I am trying to use the turtlebot_follower for one of my project. When launch the turtlebot follower with the command

roslaunch turtlebot_follower follower.launch

I can find the node turtlebot_follower in list and also when i read the code in follower.cppit subscribes dept_image and publishes cmd_vel but the node is not actually subscribing or publishing anything. How can i get around this?

Maybe the topics are being remapped on the follower.launch file.

After running that launch file you can rosnode info /turtlebot_follower to see in which topics it advertises and subscribes.

@Kishore Kumar Is this still an open question or you solved it?
