Enabling Autonomous Search and Rescue in Dynamic Environments
Robots can revolutionize Search and Rescue (SaR) by autonomously undertaking dangerous tasks. This paper proposes an integrated control framework for SaR robots to safely navigate dynamic, cluttered environments with uncertainties, effectively avoiding static and moving obstacles.

Unified Planning & Control Framework
Our framework integrates a greedy heuristic path planning system with a robust Tube-based Model Predictive Control (TMPC) system into a single-layer architecture. This design synergizes the responsiveness of heuristic reasoning with the constraint-handling guarantees of MPC-based systems, leading to enhanced computational efficiency and safety compared to traditional bi-level planning-control schemes.
Dynamic Obstacle Avoidance via Obstacle Belts
We extend the path planning system to handle moving obstacles by predicting their trajectories and aggregating them into time-indexed constraint regions, called obstacle belts. This enables anticipatory collision avoidance, a critical feature for safe navigation in rapidly changing disaster environments.
Uncertainty-Aware TMPC Reformulation
The TMPC system is reformulated by replacing its nominal controller with the heuristic planning mechanism, while retaining the ancillary controller for robust trajectory tracking. This approach incorporates time-varying constraints and dynamic tightening to account for both external disturbances and perception uncertainty, ensuring consistent safety margins.
Stateless, Perception-Driven Control
Our framework operates without memory of past states, relying solely on real-time perception. This non-restrictive design reduces reliance on heavy infrastructure and enables deployment in partially observable environments typical of SaR missions, making it highly adaptable and efficient for autonomous robot operation.

Real-world Scenario Resilience for SaR Robotics
The simulations robustly demonstrate HP+TMPC's superior performance in dynamic, cluttered environments, outperforming state-of-the-art methods by effectively handling moving obstacles and bounded uncertainties. This architecture maintains safety and achieves mission objectives, even in high-risk scenarios (e.g., navigating between two converging dynamic obstacles), showcasing its strong potential for real-world deployment in critical Search and Rescue operations. Its 'stateless' nature and computational efficiency are particularly advantageous for post-disaster scenarios with limited sensing and computational resources, reducing reliance on extensive historical data or complex infrastructure.
