Drone tutorial

This tutorial aims to provide guides on building a drone from kits and ending at controlling drones in experiments.

Main contents

1 Simulation

1.1 ROS1

1.1.1 single quadrotor with PX4 and Ardupilot in ROS

It explains how to install and configure PX4 or Ardupilot, ROS and ROS packages for ROS-Gazebo simulation.

• Single drone with PX4

  • Set up PX4, ROS noetic and mavros shows how to simulate a single quadrotor with the PX4 firmware in Gazebo.
  • Run controller in ROS-noetic-Gazebo simulation for PX4 demonstrates how to use a controller in ROS to controller a single quadrotor with the PX4 firmware in Gazebo.

• Single drone with Ardupilot

  • Set up Ardupilot, ROS noetic and mavros explains the steps to simulate a single quadrotor with the Ardupilot firmware in Gazebo.
  • [Run controller in ROS-Gazebo simulation for Ardupilot] ##TODO

1.1.2 Simulation for multiple quadrotors with PX4 and Ardupilot in ROS ##TODO

• Multiple drones with PX4
• Multiple drones with Ardupilot

1.1.3 Simulation uding Docker

• PX4 with Docker
  • PX4 with single quadrotor ROS
• Ardupilot with Docker

1.2 ROS2

For ROS2, only Docker approaches is shown as the author feels tired of configuring environment especially with poor documentation provided by XX.

1.2.1 single quadrotor with PX4 and Ardupilot

• PX4 with single quadrotor
• Ardupilot with single quadrotor

2 Experiment preparation

2.1 Assembly drones

1. Build Holybro X500 kit
2. Build TransTEC Lightning X Lite with Kakute

2.2 Configure and tune autopilot for manual flight

1. PX4
2. Ardupilot
3. Betaflight

2.3 ESP32 WiFi telemetry - DroneBridge

1. Ardupilot

2.4 Onboard computer setup

It demonstrates steps to add an onboard computer to a drone. It includes how to power it within the power system of Pixhawk and how to enable ROS communication among it, Pixhawk and base station.

1. Set up onboard computer
   • ROS1: Set up Raspberry Pi
   • ROS2: Set up Raspberry Pi
2. Enable communication between onboad computer and autopilot
   • Set up communication between Pi and Pixhawk with PX4
3. Enable communication between onboad computer and base station in ROS through WIFI
   • Set up ROS communcation between onboard computer and base station through WIFI

3 Drone controllers

1. Use mavros_controller It explains how the drone control package mavros_controller is designed and what to do to implement it in experiment.

4 Experiment in cases

4.1 Indoor flights with VIcon

1. Set up and use Vicon system It gives an idea of how to use a motion capture system for drone experiments.
2. Configure PX4 using Vicon It gives an idea of how to use a motion capture system for drone experiments.

4.2 Add functional payloads and sensors

1. Add more devices to drone in experiment It suggests what to do if more additional devices are to be added to a drone to extend its functions.

PX4 And Ardupilot

1. ROS2 and PX4 It aims to move every drone techniques in ROS to ROS2.

2. Ardupilot

   • Introduction of Ardupilot
   • Ardupilot and ROS2
