About

David Portugal is a robotics researcher whose work spans autonomous systems, multi-robot coordination, simultaneous localization and mapping (SLAM), and human-robot interaction. He has made particularly significant contributions to the field of multi-robot patrolling, authoring an influential survey on cooperative patrolling algorithms (115 citations) and developing foundational approaches including the MSP algorithm and scalable, fault-tolerant distributed patrol frameworks that together have shaped how researchers design coordinated robotic teams. His rigorous comparative evaluations of 2D SLAM techniques within the Robot Operating System (ROS) environment — now cited over 250 times — have become an essential reference for practitioners selecting navigation solutions. Portugal has also advanced distributed robotics by exploring computation sharing for SLAM across robotic clusters, demonstrating a keen interest in making sophisticated algorithms practical on resource-constrained platforms. His work extends beyond theoretical robotics into meaningful real-world applications, including the deployment of service robots in elderly care settings (132 citations) and multi-robot systems for wildfire prevention through the SEMFIRE project. Complementing his research, he has contributed to robotics education by integrating Arduino-based mobile robots into ROS curricula. With a broad, impactful body of work accumulating nearly 1,000 citations, Portugal represents a versatile and practically minded voice in modern robotics research.
