This dissertation intends to create a simulation of search and rescue (SaR) missions using Gazebo virtual world and Robot Operating System (ROS). The simulator is evaluated with multiple robots search using the Robotic Darwinian Particle Swarm Optimization (RDPSO) exploration algorithm, considering several real-world phenomena, such as radio frequency (RF) and voice. Although the RDPSO algorithm has already been developed and evaluated in Matlab environment, it cannot be directly implemented in real platforms. To address this disadvantage, ROS was chosen to implement the algorithm and, due to its compatibility with ROS, Gazebo was chosen as the simulation platform to evaluate multi-robot systems in SaR scenarios. For the RDPSO to be fully implemented, the RF signal and voice propagation models were equally implemented in ROS. For that matter, mathematic models, previously proposed in the literature, are analyzed and a study about the environment noise influence in missions of SaR based on voice localization is conducted. The RF model was simulated using the multi-wall method, which does not only consider the free space signal loss but also the loss of walls with different properties (e.g., thickness and type). The voice model is based on the RF model by adjusting the parameters to better adapt to the voice properties. The RDPSO algorithm, implemented in ROS, uses the RF model to simulate its mobile ad hoc network (MANET) connectivity component. In the context of finding victims, the RDPSO uses the voice propagation model to simulate the call for help by the victims. Environment noise was introduced in the simulation, which influenced the victims’ rescue rate by making harder for the rescue team to listen to the victim’s call. This influence is bigger as the environment noise level gets higher, thus there is the need for a better exploration of the map as the rescue team has to walk closer and closer to the victims, so that voice and noise can be distinguished.

Simultaneous Localization and Mapping (SLAM) is one of the most widely researched topics in Robotics. It addresses building and maintaining maps within unknown environments, while the robot keeps the information about its location. It is a basic requirement for autonomous mobile robotic navigation in many scenarios, including military applications, search and rescue, environmental monitoring, etc. Although SLAM techniques have evolved considerably in the last years, there are many situations which are not easily handled, such as the case of smoky environments where commonly used range sensors for SLAM, like Laser Range Finders (LRF) and cameras, are highly disturbed by noise induced in the measurement process by particles of smoke. There is an evident lack of solutions to this issue in the literature. This work focuses on SLAM techniques for reduced visibility scenarios. The main objective of this work is to develop and validate a SLAM technique for those scenarios, using dissimilar range sensors and by evaluating their behavior in such conditions. To that end, a study of several laser-based 2D SLAM techniques available in Robot Operating System (ROS) is firstly conducted. All the tested approaches are evaluated and compared in 2D simulations as well as real world experiments using a mobile robot. Such analysis is fundamental to decide which technique to adopt according to the final application of the work. The developed technique uses the complementary characteristics between a LRF and an array of sonars in order to successfully map the aforementioned environments. In order to validate the developed technique , several experimental tests were conducted using a real scenario. It was verified that this approach is adequate to decrease the impact of smoke particles in the mapping task. However, due to hardware limitations, the resulting map is comprehensibly not outstanding, but much better than using a single range sensor modality. This work is part of the Cooperation between Human and rObotic teams in catastroPhic INcidents (CHOPIN) R&D project, which intends to develop a support system for small scale SaR missions in urban catastrophic scenarios by exploiting the human-robot symbiosis.

This book examines the bottom-up applicability of swarm intelligence to solving multiple problems, such as curve fitting, image segmentation, and swarm robotics. It compares the capabilities of some of the better-known bio-inspired optimization approaches, especially Particle Swarm Optimization (PSO), Darwinian Particle Swarm Optimization (DPSO) and the recently proposed Fractional Order Darwinian Particle Swarm Optimization (FODPSO), and comprehensively discusses their advantages and disadvantages. Further, it demonstrates the superiority and key advantages of using the FODPSO algorithm, such as its ability to provide an improved convergence towards a solution, while avoiding sub-optimality. This book offers a valuable resource for researchers in the fields of robotics, sports science, pattern recognition and machine learning, as well as for students of electrical engineering and computer science.
