaller and cheaper robot
