# Description

in `NonHolonomicAction.apply_actions()` the velocity command was
incorrectly named `self.joint_vel` instead of `self._joint_vel_command`
as initialized in `NonHolonomicAction.__init__()`. This causes an error
when trying to instantiate the action config. I have corrected
and tested that it works.
