ADLER

The browser reads the operator's controller input and passes it to the laptop ground server, which turns it into control intent for the drone. That intent travels over Wi-Fi to the Raspberry Pi bridge and then reaches the flight controller over UART using the MultiWii Serial Protocol.

At the click of a button, the operator can switch ADLER into a fully autonomous mode that pursues predefined goals.

Telemetry follows the same path in reverse, allowing the dashboard to show the drone's state and the health of each connection.

ADLER keeps its final safety boundaries close to the drone. The onboard bridge validates incoming commands, clamps channel values, monitors connection freshness, and stops forwarding stale control intent.

INAV remains the final flight-controller failsafe authority, and every stage is designed to fail predictably when a control connection is lost.
