When i run the rviz, it is publishing the ros topic /move_base_simple/goal. I have a robot which is subscribing the topic /medicbot/move_base_simple/goal from a move base node. How do i remap or rename the topic /move_base_simple/goal which is published from the rviz node?

<remap from="/move_base_simple/goal" to="/medicbot/move_base_simple/goal"/> is not working. i.e still same topic is comming.

Please detail exactly what you launch (i.e. the full launch file etc..) because with this launch file :

<launch>
    <node name="rviz" pkg="rviz" type="rviz">
        <remap from="/move_base_simple/goal" to="/medicbot/move_base_simple/goal"/>
    </node>
</launch>

It worked propperly so you might be doing something wrong, but not providing enough data for us to help you.

You can edit the launch file and use the remap tag as mentioned by @Delb, however if you prefer to use Rviz itself, this is how to do it:

Open rviz. Right click on 2D Nav Goal
Then select Tools properties
Enter the correct the topic in the 2D Nav Goal topic section
Close the tool properties window

If you want to save your configuration for later use:

Go to File->Save Config to save your rviz configuration
