Multi-Floor Mapping Strategies

Source: ros2-copilot-skills multi-floor mapping skill

Why This Matters

Multi-floor environments add a conceptual layer to mapping: floor identity becomes part of navigation state. Treating the whole building as one naive 2D map usually creates more ambiguity than value.

Distilled Takeaways

• Separate-floor maps are often easier to deploy and maintain than one forced global artifact.
• Floor selection becomes an autonomy and localization concern, not just a map-storage detail.
• Elevators, stairs, and transitions need explicit system logic around them.
• Multi-floor systems work best when map management and mission sequencing are kept clear.

Practical Guidance

• Treat floor changes as explicit state transitions in the robot mission.
• Keep per-floor maps versioned independently.
• Define how the robot knows which floor map is active.
• Avoid overcomplicating global map structure when a simpler per-floor model is operationally clearer.
