2. 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

3. Optimal trajectory planning of robots with parallel structure / Otimização de trajetórias de robôs com estrutura paralela
Parallel manipulators are of great interest mainly because they present advantages in several applications, showing great resistance, positioning accuracy, load capacity larger than serial manipulators and they can be operated to high-speeds and accelerations. In the Laboratory of Robotics and Mechatronics in Casino, Italy, a parallel mechanism was created w

4. A new robotic drive joint friction compensation mechanism using neural networks
The knowledge of realistic dynamic models to robotic actuators would be of great aid in the synthesis of control laws to robot manipulators, mainly in cases of great precision robotic or even for manipulators with flexible links. In this paper we present a training scheme and propose a structure of neural network (NN) to learn the friction torque of a geared

5. Projeto de atuadores piezelétricos flextensionais usando o método de otimização topológica. / Design of flextensional piezoelectric actuator using the topology optimization method.
Flextensional Piezoelectric Actuators consist of a flexible structure actuated by piezoelectric ceramics (or a stack of piezoceramics). The flexible structure connected to the piezoceramic must generate displacements and forces in different specified points of the domain, according to a specific direction. These actuators are applied to precision mechanic ap

6. Dinâmica e controle de movimento de corpo rígido de um manipulador robótico rígido/flexivel / Dynamic and control of rigid body motion of a rigid/flexible robotic manipulador
This work presents a study of the dynamics and control of the movement of rigid body of a robotic manipulator. The model of the manipulator, consisting of a mechanism with two flexible links hardwired by meetings that do not suffer deformations, was gotten through the Formularization of Lagrange and the Admitted Modes Method. For matching effect, two other m
