1. Relative Motion Guidance, Navigation and Control for Autonomous Orbital Rendezvous
ABSTRACT: In this paper, the dynamics of the relative motion problem in a perturbed orbital environment are exploited based on Gauss' variational equations. The relative coordinate frame (Hill frame) is studied to describe the relative motion. A linear high fidelity model is developed to describe the relative motion. This model takes into account primary gra

3. Uma proposta de controle neural adaptativo para a navegação de veículos autônomos / Autonomous vehicle navigation control: an adaptative neural networks proposal
Os equipamentos robóticos foram inicialmente criados para atuarem em ambientes industriais fechados. Com o passar do tempo, melhorias foram conquistadas. Atualmente, não se limitam mais à realização de tarefas simples e repetitivas em locais especialmente preparados. Novos equipamentos, capazes de atuarem em ambientes abertos e de realizarem as mais div

4. Fuzzy logic based navigation system for an autonomous / Sistema de navegação para veículo autônomo utilizando lógica difusa
This work had as a goal the development of a fuzzy logic based navigation control system for an autonomous vehicle. The developed control system was named SNAT (from the equivalent in portuguese of autonomous navigation system for a tricycle). The system controls and monitors the navigation of the vehicle from a remote base station using a telemetry data lin

5. Use of Kalman filter and computational vision for the correction of uncertainties in the navigation of autonomous robots / Uso de filtro de Kalman e visão computacional para a correção de incertezas de navegação de robos autonomos
The work establishes a collection of procedures for image based navigation control of an autonomous robot. Intensity maps obtained from cameras are transformed in depth maps, which provide information about the robot s localization in an environment, comprised of distinct objects. A two wheeled, differential powered robot model is used, allowing the navigati

6. 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

7. Geração de trajetórias para veículos aéreos autônomos não-tripulados
In this work a study on the problem of the trajectory generation for unmanned aerial vehicles is carried through. The main objective is to provide tools of path planning for aerial robots, taking into account some of its main physical constraints of movement. For this, some of the more used techniques for motion planning of grounded robots are argued initial

10. Estudo sobre robos de locomoção : formas construtivas, dirigibilidade e controle
The objective of this work is to study the constructive forms more viable to build an autonomous vehicle for people with some physical deficiency. This vehicle will be called as mobile robot, because the vehicle s results can be applied to this type of robots. Initially an introduction to main driven forms applied to mobile robots and the study of tires moti

12. Aplicação de metodos de computação flexivel em navegação autonoma de veiculos
Autonomous vehicle navigation is a well-known and typical example of an autonomous control problem. This type of control problem involves a very complex, unstructured environment. The great amount of parameters preclude the use of a mathematical model of the environment. Thus, autonomous control demands constantly adapting, locally situated control methods,
