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.

Assembling the drone

As predicted, our retractable landing gear has not arrived yet. Not only that, they are having issues in customs. Good for us! We thought ahead and bought temporary landing gear; $20.99 well spent!

So, here's a glimpse of what our assembled drone looks like (with temporary landing gear):

Let's take a quick look at the building techniques on a multicopter drone.

Too many freakin' wires!

That thing looks like a mess, doesn't it? It's not. Cable management is the key. You don't want any wires in danger of obstructing (or even breaking) propellers. That spells instant crash. The following image shows how the wires to the ESCs and motors are routed under the airframe and bundled:

Not only that, but electromagnetic (EM) interference is your enemy in the air. It can completely disrupt your video, telemetry, GPS, or even control signals. So never wrap your cables in circles. Instead, notice that they're wrapped up in figure-eights (especially power leads).

Since we're on this angle...
