Thanks Tucker, I am planning to publish static_transform_publisher for each sonar element. I am planning to have sonar_ranges listener, which will publish 8 topics, each corresponding to one element. Each topic now represent distance observed from base frame of robot. Use this data to generate a point cloud and pass this to navigation stack. I hope this will work. regards Nitin -- View this message in context: http://ros-users.122217.n3.nabble.com/sonar-data-for-navigation-stack-tp986448p989172.html Sent from the ROS-Users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
