I'm fairly new to robotics, and I'm looking to fuse IMU, GPS, and encoder data using the ekf_localization_node. Measurements are computed by the ROS plugin, not by Gazebo. . ROS messages are objects, and the message data is stored in properties. This invokes a call to the ROS, * master node, which keeps a registry of who is publishing and who, * is subscribing.
