webots_ros2_driver

[ntukenmez3]

Hi all, we would like to implement our controller developed by our team on CF2 simulator. We got the following error, could you help us to get rid of that problem, thanks.

~/webots_ros2/webots_ros2_mavic/launch$ ros2 launch ~/webots_ros2/webots_ros2_mavic/launch/robot_launch.py

Did you explicitly installed the webots_ros2_driver module as explained in the documentation?

Thanks for reply, what does ‘explicitly’ mean, it was installed on the computer, how can I show that it was installed on the computer, if you give me some recommendations, I can share it here, thanks. Get Outlook for iOS<https://aka.ms/o0ukef>

The following example as in ROS2-Webots tutorial. However, it is still same problem.

**ntukenmez3@ae-icps-407120:~/ros2_ws$** ros2 launch my_package robot_launch.py
