Ekf localization ros
robot_localization is a collection of state estimation nodes, each of which is an implementation of a nonlinear state estimator for robots moving in 3D space. It contains two state estimation nodes, ekf_localization_node and ukf_localization_node. In addition, robot_localization provides navsat_transform_node, which aids in the integration of ...imu0_relative: true. Here is the output for the /rs_t265/imu topic (mounted in front): and here is the output when using Phidgets (mounted in the back of the robot): The green odometry in the picture is the wheel odometry that is very close to the actual path traveled by the robot. The odometry marked in red is the output of robot_localization ...

The second line is just for rviz to work. I also had to add a time stamp to my simulated data: now = rospy.Time.now() imu.header.stamp.secs = now.secs. imu.header.stamp.nsecs = now.nsecs.
Any luck with multi-model landmarks fusion using ekf localization? I am trying to do a robot localization using visual landmarks that are not so robust, which means that at each observed landmark, there is a not so small probability that it could be any of two or three similar landmarks that were observed at different places in my map.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.Detailed Description.

Selected questions and answers have been migrated, and redirects have been put in place to direct users to the corresponding questions on Robotics Stack Exchange.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.
Hi, I have a pretty high quality IMU (VN-100) for which I want to test the performance with IMU-only EKF filter. I have setup my system inspired this post. However, I am experiencing the issue that the resulting /filtered/odometry shows zeros for linear displacements x,y and z.Hello, I'm already using robot_localization package ekf node.EKF fuses odometry from wheel encoders + IMU and gives a better odometry. I want to use second ekf node for getting better global localization. I just have a static map and using AMCL for global localization. For improving AMCL global localization accuracy, I have bought a GPS and want to use it to improve AMCL pose estimation.Hello, I have been trying to obtain an orientation estimate from gyroscope data using the EKF nodes. I am using a launch file (attached below) with the structure - one local EKF node in the odom frame, fusing only continuous IMU data and outputting odom->baselink TF transform, and another global EKF node in the map frame, coupled to navsat_transform_node and fusing GPS with IMU data. ….
