3. ACID: arquitetura de controle para integração de dispositivos / ACID: control architecture for device integration
O objetivo desta tese é adaptar um modelo de integração industrial baseado no protocolo de comunicação XML Interface for Robots and Peripherals (XIRP), de modo que este pudesse ser aplicado à realidade de pequenas e médias empresas brasileiras (PMEs). Para que isto fosse possível, é necessário estudar os ambientes industriais existentes e a complex

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,

6. CALIBRAGEM VISUAL IN SITU DE MANIPULADORES ROBÓTICOS COM APLICAÇÃO EM INTERVENÇÕES SUBMARINAS / VISION BASED IN-SITU CALIBRATION OF ROBOTS WITH APPLICATION IN SUBSEA INTERVENTIONS
The majority of today`s industrial robots are programmed to follow a predefined trajectory. This is sufficient when the robot is working in a fixed environment where all objects of interest are situated in a predetermined position relative to the robot base. However, if the robot`s position is altered all the trajectories have to be reprogrammed for the robo

7. Contribuição ao planejamento de trajetória de robôs através de elementos de dinâmica, controle e otimização / Contribution to robot path planning through dynamics, control and optimization
Robotic manipulators are programmable devices designed to execute a great variety of tasks in a repetitive way. In industrial environments, the reduction of dynamic requirements associated to a specific task can result in productivity increase and cost reduction regarding the robotic operation and maintenance. Moreover, the reduction of such requirements can

9. Influência do comportamento estrutural no erro de posicionamento de uma máquina de cinemática paralela. / Influence of the structural behavior in the error of positioning of a parallel kinematic machine.
In spite of the effort spent by the academic and industrial communities (goods, patents and laboratory prototypes), the Parallel Kinematics Machines - PKMs - they still present an inexpressive participation in the market of machine-tools and robots. One of the reasons for this fact is their low indexes of accuracy and precision, in comparison with the machin

10. Modelagem e otimização de um robô de arquitetura paralela para aplicações industriais. / Modeling and optimization of a parallel architecture robot for industrial applications.
This work is about the study of parallel architecture robots, focusing in modeling and optimization. No physical prototypes were built, although the virtual models can help those willing to do so. After searching for an application that could benefit from the use of a parallel robot, another search was made, this time for the right architecture type. After s

12. Variable structure position control of an industrial robotic manipulator
The use of a robust position controller for a robotic manipulator moving in free space is presented. The aim is to implement in practice a controller that is robust to uncertainties in the model of the system, as well as being inexpensive from a computational point of view. Variable structure theory provides the technique for the design of such controller. T
