How can I transform it into quaternion? Thanks. I am aware of those methods. So I am doing it something like this and I hope that this does the job of transforming RPY into Quaternion. Is there any other way to do this? tf:: Quaternion rotation_rpy; rotation_rpy.setRPY(x,y, theta); geometry_msgs::Quaternion rotation_quat; tf::quaternionTFToMsg(rotation_rpy, rotation_quat);  2015-03-17 03:53:41 -0500 received badge ● Notable Question (source) 2015-03-16 13:37:34 -0500 received badge ● Student (source) 2015-03-16 13:10:23 -0500 received badge ● Popular Question (source) 2015-03-16 09:41:25 -0500 asked a question Suppose I have an orientation as roll, pitch, yaw. How can I transform it into quaternion? I am trying to represent a point (x,y,theta) as a quaternion. What is the easiest way to do that? 2014-12-04 04:20:23 -0500 commented answer Build of Win_Ros with Visual Studio 2013 for Kinect2 usage ^I cannot see your post. 2014-12-04 04:10:33 -0500 answered a question what are the differences between "name" and "type" in roslaunch? The easiest way to find out what to initialize in the type is to go to your CMakeLists.txt. Find the line that says something like add_executable(blah_blah src/whatever.cpp) then blah_blah is the type. Another way is to cd to your /devel/lib/ folder, dig into your package and there you will see the executables(probably, in green). 2014-11-21 08:05:25 -0500 answered a question need help converting lat-long coordinates into meters I am implementing something similar. You should probably look into http://docs.ros.org/hydro/api/gps_com... I think this is what you are looking for "static void LLtoUTM (const double Lat, const double Long, double &UTMNorthing, double &UTMEasting, std::string &UTMZone)" so just pass parameters and then this will do the rest. :) Hope this helps. :) 2014-10-31 04:20:59 -0500 answered a question Build of Win_Ros with Visual Studio 2013 for Kinect2 usage A group of students from university of Bremen have come up with the driver that works well on 12.04 and 14.04 meaning for both hydro and indigo. Here is the link to what they have done. It also has the link to their git repo. http://www.ros.org/news/2014/09/micro... 2014-10-31 04:20:27 -0500 commented answer Kinect 2? or keep Kinect 1 Is this the case still?
