Hi! I'm beginner of ROS. So, I want to practice the ROS through the Turtlebot! But, it is very difficult!

I'm proceding the "TurtleBot Bringup" session. The first, I typed "roslaunch turtlebot_bringup minimal.launch" in remote PC followiwng the manual. But it occured, "ERROR : unable to contact ROS master at [http:// my_IP] The traceback for the exception was written to the log file".

What should I do?

Actually, I cannot assure that I did well the precedent procedure! Help me!

I'm a beginner too :), I think you have to run this command on your turtlebot computer by remoting in (telenet, ssh etc) and not your remote computer. Also make sure you can ping the turtlebot IP and have set the environmental variables.
