Hello ROS community, Since gmapping is a SLAM algorithm, I would like to use both the map and the localization being computed by this algorithm. From what I have seen so far, gmapping only publishes the /map and does not provide any such localization information (i.e. an estimate of the robot pose).hello, I have a nomadic scout 2-wheel robot with a kinect sensor that is able to navigate inside a map by means of the ros (groovy) navigation stack. An odometry topic is provided by the robot, and the /odom --> /base_link transform too. I want to feed the ekf_localization node with the position the robot provided by our Vicon MoCap system, in order to fuse it with the odometry information.The robot pose ekf is meant to fuse continuous sources of odometry, where the assumption of Gaussian uncertainty is reasonable. The output of amcl does not fit this description: the output pose can arbitrary 'jump' to a new location when the localization module computes a new best guess for the robot pose.Parameters¶. ekf_localization_node and ukf_localization_node share the vast majority of their parameters, as most of the parameters control how data is treated before being fused with the core filters.. The relatively large number of parameters available to the state estimation nodes make launch and configuration files the preferred method for starting any of its nodes.It's going to start out small and replace robot_pose_ekf level of functionality. The eventual difference is that it will also support global localization sensors. The best way to add GPS to these measurements is through a chain like the following: drifty GPS frame (like 'map' from amcl) -> fused odometry -> robot.# ekf_localization_node and ukf_localization_node both use a 3D omnidirectional motion model. If this parameter is If this parameter is # set to true, no 3D information will be used in your state estimate.Aug 1, 2018 · I want to implement the EKF localization with unknown correspondences (CH7.5) in the probabilistic robotics book by Thrun, to understand SLAM better.
