Introduction to Drones

The UAV Ecosystem

Unmanned Aerial Vehicles (UAVs), commonly known as drones, involve complex flight dynamics and sophisticated telemetry systems.

Flight Stack

  • Flight Controller: The hardware (Pixhawk, Orange Cube).
  • Firmware: PX4 or ArduPilot.
  • Communication Protocol: MAVLink for telemetry and control.

Key Challenges

  • Stability: High-frequency PID loops for altitude and position hold.
  • Autonomy: GPS-denied navigation using optical flow or VIO (Visual Inertial Odometry).
  • Power Management: Optimizing thrust-to-weight ratios for longer flight times.
