I also note that you are using ROS noetic; perhaps the package hasn't been updated to support it yet. In any case, the package author suggests that you can e-mail him directly in the README. …

EDIT: removing question about use_sim_time in ROS 2 in response to @Tully's point in the comments. … I was able to run your config from the command line in foxy: ros2 run robot_localization ekf_node --ros-args --params-file ekf_params.yaml I manually published messages to imu using the sample you provided …

I can answer more definitively if you provide the information I requested in the comment above, but I can probably guess what's wrong anyway. You have two_d_mode enabled, which means you need to provi …

I wrote the core filter classes to be ROS-agnostic, but then wrapped them in ROS-aware classes that take in messages, preprocess the data (transform into target frames, check for invalid messages, etc. …

You need a velocity reference. r_l is not good at working with only pose + acceleration data. It's going to be integrating the acceleration from the IMU and causing the velocity estimate to grow very …

The filter statement is just python, so you can use or: rosbag filter old_bag.bag new_bag.bag "topic == '/stereo/left/image_rect' or topic == '/stereo/right/image_rect' or topic == '/stereo/left/came …

Yes, that is what I'd expect to see. Your pose measurements will generally have a stronger effect on your pose estimate than your velocity measurements. This is because the pose measurements from SLAM …

EDIT: in the error in the image you posted (please post text in the future), ROS is telling you what it's unhappy about: you have two different nodes publishing the odom->base_link transform. …

(2) The UTM coordinates produced by the GPS are, of course, not in the assumed ROS frame. … Originally posted by Tom Moore on ROS Answers with karma: 13689 on 2013-02-26 Post score: 1 …

I found some examples online that use boost::bind, but rosmake is not happy with the syntax, and I'm beginning to wonder if they're from an older version of ROS. … Originally posted by Tom Moore on ROS Answers with karma: 13689 on 2013-07-23 Post score: 7 Original comments Comment by thebyohazard on 2013-07-24: A duplicate of my question. …

Does ROS internally do some kind of one-to-one mapping between topic types and callbacks, or is there clearly some kind of error in how I'm handling the subscription? … Originally posted by Tom Moore on ROS Answers with karma: 13689 on 2013-08-01 Post score: 0 Original comments Comment by thebyohazard on 2013-08-01: Nope, I use one cb for multiple subscribers in quite …

Ah, I wasn't watching rosbag. It was telling me that a topic that I thought was one type was actually another. It works now. Thanks! Originally posted by Tom Moore with karma: 13689 on 2013-08-01 Th …

I haven't formally announced this yet, but you might want to try this: http://wiki.ros.org/robot_localization It will let you choose to only use parts of your sensor messages. Originally posted by T …

If I understand what you're after, you just want to use point cloud data and ICP to generate odometry messages. You shouldn't need to do any scene reconstruction for this; just take in the PointCloud …

What I would like to do is create a ROS package that acts as a wrapper, so that all my other ROS packages can just list the wrapper package as a dependency, and all the include and library C++ flags that … Originally posted by Tom Moore on ROS Answers with karma: 13689 on 2014-04-08 Post score: 2 …
