Hi, which version of ROS2? Which branch of tello_ros?

[Efesendil]

ROS2 foxy, and /tello_ws/src/tello_ros/tello_gazebo

[clydemcqueen]

Try sudo apt install ros-foxy-gazebo-ros*

[Efesendil]

Hello again sir, I have successfully compiled the workspace, thank you. But i can't use ros2 launch: And ros2 run doesn't work also. It is a simple question but I can't find anything about it, you have any idea about it ?

~$ ros2 launch tello_gazebo simple_launch.py usage: ros2 [-h] Call ros2 <command> -h for more detailed usage. ... ros2: error: argument Call ros2 <command> -h for more detailed usage.: invalid choice: 'launch' (choose from 'control', 'daemon', 'extension_points', 'extensions', 'node', 'param', 'pkg', 'run', 'service')

It seems that your ROS2 Foxy install is somehow incomplete. The typical way to install Foxy is sudo apt install ros-foxy-desktop. That should add the "launch" verb the ros2 CLI.

You may be able to fix this by running sudo apt install ros-foxy-launch*.

If you are still running into problems you might benefit from uninstalling Foxy and starting over.

If you're new to ROS2 you may enjoy the tutorials: https://docs.ros.org/en/foxy/Tutorials.html

Thank you, programs are running without any problem after these commands !! I just have few questions.

1) Im using a virtual machine (parallels), I have connected to drone wifi from my main system but i guess it doesnt connect from ubuntu. How can i figure it out ?

2) what im exactly trying is to connect ros2 to matlab, so i need to see published and subscribed topics. I didnt find odometry messages and i cant see message descriptions when i type, ex : ros2 topic echo /cmd_vel. Do you know why?
