To start up I'm trying to run Rviz on my remote pc but there's a step that gives me an error. By the way I'm following the steps on the following website |section 7|. http://emanual.robotis.com/docs/en/pl...
Something that might be useful to know
- I'm running melodic on remote pc, Ubuntu 18.04.

roslaunch turtlebot3_bringup turtlebot3_robot.launch
on my turtle pc.
- To begin with I run

on my remote pc so it recognizes my turtle pc. In this case I don't have too because I've permanently set the export settings. So the next step will be running roslaunch turtlebot3_bringup turtlebot3_remote.launch
on my remote pc but this step prints out this error on my terminal!
