Hi everyone
When trying to start the navigation I get the following error
Have I made any mistake by following the exercises steps?
Thanks in advance
Hi Laura,
Looks like there’s a problem with the instructions causing this error. Try removing this line from your start_navigation.launch file:
<!-- Turtlebot3 -->
<include file="$(find turtlebot3_bringup)/launch/turtlebot3_remote.launch" />
This file is being included twice in start_navigation.launch, because it’s included by start_localization.launch, which is also included in start_navigation.launch.
turtlebot3_remote.launch contains the node /robot_state_publisher. Therefore, if it’s included more than once, this node will be replicated and will generate this kind of error.
We’ll fix this error in the notebook.

Hello @lfernandez ,
Now the error is telling you that you are launching the map_server node multiple times. You are launching it inside this launch file (lines 8 to 10) and probably also inside the start_localization.launch. So you should remove (or comment) one of them.
Best,
