2015-07-02 15:54:52 -0500	commented answer	how bagfile avoid to be rewritten No. I use it in program not terminal. Actually, in my program, I record two timestamps by myself and I just omit its timestamp. : ) Is it kind of cheating?
2015-07-02 12:43:59 -0500	answered a question	how bagfile avoid to be rewritten I find the solution. Just change the bag open mode as bag = rosbag.Bag('test.bag', 'a') Mode 'a' means add in the file.

2015-07-01 13:23:11 -0500	asked a question	how bagfile avoid to be rewritten When I try to use bag file to store data, I find the bag file only store the data that I write last time. Last time means the last time to open the bag file and write data. Anybody knows how to add data to bag file?

2015-06-18 13:44:14 -0500	commented answer	header of view controller Thank you very much. Actually, I only want to use the up to down view and not a 3D view. Anyway, thanks a lot.
2015-06-18 13:36:33 -0500	asked a question	header of view_controller I am using rviz to show the navigation map. Now I want to make the robot always in the middle of the map. I try to avoid plugin. So I try to use Viewcontroller::lookat and VisualizationManager::getCurrentViewController. But I am always wrong about the header and I don't know whether I can do this without using plugin (because I think plugin is too complicated).
