AUTONIX: Autonomous Acoustic Fire Suppression & Deep-Rubble Rescue Rover

Edge Processing Architecture: Powered by a dual-core ESP32 microcontroller operating on a custom FreeRTOS task architecture, isolating the real-time sensor polling loop (Core 1) from the high-frequency Wi-Fi/WebSocket uplink (Core 0) to guarantee zero watchdog timeouts. .Non-Destructive Suppression Payload: Integrates a high-power acoustic driver driven by an IRLZ44N logic-level MOSFET. The ESP32 utilizes its hardware LEDC PWM API to push precise 40–60 Hz square waves at a 50% duty cycle, displacing air mass through an airtight resonance enclosure to starve flames of oxygen. .Sensor Fusion & Hardware Telemetry: * Life Detection: Integrates a military-grade mmWave radar operating via non-blocking UART to parse human vital signs (respiration/heartbeats) through solid barriers. .Navigation: Employs an HC-SR04 ultrasonic array for automated collision avoidance (halting at a strict <30cm threshold) and a 5-channel directional flame sensor array to dynamically compute flame approach vectors. .Dual-Mode Failsafe Communication: Streams live JSON telemetry (<5ms latency) and ESP32-CAM MJPEG HTTP video to a custom Mission Control dashboard over high-speed WebSockets. It features an integrated Web Serial API fallback, allowing first responders to pull direct physical USB telemetry if local Wi-Fi infrastructure completely collapses. .Strict Power Isolation: Engineered with dedicated power rails to prevent brownouts. The 12V high-current acoustic payload and L298N motor drivers are galvanically isolated from the sensitive 3.3V/5V microcontroller logic lines, united exclusively by a shared common ground bridge.
