2016-02-23 02:30:16 -0500 asked a question publishing goal with a different frame_id

Hi, I'am using the demo.launch, after setting my arm with setup_assistant. I would like to make the arm floats, to simulate it is attached to an underwater rov, and test the capability of my algorithm to reach the goal. How can I publish my goal with respect to a fixed frame that is different from the root frame of the arm?

thank you

With world_frame = map the ekf should publish the map --> odom transform. What happens is that it publishes odom->base_link transform instead. I am sure that EKF was publishing the odom->base_link transform, I checked with tf_monitor, rviz, rostopic echo...

Hello, currently I have switched to the second mode, that is working fine. By the way, I am sure that EKF was publishing the odom->base_link transform, I checked with tf_monitor, rviz, rostopic echo... I will post other data as soon as possible.

2015-09-17 05:01:30 -0500 asked a question robot_localization: WARNING: could not obtain transform from map to odom. Error was Unable to lookup. Could not transform measurement into odom. Ignoring...

hello, I have a nomadic scout 2-wheel robot with a kinect sensor that is able to navigate inside a map by means of the ros (groovy) navigation stack. An odometry topic is provided by the robot, and the /odom --> /base_link transform too. I want to feed the ekf_localization node with the position the robot provided by our Vicon MoCap system, in order to fuse it with the odometry information. I have a map, provided by a map server, and the robot pose coming from Vicon is published as a PoseWithCovarianceStamped topic, with ref_frame_id = 'map'. So I want to use ekf_localization node in the second mode, with world_frame = 'map', and I expect the /map --> /odom tf from ekf_localization node. What I see is that ekf_localization node is publishing /odom --> /base_link transform too, overwriting the odometry-generated transform each other. So the ekf_localization node seems working in the first mode, and it does not sense the /odom --> /base_link tf, already published by the robot.

this is my ekf launch file:
