Wait Behavior in Nav2

Source: ros2-copilot-skills wait behavior skill

Why This Matters

Sometimes the correct action is to do nothing briefly. A wait behavior can be a genuine autonomy tool when it gives a dynamic obstacle time to clear, sequences a task safely, or prevents the robot from escalating too quickly into more aggressive recovery actions.

Distilled Takeaways

• Wait is useful when time itself changes the situation, not when the system is just confused.
• It can reduce unnecessary motion in crowded or human-shared environments.
• Wait belongs in recovery and autonomy sequences when there is a clear temporal reason for it.
• Overuse of wait can hide deeper issues in planning, sensing, or sequencing.

Practical Guidance

• Use wait for dynamic-obstacle patience, interaction timing, or controlled task sequencing.
• Keep durations tied to a reason, not to habit.
• Evaluate whether wait actually improves mission success or just delays failure.
• Combine wait with clear follow-up actions so the tree resumes with intent.
