Distributed Intelligence for Multi-Agent Systems in Search and Rescue
Unfavorable environmental and (or) human displacement may engender the need for Search and Rescue (SAR). Challenges such as inaccessibility, large search areas, and heavy reliance on available responder count, limited equipment and training makes SAR a challenging problem. Additionally, SAR …

Autonomous Search and Rescue: Real-Time Drone and Robotic Dog Integration
… such as indoor facilities, underground passages, and disaster zones, where GPS is not available. This research explores the integration of a Boston Dynamics Spot robot with a Tello drone to form a non-GPS-based autonomous navigation system. By leveraging coordinate transformation logic, this study …

Reliable and resource-aware collaborative SLAM for multi-robot search and rescue
Collaborative simultaneous localization and mapping (CSLAM) is a core capability for many multi-robot systems operating in GPS-denied environments. Motivated by the application of forest search and rescue, this thesis presents two contributions that advance state-of-the-art CSLAM systems. The first …

Reinforcement Learning with a Lost Person Model for Search and Rescue Path Planning
… a reinforcement learning agent to plan paths for search and rescue applications using a model of lost person behavior trained on past search incidents. We propose an improved method for producing occupancy maps from the trajectories of an agent-based lost person model. We demonstrate that through …

A Stackelberg signaling game for co-operative rendezvous in uncertain environments in a search-and-rescue context
Search and rescue (SAR) operations are challenging in the absence of a medium of communication between the rescuers and the rescuee. Natural signaling, grounded in rationality, can play a decisive role in achieving rapid and effective mitigation in such rescue scenarios. In this work, we model a …
