Robodor RCS

Robodor makes the drives that door manufacturers build into industrial doors. RCS lets a manufacturer see every door they have installed, across all their sites. A small ESP32 module plugs into each drive: a technician's phone sets the door up nearby over Bluetooth, and the door then reports to a server, where state, faults and settings appear in a web panel or a mobile app. It succeeds the company's earlier connected-door prototypes.

One Rust protocol core decodes the drive for every product — the server links it directly, iOS through a C FFI and Android through JNI — because two decoders can silently disagree about a fault. Nothing is hard-coded: the register map is read from the drive itself. Modules hold a mutual-TLS link to a Rust (axum) server on Postgres, report slowly by default and every 500 ms only while someone is watching a door. A thousand-door simulation took the server from dropping readings to storing all of them at 0.11 CPU cores and 153 MB, and a single-door view went from 18 MB to 3 KB per request. The managed AWS setup cost about $63 a month with zero doors; it now runs on one small machine. Safety is enforced server-side: mass remote actuation is refused for every account, and every remote write is logged before it is sent.
