What I understand from your question is that you want to launch two instances of robot_localization for two different robots by launching then under different name_spaces. To launch the robot_localization node under a name_space you can use tag or you can pass argument __ns (args="__ns=name_space").Robot_localization with IMU and conventions. ekf_localization_node: what frame for IMU? 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 clouds

The general idea you'll want to follow w/ what you have is to use one of the 2D (or visual) SLAM algorithms to build the map and publish the map tf, and use robot_localization EKF to fuse lidar and/or visual odometry and IMU data to publish the odom tf. This together with move_base you have a pretty solid autonomous system to work with.This repository contains a ROS package for solving the mobile robot localization problem with an extended Kalman Filter. In this methodology, the Iterative …I am using ROS2 Foxy and Gazebo 11 in Ubuntu 20.04. I have a URDF description of a mobile robot that uses 4 wheels for mecanum drive.

The short answer is that the GPS coordinates get turned into a UTM pose, and that UTM pose needs to have a yaw so that we can generate a transform from the utm frame to your world frame (e.g., map).Forgetting GPS positions for a moment, the UTM grid is a world-fixed coordinate frame, just like map or odom in the EKF. If you want to transform coordinates from one frame into ...Original comments.

Hi. I am using ekf_localization_node for fusing imu, wheel odometry and amcl_pose ( My config is as follow ) The reason why i am using amcl_pose; When i use odom0_differential: true the filter output odometry_filtered/odom covariance grows quickly. It doesn't grow with adding amcl_pose. Aynway the main problem is everything is working fine for a few hours (in my case 5 hours) then the output ...If the former, the second (map) robot_localization node never publishes anything if I fuse the output of the first directly.

The result from topic /odometry/filtered looks even worst than the only wheel odometry result.

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.

Then robot_localization can help fuse the estimate of the scan-to-map matcher with your odometry using an EKF. But I am afraid I don't know about individual ROS packages providing a scan-to-map matching feature in isolation, you would have to look at how it is implemented in the various localization/SLAM packages out there. I'm starting to use ...

This repository include an example application of Extended Kalman Filter using robot_pose_ekf ROS package on gazebo turtle bot simulation package using its IMU and wheel odometry data. Directory StructureThat means the EKF is going to ignore it completely. You have two_d_mode set to false, which means you want a full 3D state estimate, but you are only fusing 2D variables. Unmeasured variables in the EKF will result in absolute explosions of those variables' covariance values, which will have irritating effects on other variables.Let’s begin by installing the robot_localization package.
