This is useful to make the /odom to /base_link transform that move_base uses more reliable, especially while turning. This walk-through assumes you have IMU data and wheel encoder data publishing to …

EKF kicks off, gets a single IMU measurement from, e.g., imu3. So its first output has a pose and position of 0, with whatever angular velocity was in that message. navsat_transform_node is ready, and gets all its input data, including that first pose from the EKF (i.e., input 3 above). That pose is 0. EKF fuses pose from some other source.-if u don't know enough about rosserial, follow this tutorials (http://wiki.ros.org/rosserial/Tutorials)-how to publish the ticks of encoders on ros (https:/...Hi all, I am using robot_localization and navsat_transform to fuse RTK gps (dual antenna so we have orientation) and imu data. The issue that I am seeing is that when I run a bagfile twice with the same recorded input topics, I get slightly different outputs. Since the inputs are the same and the parameters for the EKF are the same, I would expect the output being exactly the same.Using error-state Kalman filter to fuse the IMU and GPS data for localization. - ydsf16/imu_gps ... ros_wrapper. ros_wrapper ... package.xml View all files.
