I am looking at robot_pose_ekf to combine multiple odometry sources into a more robust odometry estimate for our robot. It looks like the package combines wheel, visual and imu odometry information, but it does not take into account the velocity commands sent to the robot when updating the filter ... it instead just updates with the Gaussian system model. Just checking to make sure this is indeed the case, and there's no other way the robot commands get in there. The plots on the wiki look like this implementation is working quite well ... are commands just not used because the system works well enough? I suspect for our robot we'll need the additional information in the filter.
