Robotic Systems for Urban Search and Rescue Operations

Urban search and rescue (USAR) presents complex challenges in hazardous environments where human access is restricted or dangerous. Robotic systems have emerged as indispensable tools to extend the capabilities of emergency responders by providing reconnaissance, mapping, victim detection and communication support. Ground robots equipped with robust locomotion and advanced sensors can traverse debris-strewn terrain, while aerial platforms offer rapid surveys and relay critical data. Hybrid solutions draw inspiration from biological locomotion to achieve high manoeuvrability in confined spaces. At the core of USAR robotics are algorithms for simultaneous localisation and mapping, path planning and multi-robot coordination, enabling single platforms or heterogeneous fleets to collaboratively cover collapsed structures, identify survivors and maintain reliable communication links. Recent advances in autonomy, lightweight sensing, machine learning for image and sound recognition, and resilient communication networks have accelerated the deployment of robotic teams in real disaster scenarios. These systems are designed to interoperate with first responders, providing real-time situational awareness, reducing risk to personnel and expediting lifesaving interventions. The global significance of USAR robotics spans earthquake relief, urban flood response and industrial incidents, with active research driving enhancements in robustness, efficiency and cost-effectiveness.

Technical terms

Simultaneous Localisation and Mapping (SLAM): A process by which a robot builds a map of an unknown environment while estimating its own position within that map.

Multi-robot coordination: Strategies and algorithms that enable multiple robots to cooperate, share information and distribute tasks to achieve collective objectives.

Inertial Measurement Unit (IMU): A sensor suite combining accelerometers and gyroscopes to track a robot’s motion and orientation.

Active perception: A control strategy where robots adapt their sensing actions, such as adjusting camera viewpoints, to improve environmental understanding.

Occupancy grid: A spatial representation dividing the environment into cells that are marked as free, occupied or unknown, used for navigation and mapping.
