Hi all, looking for your help and thanks in advance. I have searched online but cannot find anything related.

I am complete new to ROS and TurtleBot. I have installed the Ubuntu 14.04 on both my remote PC and the notebook of TurtleBot. Following the tutorials, I have finished everything until the "A First Interaction". The connection is through wifi, have tested in the TurtleBot bringup and PC bringup, no issues.

In this "A first Interaction", when i try command rqtremocon, I got "ImportError: No module named roconqt_library.utils" , and details are:

RosPluginProvider.load(roconremocon/Rqt Remocon) exception raised in _builtin.import(roconremocon.rqtremocon, [RqtRemocon]): Traceback (most recent call last): File "/opt/ros/indigo/lib/python2.7/dist-packages/rqtgui/rospluginprovider.py", line 77, in load module = _builtin.import(attributes['modulename'], fromlist=[attributes['classfromclasstype']], level=0)

ImportError: No module named roconqtlibrary.utils

I run this command on the remote PC after "ssh +X name". +X is for the display setting, without the +X i got "rqt_remocon: cannot connect to X server". When I run this command on the Turtlebot, it returned the same error.

Does anyone have some clues about what problem this is. Thanks.
