Thanks Narasimhan, I went through the steps again and got the following: nitin@debian:/opt/ros/boxturtle/ros_tutorials$ roslaunch awesomeros robot.launch ... logging to /home/nitin/.ros/log/6063d75e-8ddd-11df-b52d-0022680fe838/roslaunch-debian-23983.log error loading tag: file does not exist [/opt/ros/boxturtle/ros_tutorials/awesomeros/navfn_params.yaml] XML is It is probably, tutorial do not instruct to create navfn_params.yaml file. I am not aware about functionality this file enables but if I remove the following line: from move_base.xml, example works very well. Probably you can include some explanation on this as well. I can visualized much better on my laptop than my desktop although both have identical setups, which ros proves are not! :) Also stage cosuming cpu increases on my laptop as well. I will dig deeper into it.
