Problem with ROS Navigation Package (IMU GPS) Fusing GPS in robot_localization. Imu values not being filtered properly. robot_localization - IMU orientation query. robot_localization drift. How to calculate covariance matrix? SLAM with cartesian point cloudsNever face this issue when using ekf_node in ROS1, but faced this issue when porting to ROS2. Best, Samuel. Operating System: Ubuntu 20.04 Installation type: $ sudo apt install ros-foxy-robot-localization Version or commit hash: ros-foxy-robot-localization is already the newest version (3.1.1-1focal.20220204.181349) Hi Above are my robot ...After a quick look at the raw data, I see your IMU data is in the odom frame. I have an open issue (issue #22) for fixing the way I'm handling the IMU frame.For now, if you change the frame_id of your IMU data to base_link, or give it its own "imu" frame and then make a static identity transform from base_link to imu, it will stop trying to apply its own transform.The ekf_localization_node however seems to "filter" the odometry in a weird way: The x and y position moves in the right direction, but only by half the distance of what it should do, whereas the yaw movement is scaled to maybe a 100th of it's original amount. ...

Hi there, I am trying to fuse GPS with IMU information with ekf_localization_node. For now I have tied by map and odom frames to be always the same, so I assume that GPS is giving absolute map positions, and report them in the map frame. I am confused about the IMU though: it's heading estimate should be in the map frame as it's ...Apr 19, 2021 ... ROS Developers Live-Class #51: How to fuse Odometry & IMU using Robot Localization Package. The Construct•38K views · 7:38. Go to channel ...Ok so i found a workaround. instead of using $ sudo apt-get install ros-kinetic-robot_localization I went into my catkin_ws src folder and opened a terminal. then i entered:Now the Problem: If I record the exact same data from the robot with a rosbag2 and than try to calculate Robot_localization on my VM the estimated position goes crazy (values over 40000 in x for example). I record everything with the rosbag, so there is no difference except for the not running ekf node of course.
