How cmd_vel is given while using amcl?
How cmd_vel is given while using AMCL. Is there any kinematic model?. How can we add a kinematic robot model for navigation?

AMCL doesn't use command velocities, its looking for the poses from odometry in TF. Yes, AMCL has kinematic models which are described in the documentation.

The
AMCL
is used for the localization of the robot it has nothing to do withcmd_vel
. For the navigation of your robot have a look at the navigation wiki.Asked by Delb on 2019-12-04 06:14:33 UTC
