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! |
