rosbag2 Analysis Workflows

Why This Matters

Recorded data is one of the best ways to make robot failures inspectable after the fact. rosbag2 becomes much more valuable when it is used deliberately for comparison, replay, and diagnosis rather than opportunistic logging.

Distilled Takeaways

• Bag analysis turns one robot run into a repeatable debugging artifact.
• The right bag content depends on the question being investigated.
• Analysis is strongest when recording discipline and metadata are already in place.
• Replay-friendly data collection reduces the cost of investigating intermittent failures.

Practical Guidance

• Record bags with a known debugging purpose whenever possible.
• Keep notes about scenario, robot state, and configuration alongside important bags.
• Compare multiple runs to isolate regressions and environmental effects.
• Use bags to validate fixes, not only to explain failures.
