2016-12-14 21:20:04 -0500	answered a question	When run rbx1_nav, and rviz :fixed frame :fixed frame [map] do not exist Self-answering again...: Found this tool is quite useful: roswtf. It tells me that my ROS_HOSTNAME is not set correctly. I just changed my IP and my hostname to this machine, so that's the reason. Suggestion would be: change your IP address in /etc/hosts and /etc/network/interfaces. And make sure in the ~/.bashrc your IP address is correct. For a single machine, suggest your IP address is set to 127.0.0.1.

2016-12-14 21:12:11 -0500	asked a question	When run rbx1_nav, and rviz :fixed frame :fixed frame [map] do not exist Hi,everyone. I install ros-by-exanple-indigo code on my computer.And I prepare to test fake robot simulator.However,Once I run the .launch file there will be a mistake in rviz.See follow. run command: `roscore` and `roslaunch rbx1_bringup fake_turtlebot.launch` Then: `rosrun rviz rviz -d 'rospack find rbx1_nav' /sim.rviz` then there's a mistake in rviz, `Global Status ：error fixed frame :fixed frame [map] do not exist` (the node works fine, as I publish the command to it and it can show it moves from the command line screen. So there should be some problems with the rviz I guess.) What direction should I go? Thanks.

2016-12-01 02:11:38 -0500	commented question	Cmake error:Workspace contains non-catkin packages in it self-answering: http://answers.ros.org/question/21299... Here someone has the same problem, maybe I should create another individual workspace for package I want to use.
2016-12-01 02:06:42 -0500	asked a question	Cmake error:Workspace contains non-catkin packages in it I'm new in ROS. And today when I started to install ROS_adruino_bridge, this error happens. I have searched on the website for this kind of errors, but have no results yet. Did anyone have this kind of problem before? Any suggestions if I cannot use catkin make in my workspace or how can I configure to solve this problem?

Any suggestions?
