Can you tell us what steps did you do? Can you explain to us more clear since we couldn't see what you did. Be sure to add details!

Hi,
I'm assuming you are trying to get the turtlebot3 repository from ROBOTIS to work. I see that there is a node called turtlebot3_obstacle_detection inside the turtlebot3_example package. First make sure you clone the correct repositories:
git clone -b dashing-devel https://github.com/ROBOTIS-GIT/turtlebot3
git clone -b dashing-devel https://github.com/ROBOTIS-GIT/turtlebot3_msgs
git clone -b dashing-devel https://github.com/ROBOTIS-GIT/turtlebot3_simulations
Once you have them cloned on your /src folder inside your workspace, compile and source your environment with
colcon build
. install/setup.bash
Once it's compiled, you can try launching the node instead of the launch file (sometimes, if a public repository indicates that is devel, then it might have things that are not working correctly yet):
ros2 run turtlebot3_example turtlebot_obstacle_detection
And that should run the node correctly. I also made this video that explains what I wrote above if you are interested:
