25. 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

28. 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

29. Uma contribuição ao desenvolvimento de manipuladores antropomorficos com enfase na utilização de musculos artificiais / A contribution to the development of anthropomorphic manipulators with emphasis in the use of artificial muscles
Este trabalho visou o estudo de manipuladores à semelhança do membro superior humano. Após o estudo do membro superior humano e dos robôs antropomórficos disponíveis tanto na industria quanto no meio acadêmico, utilizaram-se teorias de modelagem geométrica, cinemática direta e cinemática inversa para realizar o modelo de um manipulador robótico an

30. Hyper-redundant robots with modules of parallel arquitecture. / Robô hiper-redundante com módulos de arquitetura paralela.
This research studies hyper-redundant robots focusing on the kinematics analysis. A hyper-redundant robot was developed based on modules of parallel architecture and binary actuators. Each module has three degrees-of-freedom, two rotational degrees of freedom with perpendicular axis and one translational degree of freedom. After searching for parallel struct

31. 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

34. Virtual kinematic chains to solve the underwater vehicle-manipulator systems redundancy
This paper addresses the kinematics of the Underwater Vehicle-Manipulator Systems (UVMSs). Due the adittional degrees of freedom (dofs) provided by the vehicle, such systems are kinematically redundant, i.e. they possess more dofs than those required to execute a given task, and need to be solved using some redundancy technique. We present an approach based

35. DEVELOPMENT OF A THREE DEGREE-OF-FREEDOM PNEUMATIC LINK FOR FLEXIBLE ROBOTIC MANIPULATORS / DESENVOLVIMENTO DE UM ELO PNEUMÁTICO DE 3 GRAUS DE LIBERDADE PARA MANIPULADORES ROBÓTICOS FLEXÍVEIS
Recently, the concept of flexible manipulators has attract great interest. These devices present a continuously deforming vertebral column, in opposition to the traditional robotic manipulators link/joint/link with rigid links. Flexible systems offer a potential increase in the capacity of interaction with the environment, being apt to adjust itself to the c

36. 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
