Integrating GPS Data ¶. Integration of GPS data is a common request from users. robot_localization contains a node, navsat_transform_node, that transforms GPS data into a frame that is consistent with your robot’s starting pose (position and orientation) in its world frame. This greatly simplifies fusion of GPS data.可以融合任意数量的传感器。EKF节点不限制传感器的数量,如果机器人有多个 IMU 或多个里程计,则 robot_localization 中的状态估计节点可以将所有的传感器的数据进行融合。 支持多种 ROS 消息类型。

I use a simulated turtlebot 3 which is in the /robot1/ namespace and has robot1_tf as tf-prefix. I use a robot_localization ekf for the robot1_tf/odom frame and a separate one for the map. The problem here is that this map ekf always uses robot1_tf/map as map frame. But I need map as map-frame.The aruco_localization node publishes two topics: estimate and measurements.Given an ArUco marker dictionary, any markers in that dictionary family will be identified and the measurement to that specific marker will be reported in the measurements topic. The estimate topic provides the overall pose estimate of a marker map. The marker map that is being tracked is defined in the markermap ...I have an arg named husky_ns defined in my launch file. I have set it to husky_1.. Using the ekf_localization_node (from the robot_localization package), I want to publish the husky_1/odom to /husky_1/base_link transform on the tf tree.

Hello, I am fusing odometry from a lidar (I have it thanks to undocumented pub_odometry parameter of hector_slam), IMU and GPS data. I am using the dual_ekf_navsat_example. My odom message has no twist information, only pose. So that it is taken into account by ekf_se_odom, I need to publish it with frame_id = odom, because world_map of ekf_se_odom is odom.ekf_localization_node and ukf_localization_node use a combination of the current ROS time for the node and the message timestamps to determine how far ahead to project the state estimate in time. It is therefore critically important (for distributed systems) that the clocks are synchronized.

We're running a robot with two ekf, the first ekf processes IMU and Odometry, and the second one process the output of the first ekf and adds the filtred gps from the navsat_transform node. However, when running the setup on ROS dist Melodic we got the following error: [ERROR] [1613489401.836650482, 25.942000000]: Global Frame: odom Plan Frame size 2: map [ WARN] [1613489401.836680933, 25. ...Hello there!
