udacity / robot_pose_ekf Goto Github PK

Hi @karimchamaa,

It looks like you copy pasted this from the navigation stack / ros-planning work and may have accidentally illegally relicensed it under MIT.

You are more than welcome under the rights of BSD to copy paste this around as long as you retain the original copyright headers, but you may not relicense the project under MIT, which you included in the root of this package.

Also, you continue to have the license listed as BSD in the package.xml.

Given all you've done to this is add a nice README, I strongly recommend submitting a PR against the robot_pose_ekf package in ros-planning that I would merge and archiving this repository. If nothing else, please respond to change the licensing.

~$ rostopic echo /robot_pose_ekf/odom_combined

I want to echo the output of "robot_pose_ekf"

I have odom topic and topic which send robot position (only x,y). Can I use this package for fusing my data?

hi, i achieved amazing performance when run this demo project. But when i apply our own sensor data to this work, it perform not well. The odom data and vo data don't have corresponding covariance, what should i do? if the covariance is necessary, can you teach me how to figure it out? Thank you so much~

Hi, I just have a small question (I'm new to GitHub, so I'm not sure if this is the right place, but I'll give it a try). I am trying to have the "robot_pose_ekf" work with "fiducial_slam/fiducial_pose" so that a robot equipped with a camera (which would detect fiducials) would be able to determine its own position in a network of fiducials. However, when I tried running the two programs together, I got this error:

[ERROR] [1389688193.050254972]: Client [/robot_pose_ekf] wants topic /fiducial_pose to have datatype/md5sum [nav_msgs/Odometry/cd5e73d190d741a2f92e81eda573aca7], but our version has [geometry_msgs/PoseWithCovarianceStamped/953b798c0f514ff060a53a3498ce6246]. Dropping connection.

Based on what I've been looking up to fix the issue, I believe that in order to fix this I would have to alter the message type from to "geometry_msgs::PoseWithCovarianceStamped" instead of "nav_msgs::odometry":

robot.OdomCombinedSubscriber = nh.subscribe<geometry_msgs::PoseWithCovarianceStamped>("/robot_pose_ekf/odom_combined"[...]&robot);

However, when I tried looking for the abovementioned piece, I could not find it, despite looking through what seemed to be all the folders and texts. Where could I change the message type so that the error can be addressed, and if this is no longer the way to fix the error (or any other way to do so), what would that method be?

Thank you very much for your help, and I look forward to your reply! Have a great day!
