The pose is moving rapidly because your X velocity data is extremely large. This is from your odom
data, presumably from autonomy_create
.

Look at twist/twist/linear/x
. See how it's approximately 5? The units are meters per second for velocities, so the EKF thinks your robot is going at 5 m/s. I'd check the source code for the autonomy_create
package, if that's what's generating this message.
