1. DESIGN AND EXPERIMENT OF A SAFFLOWER PICKING ROBOT BASED ON A PARALLEL MANIPULATOR
ABSTRACT To mitigate the large demand for safflower picking labour and the low efficiency of manual picking, a safflower picking robot that is based on a parallel manipulator is designed. The whole robot mainly consists of a walking device, parallel manipulator device, vision device, picking device, filament collection device, control system, and motor drive

2. Structure Comparison and Optimal Design of 6-RUS Parallel Manipulator Based on Kinematic and Dynamic Performances
Abstract The effects of distinctive parameters such as revolute joint angle or spherical joint location of mobile platform in a 6-DOF 6-RUS parallel manipulators on workspace, kinematic, and dynamic indices are investigated in this study to select proper structure commensurate with performance. Intelligent multi-objective optimization method is used to desig

3. Application of H∞ theory to a 6 DOF flight simulator motion base
The purpose of this study is to apply inverse dynamics control for a six degree of freedom flight simulator motion system. Imperfect compensation of the inverse dynamic control is intentionally introduced in order to simplify the implementation of this approach. The control strategy is applied in the outer loop of the inverse dynamic control to counteract th

4. Analysis of kinematic, kinetic and electromyographic patterns during root canal preparation with rotary and manual instruments
OBJECTIVE: This study assessed the muscular activity during root canal preparation through kinematics, kinetics, and electromyography (EMG). MATERIAL AND METHODS: The operators prepared one canal with RaCe rotary instruments and another with Flexo-files. The kinematics of the major joints was reconstructed using an optoelectronic system and electromyographic

5. Modelagem dos movimentos funcionais robótico-assistidos para a reabilitação dos membros superiores: redução dos graus de liberdade de um manipulador antropomórfico / Functional Movement Modeling for robot-assisted upper
A reabilitação robótica é uma ciência que permite o desenvolvimento de dispositivos ativos para vários processos no campo da saúde. No caso da reabilitação, substitui a assistência física por um dispositivo robótico, sob a supervisão do terapeuta. Segundo alguns autores, há muitas evidências de que os movimentos repetitivos podem ajudar na rea

7. Análise da influência de um calçado flexível e desprovido de salto sobre a mecânica da marcha e a carga articular de indivíduos com osteoartrite de joelho / Influence of flexible footwear and without heel on the gait mechanics and joint loading in individuals with knee osteoarthritis
The literature has been given evidences that the use of flexible and non-heeled footwear that reproduces the kinematic and kinetic characteristics of barefoot gait may reduce the joint loads and the progression of the knee osteoarthritis (OA). The purpose of this study was to evaluate and compare the influence of the acute use of flexible, non-heeled and ine

8. Desenvolvimento de dobras e falhas em ambiente distensional: Aplicação da modelagem física
The geological modeling allows, at laboratory scaling, the simulation of the geometric and kinematic evolution of geological structures. The importance of the knowledge of these structures grows when we consider their role in the creation of traps or conduits to oil and water. In the present work we simulated the formation of folds and faults in extensional

9. 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

10. 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
