Simulated Sensors in Gazebo

Why This Matters

Simulated sensors are useful because they let teams test graph behavior before hardware is ready or available. They become misleading when their idealized behavior is mistaken for real sensor behavior.

Distilled Takeaways

• Simulated sensors are best used to test system integration and behavior logic.
• Their fidelity should be matched to the question being asked.
• Noise, latency, field of view, and frame semantics still matter.
• A passing simulation result is evidence, not proof, of hardware readiness.

Practical Guidance

• Decide whether the test needs structural realism or high physical realism.
• Validate topic names, frames, and timestamps as carefully as real sensors.
• Add realistic imperfections when they matter to the behavior under test.
• Compare simulated and hardware behavior before trusting simulator-based conclusions.
