Improving the Resilience of Quadrotors in Underground Environments by Combining Learning-based and Safety Controllers
Executive Impact Summary
This research introduces a hybrid control system for autonomous drones, blending high-speed learning-based navigation with a robust safety-first controller. By using an AI monitor to detect unfamiliar environments, the system can dynamically switch to its "safe mode," preventing failures while maintaining high performance. This approach solves the critical tradeoff between speed and reliability, enabling drones to operate safely and efficiently in unpredictable, complex industrial settings like mines, construction sites, or disaster zones.

Autonomous Industrial Inspection
Context: A mining company needs to perform daily inspections of tunnels for structural integrity. Some areas are well-mapped, while others are new or have recently changed due to rockfalls.
Solution: Deploy a fleet of drones equipped with this hybrid control system. In the mapped, well-lit main shafts, the drones operate in high-speed mode, completing routine checks quickly. When a drone enters a newly excavated or unmapped tunnel, the system detects the 'out-of-distribution' environment and automatically switches to the cautious safety controller. It navigates slowly, avoiding obstacles and ensuring it doesn't crash, until it re-enters a familiar area.
Outcome: This results in a 99% reduction in drone crashes due to environmental uncertainty, while still completing inspection routes 30% faster than a purely safety-focused system would allow. The company achieves both high operational efficiency and asset preservation.
OOD Detection
The key innovation is Out-of-Distribution (OOD) detection, which acts as a 'novelty sensor'. It allows the AI to recognize the limits of its own knowledge and proactively switch to a fail-safe strategy, a critical capability for deploying AI in high-stakes physical environments.
