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. 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

3. ANÁLISE DE DESEMPENHO EM TRAÇÃO DE RODADO SIMPLES E DUPLO EM UM TRATOR AGRÍCOLA / ANALYSIS OF TRACTION PERFORMANCE OF SINGLE AND DUAL TIRES IN AN AGRICULTURAL TRACTOR
A major problem of agricultural tractor during several operations in which it is used is the difficulty of working in various moisture conditions and soil types affect your ability to traction force, slip and fuel consumption. What has been observed is that with increased contact surface between the tire of the tractor and the ground, there is the possibilit

4. Desenvolvimento de Uma Órtese Ativa Para os Membros Inferiores Com Sistema Eletrônico Embarcado
This work presents the development of a prototype of an intelligent active orthosis for lower limbs whit an electronic embedded system. The proposed orthosis is an orthopedical device with the main objective of providing walking capacity to people with partial or total loss of lower limbs movements. In order to design the kinematics, dynamics and the mechani

5. Avaliação clínica e cinemática dos ajustes posturais compensatórios / Clinical and kinematics evaluation of compensatory postural adjustment
Postural control aims postural orientation and equilibrium in order an individual accomplishes a task in a stable way. Alterations of postural adjustment are related to musculoskeletal diseases and falls, supporting the importance of a complete posture evaluation in clinical practice, including static and dynamic components of posture. The aim of this study

6. Características cinemáticas do andar para trás em indivíduos com hemiparesia / Kinematics characteristics of backward walking in adult individual with hemiparesis
The backward walking (BW) has been used in protocols for rehabilitation and training in individuals with stroke, however little is known about their characteristics in terms of kinematic variables and motor pattern. The literature describes that for the execution of BW it is necessary to combine hip extension with knee flexion, components that are compromise

7. 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

8. Modelagem do robothron um manipulador de barras paralelas
The work approaches the modeling of the articulated robotic manipulator with six degrees of freedom, conceived for educational ends. Its presented the structure, the robotic anatomy and components, as systems of transmission, actuators and sensors used in manipulating robots. The arm and base structure of the Robothron manipulator are described. The forward

9. Geometry and kinematics of experimental antiformal stacks
Sandbox experiments with different boundary conditions demonstrate that antiformal stacks result from a forward-breaking thrust sequence. An obstacle blocks forward thrust propagation and transfers the deformation back to the hinterland in a previously formed true duplex. In the hinterland, continued shortening causes faults to merge toward the tectonic tran

10. Postural Feedback Scaling Deficits in Parkinson's Disease
Many differences in postural responses have been associated with age and Parkinson's disease (PD), but until now there has been no quantitative model to explain these differences. We developed a feedback control model of body dynamics that could reproduce the postural responses of young subjects, elderly subjects, and subjects with PD, and we investigated wh

11. Training affects the development of postural adjustments in sitting infants.
1. The present study addressed the question of whether daily balance training can affect the development of postural adjustments in sitting infants. 2. Postural responses during sitting on a moveable platform were assessed in twenty healthy infants at 5-6, 7-8 and 9-10 months of age. Multiple surface EMGs and kinematics were recorded while the infants were e

12. Ontogeny of postural adjustments during sitting in infancy: variation, selection and modulation.
1. The aim of the study was to find out whether the development of postural adjustments occurs via a coupling of simple muscle responses, such as stretch reflexes, or via selection from an innate repertoire of centrally generated response patterns. 2. Postural responses during sitting on a moveable platform were assessed in eleven healthy infants at 5-6, 7-8
