  • Flight Controllers

    • PixHawk

      • off-the shelf piece of hardware/controller that can be bought off any website

    • ZeroPilot (ZP)

      • custom made/in-house flight controller built by electrical team

    • Sensors, etc

  • Jetson

    • hardware that runs all autonomy code (code ran on the actual drone)

    • essentially an advanced raspberry pi, but with additional hardware for ML models

    • contains computer vision python repository

    • geolocation - maps pixel coordinates to geographical coordinates

      • outputs “absolute” lattitude/longitude

      • given image with bounding box + information about drone state, gives lat/long. of landing pad (not sure about accuracy)

      • send to dronekit api - easy to communicate with pixhawk controller

      • MAVLINK, sends back to PixHawk which centers drone with Rgpilot

  • Descend the drone to 5-12 m above landing pad

  • Drivers

    • UART protocol allows 2 hardware devices to communicate

    • Dronekit → Pixhawk communication might need a driver
