ScanDreamer: A Map-Grounded World Model for Quadrotor Navigation

ScanDreamer: A Map-Grounded World Model for Quadrotor Navigation

Summary

This paper introduces ScanDreamer, a world model designed for quadrotor navigation in cluttered, unknown environments.

Editorial context

The study presents ScanDreamer, a map-grounded world model for quadrotor navigation that combines explicit geometric memory with perception-aware motion constraints to achieve 96.3% success and 3.6% collision rates in unseen environments within NVIDIA Isaac Sim.

arXiv:2611.11605v1 Announce Type: new Abstract: Quadrotors inspecting buildings and tunnels must navigate unknown clutter with a forward-facing depth camera whose limited field of view constrains scene understanding and collision-avoiding navigation. Recent world-model agents learn navigation through imagined experience (e.g., AirDreamer), but remain data-intensive and often lack explicit geometric memory and awarene

\pm$ 3.0% success and 28.8 $\pm$ 2.8% collision for AirDreamer at the same online-interaction budget. Removing the forward-cone penalty increases collisions to 9.9 $\pm$ 3.1%. These results show that combining explicit map memory, map-grounded imagination, and perception-aware motion substantially improves navigation performance and data efficiency.
