Hello everyone!
I am new to Ros/Gazebo/PX4 stack, and am facing some issues. I have installed PX4/Ros/Gazebo on a fresh Ubuntu 18.04 and I am trying to run the simulation examples, using make px4_sitl on it.
When I run the gazebo simulation on it, by typing in make px4_sitl gazebo, Gazebo launches but the pxh shell doesn’t come up. I tried the same with jmavsim using make px4_sitl jmavsim, but in that case the pxh shell came and it performed a takeoff well.
I have installed/reinstalled PX4/Ros/Gazebo multiple times now, and am still wondering what could be the issue now.
My environment variables are set as below:
source ~/PX4-Autopilot/Tools/setup_gazebo.bash ~/PX4-Autopilot ~/PX4-Autopilot/build/px4_sitl_default
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/PX4-Autopilot
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/PX4-Autopilot/Tools/sitl_gazebo
export GAZEBO_PLUGIN_PATH=$GAZEBO_PLUGIN_PATH:/usr/lib/x86_64-linux-gnu/gazebo-9/plugins
export GAZEBO_MODEL_PATH=$GAZEBO_MODEL_PATH:/home/major/catkin_ws/src/px4_fast_planner/models
The logs for the gazebo simulation are below. I have to interrupt the execution, because nothing happens, even after 10-20 minutes:
