Setup and launching the simulation environment:-

  • Clone the repo, build in your preferred system and add the following lines in your bashrc.
source ~/{name_of_workspace}/devel/setup.bash

source ~/{name_of_workspace}/src/PX4-Autopilot/Tools/setup_gazebo.bash ~/{name_of_workspace}/src/PX4-Autopilot/ ~/{name_of_workspace}/src/PX4-Autopilot/build/px4_sitl_default >> /dev/null

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/{name_of_workspace}/src/PX4-Autopilot

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/{name_of_workspace}/src/PX4-Autopilot/Tools/sitl_gazebo

  • For making gazebo work with PX-4 autopilot
cd ~/{name_of_workspace}/src/PX4-Autopilot/
make px4_sitl_default gazebo
  • Command roslaunch flying_skylark flying_square.launch will launch the gazebo world along with the PX-4 autopilot.
