I would like the turtlebot to autonomously navigate a space and update it's position based on AprilTag landmarks. It seems that the way to do this is to take advantage of a map frame.Similar to the question asked here with respect to fusing GPS and IMU sensor data when those are the only two sensors available. My question is with respect to creating the odom and map frames. Based on the dual_ekf_navsat_example, an ekf_localization_node1 fuses odom and IMU data inputs and generates an output odometry/filtered and creates the odom->base_link transform.

I'm using robot_localization ekf on ROS2 Foxy to fuse two odometry sources. I am working in 2D so only x, y and yaw is used and the two_d_mode is set to true. I was trying to use only the velocities because the best practice (told on the docu) is to fuse the velocity data if your odometry gives you both. If I do so the Filter doesnt output an ...Quick method : Launch these file like a normal .launch file : roslaunch < your robot_localization package path >/test/test_ekf_localization_node_bag1.test. Then subscribe to the /odometry/filtered topic and look at the last message, the position should be nearby equal to the position defined at the end of the file. Example for bag1 :Hello, i'm trying to write a launch file for robot localization package. since I don't have the sensor at hand I use a rosbag that I launch with. rosbag play --loop *****.bag.

[ERROR] [1625245130.073702909]: Client [/ekf_se] wants topic /gnss to have datatype ...For robot_pose_ekf, a common means of getting the filter to ignore measurements is to give it a massively inflated covariance, often on the order of 10^3. However, the state estimation nodes in robot_localization allow users to specify which variables from the measurement should be fused with the current state. If your sensor reports zero for a given variable and you don't want to fuse that ...

When playing data from a ROS bag file, you can use the time information from the bag to drive your system instead of your system clock ( read more here ). When the bag ends, the clock will stop, and your localization node will stop producing new estimates. This doesn't solve the issue, it will only mask it, but ...The robot_localization package is a generic state estimator based on EKF and UKF with sensor data fusion capability.

This is wokring pretty well (works perfectly with gmapping and the navigation stack). I am now in the process of adding GPS into the mix, which would allow me to do some outdoor navigation experiments. As adding GPS as sensor source is not officially supported by robot_pose ...

Detailed Description. Extended Kalman filter class. Implementation of an extended Kalman filter (EKF). This class derives from FilterBase and overrides the predict () and correct () methods in keeping with the discrete time EKF algorithm. Definition at line 53 of file ekf.h.robot_localization wiki¶. robot_localization is a collection of state estimation nodes, each of which is an implementation of a nonlinear state estimator for robots moving in 3D space. It contains two state estimation nodes, ekf_localization_node and ukf_localization_node.In addition, robot_localization provides navsat_transform_node, which aids in the integration of GPS data. ….

I would like the filtered odometry to be more dependent on the IMU and less on the GPS as the noise of the GPS is quite visible in the filtered output.
