Researchers have developed a new cooperative indoor guidance framework for unmanned aerial vehicles (UAVs) that utilizes a shared voxel-map world model combined with a multi-agent Soft Actor-Critic (MASAC) controller. This system allows multiple drones to fuse LiDAR observations into a common occupancy map, which is then processed into a bird's-eye-view representation for decentralized control. The MASAC controller integrates map features, obstacle data, and goal information, achieving a 90.3% success rate in simulated corridor navigation, surpassing traditional planning and control methods. Further adaptation with offline imitation fine-tuning from real-world data enabled stable cooperative operation in GNSS-denied indoor environments. AI
