Your problem is that the "Quaternion Not Properly Normalized". A Quaternion (your rotation) must have a norm of 1 (x2+y2+z2+w2==1) which is obviously not true for your quaternion. You can use these functions to create a valid quaternion from RPY: http://wiki.ros.org/tf/Overview/Data%20Types

Your problem is that the "Quaternion [is] Not Properly Normalized". A Quaternion (your rotation) must have a norm of 1 (x2+y2+z2+w2==1) which is obviously not true for your quaternion. You can use these functions to create a valid quaternion from RPY: http://wiki.ros.org/tf/Overview/Data%20Types

 x**2+y**2+z**2+w**2==1

which is obviously not true for your quaternion. You can use these functions to create a valid quaternion from RPY: http://wiki.ros.org/tf/Overview/Data%20Types
