Ask HN: Is AI-based debugging for robotics feasible?

[Lazaruscv]

* Can AI models meaningfully detect “emergent” errors (timing drift, sensor desync, hardware degradation)?

* Or is this a problem better solved through deterministic verification and better tooling?

Would love to hear real-world perspectives from those working in robotics infrastructure, fleet management, or simulation , what’s actually working (or not)?

You seem to describe the problem of automated anomaly detection. Many companies tried or are trying to solve this (e.g., Heex), but I don't think anyone has done it definitively. The issue is that "normal" behavior keeps changing, so its difficult to build a model of what is abnormal. And by the time the behavior of the robots in the fleet becomes more stable (in all aspects, physical, electrical, networking, logging, etc.), it's usually easy for the engineers who built it to put in the right metrics and health-monitoring checks to detect issues. So even though theoretically automated anomaly detection sounds like the holy grail of fleet observability, in practice, it's not such a big deal.

So I guess to answer your question, I think yes, the second, better tooling (and a ton of metrics data collected from the fleet with good versioning).

Basic arithmetic can meaningfully detect every error you just listed. AI probably cannot "beat the odds" against a simple integral function.

True, for isolated signals, absolutely. But in real-world robotics systems, the challenge isn’t doing the math, it’s seeing the context.

Timing drift or sensor desync rarely appear as clean numerical mismatches, they emerge across hundreds of async topics, network delays, or subtle hardware degradations. Arithmetic can flag the symptom, but not always the cause or pattern that leads to it.

The idea behind AI here isn’t to replace deterministic checks, it’s to augment them. Think of it as spotting correlations or early warning trends that static rules can’t (like cross-sensor covariance shifts before failure).

Arithmetic finds the what; AI helps predict the why and when.

Yes they can but they need grounding to mitigate infinite regress and hallucination. They can be grounded as a y combinator fixed point λ := ∀x (x -> x).
