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

3. Implementation Analysis of a Washout Filter on a Robotic Flight Simulator - a Case Study
ABSTRACT This paper presents a detailed analysis about the implementation of a washout filter on the SIVOR (Simulador de Voo Robótico - Robotic Flight Simulator) project. The main objective of this project is to develop, on an anthropomorphic robot, a flight simulator which can be used as an Engineering Development System (EDS) and a pilot training platform

4. Tracking control of a planar five-link bipedal walking system with point contact, considering self-impact joint constraint by adaptive neural network method
AbstractIn order to achieve the practical characteristics of natural bipedal walking, a key feature is to realize "the straight knee state of walking" during stance and swing motions. Considering a straight knee necessitates that the shank link of each leg not to undergo the rotation angles which are greater than that of the thigh link. For this purpose, var

5. ARQUITECTURA HARDWARE-SOFTWARE PARA DISEÑO, ANÁLISIS Y CONTROL DE ROBOTS
This work presents a design and control methodology in real time using low cost hardware, working on a real robot as well as on a simulation, in a coordinated way. The methodology starts in the design phase using a CAD tool and generates the model of the robot in Matlab and Simulink as integration platforms, which are widely used tools in design and control

6. In-flight collision avoidance controller based only on OS4 embedded sensors
The major goal of this research was the development and implementation of a control system able to avoid collisions during the flight for a mini-quadrotor helicopter, based only on its embedded sensors without changing the environment. However, it is important to highlight that the design aspects must be seriously considered in order to overcome hardware lim

7. Design of CAN-based distributed control systems with optimized configuration
A current trend in distributed control systems is the application of communication networktechnologies such as CAN - Controller Area Network. A recent utilization approach ofthese technologies is the networked control systems (NCS). The fundamental challenges inthe development of NCS are the analysis of the network delay effects and the prediction of the tim

8. 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

9. Dispositivo automático para auxiliar a manipulação de cargas. / Automatic device to assist the handling materials.
The material handling is one task in which robot is commonly employed to replace the human work because it has some advantages such as, higher precision in the handling and higher speed of the task, and to increase operator safety. Despite these advantages, the robotic device is most employed only in situation that speed and precision are essential; in other

10. Design of biped robots with simple dynamics: modeling, control and trajectory generation. / Projeto de robôs bípedes com dinâmica simplificada: modelagem, controle e síntese de trajetórias.
In this thesis we present a new class of biped robots with articulate legs and a torso. The proposed design is constructed by means of applying counter- balances to each link of the leg, and therefore it has some properties that simplifies dramatically the dynamics of the robot. We prove that the result- ing system, under certain assumptions, is exact linear

11. Synthesis of autonomous controllers in mobile robotics through bio-inspired computing / Sintese de controladores autonomos em robotica movel por meio de computação bio-inspirada
Novel techniques for autonomous robot navigation aim at fulfilling the growing demand for mobile robots in multiple segments of society and in a plethora of tasks. The challenges involved in developing the system which controls the robot allow to say that the intelligence embedded in the current robots is found to be still incipient and limited. In this work
