I created a gedit file and copy pasted the line, but I still can't launch this command.

Please post your launch file.

I have launched that file succesful! You must type cd .. to come back home in terminal and type roslaunch command here. My launch file 's type is XML. You can create a XML file by copy from other location.

Hi, I encountered similar situation as you in the beginning. On the terminal that you are launching turtlemimic.launch, did you do the following:

cd ~/catkin_ws
source ./devel/setup.bash

Finally, roslaunch your turtlemimic.launch file? Previously I couldn't launch, after I did this, it worked. Hope it works out well for you!

Yes i did that but I still get the same error, is it suppose to be an xml file or a plain text?

His question states, that he has done these commands and the error if he wouldn't would be different.

XML of course

How do I make a xml file or convert the plain text to xml

HelpwithUbuntu ( 2014-08-14 06:57:52 -0600 )edit

Post your launch file

BennyRe ( 2014-08-14 06:59:08 -0600 )edit

The tutorials says nothing about making an xml file, it just says create a launch file called turtlemimic.launch and paste the following. I copy pasted the text into gedit and saved it.

Are you some how familiar with XML?

I have gedit already installed, I don't understand " Rename it with .launch extension"?

I copy pasted the line,

 <launch> 
     <group ns="turtlesim1">    
 <node pkg="turtlesim" name="sim" type="turtlesim_node"/>
     </group>     
 <group ns="turtlesim2">    
 <node pkg="turtlesim" name="sim" type="turtlesim_node"/>     
 </group>     
 <node pkg="turtlesim" name="mimic" type="mimic">     
 <remap from="input" to="turtlesim1/turtle1"/>     
 <remap from="output" to="turtlesim2/turtle1"/> 
     </node>     
 </launch>

I saved it to home/pc/catkin_ws/src/beginner_tutorials/launch but it said I didnt have permission so I sudo it and it saved then but its not an xml file its a plain text file,

I do I save it in XML?
