5 Quick Tips for ROS2 Navigation

I’ve been working extensively with ROS2 Navigation and wanted to share some quick tips that saved me headaches:

1. Always check your TF tree — most navigation failures are TF issues.
2. Use rclpy.time.Time().to_msg() wisely for timestamp consistency.
3. Depth and laser fusion makes marker navigation far more stable.
4. Watch for transform extrapolation errors — they silently break navigation.
5. Keep your marker detection lightweight if using compressed images.

I’ll share more detailed posts soon. Hope this helps someone!
