Ardupilot-SITL-Gazebo-Setup

Summary: This set of instructions guides you through the installation of Ardupilot and Software-in-the-Loop (SITL) along with Gazebo simulation. It involves cloning a repository, setting up Ardupilot, configuring Gazebo, and testing the integration of Ardupilot with Gazebo.

Requirements:

• Ubuntu 20.04 or 22.04
• Graphics card recommended

Instructions:

1. Install Ardupilot & SITL:
   • Setup Ardupilot & SITL

     git clone https://github.com/Sky-Labs-Research/Ardupilot-SITL-Gazebo-Setup.git
     cd Ardupilot-SITL-Gazebo-Setup
     ./setup_ardupilot.sh

   • Test Ardupilot SITL

     cd ~/ardupilot/ArduCopter
     sim_vehicle.py -w
     sim_vehicle.py --console –map

2. Install Gazebo:
   • Setup Gazebo

     ./setup_gazebo

   • Test Gazebo

     gz sim -v4 -r shapes.sdf

3. Install Ardupilot + Gazebo:
   • Setup Ardupilot Gazebo

     ./setup_ardupilot_gazebo

   • Test Ardupilot and Gazebo

     # In one console
     gz sim -v4 -r iris_runway.sdf
     # In another console (CTRL+T Opens a new console tab)
     sim_vehicle.py -v ArduCopter -f gazebo-iris --model JSON --map --console
     # Arm and Take off
     # STABILIZE> mode guided
     # GUIDED> arm throttle
     # GUIDED> takeoff 5

No Script (Manual) Instructions:

1. Install Ardupilot & SITL:

   • Run the following commands:

     sudo apt-get update
     sudo apt-get install git
     sudo apt-get install gitk git-gui
     git clone --recurse-submodules https://github.com/ArduPilot/ardupilot.git
     cd ardupilot
     Tools/environment_install/install-prereqs-ubuntu.sh -y
     . ~/.profile

2. Setting up SITL:

   • Run the following commands:

     cd ~/ardupilot/ArduCopter
     # Wipe EEPROM
     sim_vehicle.py -w
     # Test
     sim_vehicle.py --console –map

3. Install Gazebo:

   • Run the following commands:

     sudo apt-get update
     sudo apt-get install lsb-release wget gnupg
     sudo wget https://packages.osrfoundation.org/gazebo.gpg -O /usr/share/keyrings/pkgs-osrf-archive-keyring.gpg
     echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/pkgs-osrf-archive-keyring.gpg] http://packages.osrfoundation.org/gazebo/ubuntu-stable $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/gazebo-stable.list > /dev/null
     sudo apt-get update
     sudo apt-get install gz-garden
     . ~/.profile

4. Setup Ardupilot with Gazebo:

   • Run the following commands:

     # Check Gazebo
     gz sim -v4 -r shapes.sdf
     sudo apt update
     sudo apt install libgz-sim7-dev rapidjson-dev -y
     cd ~
     git clone https://github.com/ArduPilot/ardupilot_gazebo
     cd ardupilot_gazebo
     mkdir build && cd build
     cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo
     make -j4
     export GZ_SIM_SYSTEM_PLUGIN_PATH=$HOME/ardupilot_gazebo/build:$GZ_SIM_SYSTEM_PLUGIN_PATH
     export GZ_SIM_RESOURCE_PATH=$HOME/ardupilot_gazebo/models:$HOME/ardupilot_gazebo/worlds:$GZ_SIM_RESOURCE_PATH
     echo 'export GZ_SIM_SYSTEM_PLUGIN_PATH=$HOME/ardupilot_gazebo/build:${GZ_SIM_SYSTEM_PLUGIN_PATH}' >> ~/.bashrc
     echo 'export GZ_SIM_RESOURCE_PATH=$HOME/ardupilot_gazebo/models:$HOME/ardupilot_gazebo/worlds:${GZ_SIM_RESOURCE_PATH}' >> ~/.bashrc
     . ~/.profile

5. Test Gazebo SITL Plugin:

   • Run the following commands:

     # In one console
     gz sim -v4 -r iris_runway.sdf
     # In another console (CTRL+T Opens a new console tab)
     sim_vehicle.py -v ArduCopter -f gazebo-iris --model JSON --map --console
     # Arm and Take off
     # STABILIZE> mode guided
     # GUIDED> arm throttle
     # GUIDED> takeoff 5
