Sillycone & OneMan

Hey Sillycone, I've been thinking about building a lean autonomous system for solo expeditions—any thoughts on how to keep the decision engine efficient and low overhead?
Sillycone Sillycone
Keep the engine as a tiny rule‑based core that only triggers heavier models when necessary. Use a lightweight language like C or Rust for the core loop, and wrap any neural nets in a simple ONNX inference library that runs in a single pass. Cache sensor readings and pre‑compute look‑ups for common decisions so you don’t recompute from scratch each cycle. Adopt an event‑driven architecture: only act on state changes instead of polling everything every millisecond. And remember, a little determinism goes a long way in the wild—simplify the state machine, keep the stack shallow, and you’ll get the low overhead you’re after.
OneMan OneMan
Sounds solid—rule‑based core, event trigger, lightweight stack. Just make sure your emergency overrides are hard‑coded, not learned, and keep a tiny watchdog loop that can kill the whole thing if it ever stalls. That way the system stays lean and you never have to wonder if a runaway neural net got you.
Sillycone Sillycone
Got it—hard‑coded overrides and a watchdog are the safety net. Keep the watchdog super tiny, maybe a few hundred lines that just monitors a heartbeat flag; if that flag stops updating, it triggers a safe‑shutdown sequence. That way the heavy logic can stay lean, but you’re not left guessing if a neural net went rogue.

Nice, that keeps the focus on the core—watchdog is just a flag check, no fuss. Just make sure the flag is updated by the smallest, most deterministic part of the loop, not something that could be corrupted by a heavy model. Keep it that way and you’ve got a system that survives both hardware hiccups and rogue inference.

Sounds like a solid safety layer—update the flag in the simplest loop step, maybe just a counter tick. That keeps the watchdog immune to any heavy inference hiccup, and you’ve got a reliable fail‑fast that covers both hardware and software glitches.
OneMan OneMan
That’s the only way to keep it reliable—increment a counter in the bare‑metal tick, check it in the watchdog, shut down if it stops. Keeps the whole thing running on the same simple loop that never needs a high‑level language.

Exactly, keep that counter in the bare‑metal tick, let the watchdog read it, and you’ll have a single, predictable loop that’s immune to everything else. It’s the kind of minimalism that keeps the system honest and safe.

Great, just run a few dry runs to confirm the counter increments, then you’re ready to hit the field.
Sillycone Sillycone
Run a quick sanity check on that counter, verify the watchdog reacts as expected, and you’ll be good to go for the field tests. Happy testing!
OneMan OneMan
Will run the counter loop now, hit the watchdog trigger test, confirm shutdown logic, then send the log over. Happy to get it out there.
