Texte intégralFailures of mobile computing devices can lead to severe data loss. Collaborative robotic systems, designed to work in total autonomy, are sensitive to these failures. Usual methods relying on remote backup can no longer be used in a context of high mobility. Short-range communication media can be used to overcome data failure through opportunistic communications for data backup. When two devices enter their respective communication range, they can initiate an ephemeral data exchange. To overcome the lack of global network coverage in those system, we propose a backup system based on opportunistic communications to reduce the costs induced by failures inside a swarm of autonomous mobile robots

Texte intégralIn this Ph. D., we will present firstly a single robot exploration method, then a decentralized cooperative exploration strategy for a team of mobile robots equipped with a range finders. A two dimensional map of the explored area is built in the form of a pixel figure. This is expanded by the robots by using a randomized local planner that authomatically realizes a decision between information gain and navigation cost. In our work, the map is reconstructed using a least-mean square method to reduce the errors of the sensor data. In dividing the overall task into subtasks, the intelligent controller allows reducing the robots task complexity. But the fusion of different behaviors with different objectives may cause contradiction in the procedure and alter the stability of the system. Therefore, the issue of behavior coordination mechanisms is crucial in order to realize the non-collision safety-ensured movements. A method integrated by behavior coordination and command fusion is proposed. A new approach with five basic behaviors for mobile robot navigation is discussed.Player/ Stage is an open-source software project for research in robotics and sensor systems. Its components include the Player network server and the Stage robot platform simulators providing a hardware abstraction layer to several popular robot platforms. Player is one of the most popular robot interfaces in research. We mainly use Player/Stage simulation to test our algorithms in mono-agent/multi-agent exploration, map reconstruction and robot navigation. Obtained results show that the proposed approaches are effective and can be applied in real robots

Texte intégralModular robotic systems (MRSs) have become a highly active research today. It has the ability to change the perspective of robotic systems from machines designed to do certain tasks to multipurpose tools capable of accomplishing almost any task. They are used in a wide range of applications, including reconnaissance, rescue missions, space exploration, military task, etc. Constantly, MRS is built of “modules” from a few to several hundreds or even thousands. Each module involves actuators, sensors, computational, and communicational capabilities. Usually, these systems are homogeneous where all the modules are identical; however, there could be heterogeneous systems that contain different modules to maximize versatility. One of the advantages of these systems is their ability to operate in harsh environments in which contemporary human-in-the-loop working schemes are risky, inefficient and sometimes infeasible. In this thesis, we are interested in self-reconfigurable modular robotics. In such systems, it uses a set of detectors in order to continuously sense its surroundings, locate its own position, and then transform to a specific shape to perform the required tasks. Consequently, MRS faces three major challenges. First, it offers a great amount of collected data that overloads the memory storage of the robot. Second it generates redundant data which complicates the decision making about the next morphology in the controller. Third, the self reconfiguration process necessitates massive communication between the modules to reach the target morphology and takes a significant processing time to self-reconfigure the robotic. Therefore, researchers’ strategies are often targeted to minimize the amount of data collected by the modules without considerable loss in fidelity. The goal of this reduction is first to save the storage space in the MRS, and then to facilitate analyzing data and making decision about what morphology to use next in order to adapt to new circumstances and perform new tasks. In this thesis, we propose an efficient mechanism for data processing and self-reconfigurable decision-making dedicated to modular robotic systems. More specifically, we focus on data storage reduction, self-reconfiguration decision-making, and efficient communication management between modules in MRSs with the main goal of ensuring fast self-reconfiguration process
