1. Estudo de coordenação de robôs móveis com obstáculos / Study of coordination of mobile robots with obstacle avoidance
Coordenação de robôs móveis é um tópico importante de pesquisa dado que existem tarefas que podem ser desenvolvidas de forma mais eficiente e com menor custo por um grupo de robôs do que por um só robô. Nesta dissertação é apresentado um estudo sobre coordenação de robôs móveis para o problema de navegação em ambientes externos. Para isso,

2. Methodology to detect obstacles for autonomous navigation of vessels using computer vision / Metodologia para detecção de obstáculos para navegação de embarcações autônomas usando visão computacional
Este trabalho apresenta um novo método de detecção de obstáculos usados para navegação de um barco autônomo. O método desenvolvido é baseado em visão computacional e permite medir a distância e direção do obstáculo à câmera de video. A distância do possível obstáculo à câmera de vídeo, e o vetor de contorno predominante da imagem são o

11. DETERMINANTS AND STRATEGIES FOR THE ALTERNATE FOOT PLACEMENT
Undesirable landing area (e.g., a hole, a fragment of glass, a water puddle, etc) creates the necessity for an alternate foot placement planning and execution. Previous study has proposed that three determinants are used by the central nervous system (CNS) for planning an alternate foot placement: minimum foot displacement, stability and maintenance of forwa

12. 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
