So for the usage without ROS I don't think quaternions are necessarily better but for the usage with ROS it saves you one or two steps.\r\n\r\nI don't have a real opinion on that to be honest as I don't use it much. How about both? :P\r\nIf a 3-tuple is given assume rpy and a 4-tuple is a quaternion?!"}}
