Overview of this book

The Ardupilot platform is an application ecosystem that encompasses various OS projects for drone programming, flight control, and advanced functionalities.The Ardupilot platform supports many Comms and APIs, such as DroneKit, ROS, and MAVLink. It unites OS drone projects to provide a common codebase. With the help of this book, you will have the satisfaction of building a drone from scratch and exploring its many recreational uses (aerial photography, playing, aerial surveillance, and so on). This book helps individuals and communities build powerful UAVs for both personal and commercial purposes. You will learn to unleash the Ardupilot technology for building, monitoring, and controlling your drones.This is a step-by-step guide covering practical examples and instructions for assembling a drone, building ground control unit using microcontrollers, QgroundControl, and MissionPlanner. You can further build robotic applications on your drone utilizing critical software libraries and tools from the ROS framework. With the help of DroneKit and MAVLink (for reliable communication), you can customize applications via cloud and mobile to interact with your UAV.

Recommended VTOL RTL procedure

There are several ways to handle RTL with a hybrid like this, but here's what I recommend:

  1. Head back (RTL) using the airplane RTL mode. This gets you to the vicinity quickly.
  2. Switch to QRTL when close to the home point. If Q_RTL_ALT, RTL_RADIUS, and Q_RTL_MODE are set, this happens automatically
  3. Switch to QLAND and again, if Q_RTL_ALT, RTL_RADIUS, and Q_RTL_MODE are set, this will happen automatically

I find this to be the most efficient procedure. No wasting battery time on circling, or other maneuvers. Just fly in, switch modes, and land.
