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

2. Global optimal path planning of an autonomous vehicle for overtaking a moving obstacle
In this paper, the global optimal path planning of an autonomous vehicle for overtaking a moving obstacle is proposed. In this study, the autonomous vehicle overtakes a moving vehicle by performing a double lane-change maneuver after detecting it in a proper distance ahead. The optimal path of vehicle for performing the lane-change maneuver is generated by a

4. Image matching and classification for UAV navigation.
Unmanned aerial vehicles, known as UAVs, have evolved over the past two decades to sophisticated aircraft robots able to carry out surveillance, recognition, remote sensing and even attack missions. But there are not many alternatives of autonomous navigation systems for most of these aircraft which still require human intervention to navigate. Devices such

5. 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

7. 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

8. Active system of auto-stabilization for suspended vehicles. / Sistema ativo de auto-estabilização para veículos suspensos.
During the last decades, many researches and studies have been done about suspended vehicles such as chair lifts, cable cars, carrying and assemblies of parts in the industry, etc. Suspended vehicles behave like a pendulum and they are susceptible to the action of external forces which cause oscillations and unwanted swing at the vehicle that may affect func

9. Estimação não parametrica da trajetoria percorrrida por um veiculo autonomo / Non-parametric curve estimation of an autonomous vehicle trajectory
The objective of this study is to find a smooth function joining two points A and B with minimum length constrained to avoid fixed subsets. A penalized nonparametric method of finding the best path is proposed. The method is generalized to the situation where stochastic measurement errors are present. In this case, the proposed estimator is consistent, in th

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

12. 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
