Installation Guide

Installation process for simulation and execution in ROS and Gazebo

Developed by William Chamorro PhD. for the GI-ATA research group

ArduCopter and ArduPilot are two open-source projects for controlling autonomous vehicles. ArduPilot is the main project, encompassing a wide range of vehicles including planes, helicopters, rovers (land vehicles), and boats. ArduCopter, on the other hand, is a specific part of ArduPilot dedicated to controlling drones or multirotor aircraft such as quadcopters and hexacopters.

Both projects, ArduCopter and ArduPilot, offer open-source software and hardware that enables enthusiasts and developers to create and control their own autonomous vehicles. They provide navigation functions, flight control, mission planning, among others, allowing for extensive customization and adaptation to different types of vehicles and specific needs.

This guide was tested in standard CPU with ROS-noetic and Ubuntu focal

The following sections show what tested open source nodes to install in order to have a successful Arducopter - ROS integration

Installation of QGroundControl

QGroundControl is a ground control station software used to control and monitor unmanned vehicles, particularly drones and autonomous vehicles. It's an open-source application that provides a user-friendly interface for configuring vehicles, planning missions, monitoring telemetry data (like altitude, speed, and battery status), and controlling the vehicle during flight.

QGroundControl supports various types of vehicles and is compatible with different autopilot systems, including ArduPilot and PX4, offering a comprehensive set of tools for mission planning, flight control, and vehicle setup. It's a critical component in the operation of unmanned systems, allowing users to interact with and manage their vehicles efficiently and safely from the ground. Te following summarize how to install this app.

Create a folder and download QGroundControl

mkdir QGround && cd QGround
sudo usermod -a -G dialout $USER
sudo apt-get remove modemmanager
wget https://s3-us-west-2.amazonaws.com/qgroundcontrol/latest/QGroundControl.AppImage

Screenchot of the downloading process

Change permissions and execute for testing

chmod +x ./QGroundControl.AppImage 
./QGroundControl.AppImage

That is how QGropundControl looks like

Installing Gazebo and ArduPilot Plugin

Robot simulation is an essential tool in every roboticist's toolbox. A well-designed simulator makes it possible to rapidly test algorithms, design robots, perform regression testing, and train AI system using realistic scenarios. Gazebo offers the ability to accurately and efficiently simulate populations of robots in complex indoor and outdoor environments.

This plugin was aimed for Gazebo 11

Gazebo 11 installation

This section is intended in case we do not have installed Gazebo 11. Recall that Gazebo installs along ROS noetic in the desktop-full version.

Update packages before installing

sudo apt-get update
sudo apt-get upgrade

Setup your computer to accept software

sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'

Setup keys

wget http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -

Reload software list

sudo apt update

Install Gazebo

sudo apt-get install gazebo11 libgazebo11-dev

Gazebo plugin installation

Update packages before installing

sudo apt-get update
sudo apt-get upgrade

Download the APM plugin

cd ~
git clone https://github.com/khancyr/ardupilot_gazebo.git

Compile the package

cd ardupilot_gazebo
mkdir build
cd build
cmake ..
make -j4
sudo make install

Set up bashrc

echo 'source /usr/share/gazebo/setup.sh' >> ~/.bashrc
echo 'export GAZEBO_MODEL_PATH=~/ardupilot_gazebo/models' >> ~/.bashrc
. ~/.bashrc

If everything was done correctly we will be able to launch the plugin but it will not fly yet.

Terminal 1 type,

gazebo --verbose ~/ardupilot_gazebo/worlds/iris_arducopter_runway.world

Install Ardupilot and MAVProxy Ubuntu

MAVProxy stands for "MAVlink Proxy." It's a versatile command-line ground control station (GCS) used primarily with ArduPilot, which is a popular open-source autopilot software. MAVProxy acts as an intermediary communication system between the ground control station and the vehicle's autopilot, allowing users to interact with the vehicle using a command-line interface.

Clone ArduPilot

cd ~
sudo apt install git
git clone https://github.com/ArduPilot/ardupilot.git
cd ardupilot

Install dependencies

sudo apt-get update –y
sudo apt-get install -y python3-testresources
cd ardupilot
Tools/environment_install/install-prereqs-ubuntu.sh -y

If all dependencies were successfully installed you will see the following message.

Successfully installed dependencies

Reload the profile

. ~/.profile

Checkout for the most stable version

git checkout Copter-4.0.4
git submodule update --init --recursive

If git submodule update fails

git config --global url.https://.insteadOf git://

Test installed dependencies

cd ~/ardupilot/ArduCopter
sim_vehicle.py -w

ArduCopter Execution

Install MAVROS

MAVROS stands for "MAVLink Robot Operating System." It's a middleware that acts as a bridge between MAVLink based autopilots, like the ones used in ArduPilot or PX4, and the Robot Operating System (ROS).

Install extras

sudo apt-get install ros-noetic-mavros ros-noetic-mavros-extras

Then install GeographicLib datasets

wget https://raw.githubusercontent.com/mavlink/mavros/master/mavros/scripts/install_geographiclib_datasets.sh
./install_geographiclib_datasets.sh

Install the ros node

We use catkin build instead of catkin_make

Install python catkin tools

sudo apt-get install python-catkin-tools python-rosinstall-generator -y

Create the workspace

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws
catkin init
wstool init src

Install MAVROS

rosinstall_generator --rosdistro kinetic mavlink | tee /tmp/mavros.rosinstall
wstool merge -t src /tmp/mavros.rosinstall
wstool update -t src -j4
rosdep install --from-paths src --ignore-src -y

We asume that rosdep is enabled in your computer, if not do this before rosdep install

rosdep init
rosped update

Install Geographic lib datasets

./src/mavros/mavros/scripts/install_geographiclib_datasets.sh

Remember to use this on each window that runs a ROS node

source devel/setup.bash

Clone simulation packages

cd ~/catkin_ws/src
git clone https://github.com/Intelligent-Quads/iq_sim.git
echo "GAZEBO_MODEL_PATH=${GAZEBO_MODEL_PATH}:$HOME/catkin_ws/src/iq_sim/models" >> ~/.bashrc

Compile all packages

catkin build

Update global variables

source ~/.bashrc

If all packages were successfully compiled you will see this

prueba

roslaunch iq_sim runway.launch

/ardupilot/ArduCopter$ sim_vehicle.py -v ArduCopter -f gazebo-iris --console
