AWARE is a bio-inspired active sensing framework designed for human-in-the-loop UAV operation in challenging real-world environments. By combining whole-body active yawing with hybrid adaptive RL-MPC control, it expands LiDAR perception, improves localization robustness, and supports safe real-time flight.

Research Overview

Abstract

Human-in-the-loop (HITL) UAV operation in complex and safety-critical environments demands reliable onboard localization, yet lightweight platforms equipped with narrow-field-of-view LiDAR often suffer from limited sensing coverage. As a result, LiDAR-inertial odometry can become fragile in geometrically degenerate and feature-sparse scenes.

AWARE addresses this challenge with a bio-inspired whole-body active yawing strategy that expands the effective sensing horizon without additional actuation. The framework couples differentiable Model Predictive Control (MPC) with Reinforcement Learning (RL): MPC selects observability-aware yaw actions, RL adapts control weights online to balance information gain and flight stability, and a Safe Flight Corridor preserves operator intent for safe human-autonomy cooperation. Across both simulated and real-world experiments, AWARE consistently surpasses passive scanning and static optimization baselines while maintaining real-time performance on resource-constrained UAV hardware. These properties make AWARE particularly valuable for UAV-based surveying and mapping, where robust localization is essential for reliable geospatial data acquisition in complex field environments.

Key Features & Contributions

Bio-inspired Active Yawing

Inspired by biological active sensing, AWARE uses whole-body yaw rotation to expand the effective LiDAR sensing horizon and improve perception quality without extra mechanical actuation.

Hybrid RL + MPC

A differentiable MPC searches observability-aware yaw actions, while a lightweight RL policy adapts control weights online to balance information gain and flight stability.

Human-autonomy Cooperation

A Safe Flight Corridor preserves operator navigation intent while decoupling autonomous yaw optimization, enabling safe and effective human-in-the-loop interaction.

Real-time Performance

Extensive simulation and real-world experiments show robust localization gains over passive scanning baselines while maintaining onboard real-time performance.

Real-world Experiments

AWARE is designed for challenging real-world and human-in-the-loop UAV scenarios where sensing coverage, localization robustness, and safe cooperative control must all be maintained.
