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.In this paper, it corresponds to the robot type (3,0), but the model in robot_localization is in 3D. Each variable has a nonlinear transition function, and we encode those transition functions as a matrix. So, for example, the transition function for x is x_new = x_old + vx * t + 0.5 * a * t^2, but v and a are given in the body frame of the ...

All of the sensor measurements are incorporated as measurement updates in the EKF. So, if you were to look at the r_l code responsible for the prediction step of the EKF here (specifically if you look at the transfer functions defined), you'll see that state prediction is entirely based on the current estimate.74 240 232. Both ekf_localization_node and ukf_localization_node assume that all measurements provide either the robot's body frame (base_link) velocity, its world frame (map or odom) pose, or its body frame linear acceleration. Of course, if your data is provided in another coordinate frame, that's fine, so long as a transform exists between ...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. This tutorial explains how to use …Extended Kalman Filter: Incorporating GPS Using robot_pose_ekf. As a field robotics company, Clearpath Robotics loves using GPS systems! However, ROS does not yet provide an effective method of incorporating GPS measurements into robots. A natural place to start incorporating GPS is in the navigation stack, specifically robot_pose_ekf.
