Designing Purpose-Built Drones for Ardupilot Pixhawk 2.1

By: Ty Audronis

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.

Planning and limitations

"A man's got to understand his limits," said Clint Eastwood in one of the famous Dirty Harry movies. The same philosophy is true when designing any drone. It's always good to have more capability than is truly required. However, you certainly may consider bringing it down a notch or two in practice. You'll see what we mean in a moment.

Identifying the components

The three types of components we're going to be interfacing with on the car are the Electronic Speed Controller (ESC), receiver, and servo(s).

Most RC cars only have one servo (to steer the wheels), but sometimes multiple servos exist (for example, four-wheel steering). We'll worry about the servo later. After all, we don't need to actually get at the servo. We just need its plug (which will be attached to the receiver). Servo wires are very easily identified. They are always three wires and are either colored in a white-red-black or yellow-red-black color scheme.

The ESC is also easily identified as it is where...
