Keeping humans safe around robots with Rust
summary
Sonair builds an functional safety-certified ADAR sensor concept using Rust on a multicore Cortex‑A platform, moving from Raspberry Pi prototypes to bare‑metal quad‑core A53 compute with an M4 integrity core. The system handles >64 configurable safety zones, meets a 100 ms stop‑decision window by starting processing as samples arrive, uses an atomic counter multi‑core scheduler, and even benchmarks an AI‑generated FFT faster than vendor DSP. ADAR 1.0 ships functionally, evaluation is ongoing, safety certification targets Q1.
