Flare is a compact drone demonstrator developed within the SAMURAI project (Safe Multicopter for Reliable Aviation) as a proof of concept for a larger multicopter with up to 25 kg take-off weight and 1.5–5.5 kg payload capacity. Designed for educational and demonstration purposes, it is mounted on a gimbal to enable stabilized flight in a safe, constrained environment, allowing real-time observation of embedded flight control.

The system demonstrates key multicopter technologies such as real-time processing, sensor-based stabilization, digital motor control, and wireless telemetry. Its flight-control platform is based on an Infineon AURIX TC375 LiteKit running FreeRTOS. A BMI088 IMU and DPS368 pressure sensor provide data for stabilization and state estimation, while motors are controlled via the fast and reliable DSHOT600 protocol.

A custom telemetry framework based on DroneBridge connects a Node.js web server via WiFi to an XIAO ESP32-C3, which communicates with the controller over UART. This enables real-time monitoring, diagnostics, and efficient parameter tuning during testing and demonstrations.
