Hello there, I am attempting the obtain accurate pose information from my "global ekf" (with map -> odom transform) in the event that my lidar stops functioning, which results in AMCL to stop publishing pose updates. To give some context, I have two r_l nodes running. The first in "local mode" (odom -> base_link) and the second in "global mode" (map -> odom).

Apr 3, 2017 · To initialize the EKF to a location, I use the /set_pose rosservice call, which works IF odom0_differential=true. /set_pose does not work if odom0_differential=false. There is a tiny blip on the EKF output to the set location, but then the EKF starts at 0 again.So I'm using Dr Robot's Jaguar 4x4 robot on Ubuntu 16.04 and Ros Kinetic. I want to use the robot for autonomous navigation. I'm currently using robot_localization package of ROS for localization. But I've encountered into a problem.

If you want to transform it, you'll need to write a node that takes in the quaternion and converts it. Alternatively, you can use tf_echo to listen to the world_frame->base_link_frame transform being broadcast by ekf_localization_node. tf_echo does the conversion for you.

Hello dear ROS community. I'm trying to use robot_localization with the ekf node inorder to produce an accurate orientation of my robot using 3 IMUs. I wrote the program for the IMU (Sparkfun SEN-14001) myself and it works pretty good. The IMUs give euler angles with respect to a fixed world frame which is exactly what i need.

(package summary - documentation) Each of the state estimators can fuse an arbitrary number of sensors (IMUs, odometers, indoor localization systems, GPS receivers…) to track the 15 dimensional (x, y, z, roll, pitch, yaw, x ...All pose data for the EKF needs to either be in the world frame (e.g., odom ), or needs to have a transform _to_ that world frame. The rule basically comes down to this: don't fuse pose data that comes from a frame_id that is a child of the base_link_frame.

You're not the first person to want that kind of functionality in a node, so if there are no others, you might consider writing one and releasing it. Note, however, that some GPS devices provide heading based on differentiated positions, and their ROS drivers would likely fill out those fields in the messages they produce.EKF kicks off, gets a single IMU measurement from, e.g., imu3. So its first output has a pose and position of 0, with whatever angular velocity was in that message. navsat_transform_node is ready, and gets all its input data, including that first pose from the EKF (i.e., input 3 above). That pose is 0. EKF fuses pose from some other source.

I have been using this package for localization and noticed the (x, y) position estimate jumping sometimes, seemingly randomly. I enabled the debug logs and have narrowed it down to certain pose measurement correction steps.

But, I guess, both is impossible with the current version of robot_localization. Sure, since there is no absolute information for a period of time, the EKF pose uncertainty grows unboundedly.Hi, I I'm trying both packages and I think I'm going to use robot_pose_ekf instead as it just takes in euler angles as input for imu.
