Turtlebot URDF in Rviz Loading problem on ros by exmaple groovy

[Lili Meng]

Hey,

         I just followed the instructions in the book of ROS by Example Groovy, but the turtlebot robot model cannot be displayed in Rviz.

         When I execute :
 

         $ roslaunch rbx1_bringup fake_turtlebot.launch

         The errors are following:
        ERROR: cannot launch node of type [robot_state_publisher/robot_state_publisher]: can't locate node [robot_state_publisher] in package [robot_state_publisher]

        For executing
 
        $ roslaunch rbx1_nav fake_move_base_blank_map.launch
      
        ERROR: cannot launch node of type [map_server/map_server]: can't locate node [map_server] in package [map_server]
        ERROR: cannot launch node of type [move_base/move_base]: can't locate node [move_base] in package [move_base]

       Can anyone provide some suggestions to solve this problem?

     Thanks a lot!

Cheers,
Lili

Hi Lili,

It sounds like you do not have your ROS_PACKAGE_PATH set correctly.
Please post back the output you get when you run the command:

$ env | grep ROS
