Hi PX4 Community,
Couple weeks ago, we launched an open source tool called Bagel. It allows you to troubleshoot PX4 ULogs using natural language, just like how you use ChatGPT.
We released a new feature today to address a common concern raised by the community.
“We don’t trust LLM math.”![]()
That’s feedback we kept hearing from the PX4 community regarding Bagel.![]()
We heard you, so we built a solution: whenever Bagel needs to do a mathematical calculation on a robotics log, it now creates a DuckDB table and runs a clear SQL query against the data.
That makes Bagel’s math:
• Transparent – you see the query and verify it manually.
• Deterministic – no “LLM guesswork.”

We’re launching this today and would love community feedback
