13. 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

14. Uma arquitetura de controle para um robô quadrúpede com comportamento reflexivo de estabilidade
This thesis presents a control architecture for a quadruped Robot with 16 degrees of freedom (4 per leg), the Guará*. The proposal to develop this architecture aims to set a problem study platform inherent to mobile four-legged robots, such as the walking generation, the complex movement control, the obstacle transposition, and the stability reflex implemen

16. TIP OVER AND SLIPPAGE CONTROL OF MOBILE ROBOTIC SYSTEMS OVER ROUGH TERRAIN / CONTROLE DE CAPOTAGEM E DESLIZAMENTO DE SISTEMAS ROBÓTICOS MÓVEIS EM TERRENOS ACIDENTADOS
The use of mobile robots to monitor non-accessible environments has become increasingly common in the recent years. These tasks can be either autonomous, remote-controlled, or passenger-operated. When performed in rough terrain, it is necessary to guarantee mission safety, since many times it is impossible to send a rescue party for recovery. The hybrid envi

19. Contribuição ao planejamento de trajetória de robôs através de elementos de dinâmica, controle e otimização / Contribution to robot path planning through dynamics, control and optimization
Robotic manipulators are programmable devices designed to execute a great variety of tasks in a repetitive way. In industrial environments, the reduction of dynamic requirements associated to a specific task can result in productivity increase and cost reduction regarding the robotic operation and maintenance. Moreover, the reduction of such requirements can

21. Controle dinâmico de robôs móveis com acionamento diferencial
This work addresses the dynamic control problem of two-wheeled differentially driven non-holonomic mobile robot. Strategies for robot positioning control and robot orientating control are presented. Such strategies just require information about the robot conguration (x, y and teta), which can be collected by an absolute positioning system. The strategies de

22. Model predictive disturbance rejection during cooperative mobile robot assembly tasks
This paper addresses the problem of disturbance compensation for the successful assembly of structures by mobile field robots. A control architecture, consisting of a linear PID joint controller with model predictive feed-forward compensation for mobile base motions and interactive-force disturbance rejection is discussed. Object insertion is achieved by pre

23. Uma abordagem comportamental para inserção de robôs em ambientes culturais
In this work, we propose methodologies and computer tools to insert robots in cultural environments. The basic idea is to have a robot in a real context (a cultural space) that can represent an user connected to the system through Internet (visitor avatar in the real space) and that the robot also have its representation in a Mixed Reality space (robot avata

24. Navegação e controle de robôs móveis cooperativos: uma abordagem baseada em conectividade de grafos
This thesis addresses the problem of motion planning and control of groups of autonomous mobile robots during cooperative tasks execution. A general framework that transforms several cooperative tasks into the same basic problem is developed thus providing a feasible solution for all of them. The approach enables using a single team of robots to perform nume
