def delete_from_ros(self, service_name='rigid_transforms/rigid_transform_publisher', namespace=None):
        """Removes RigidTransform referencing from_frame and to_frame from ROS publisher.
        Note that this may not be this exact transform, but may that references the same frames (order doesn't matter)

        Also, note that it may take quite a while for the transform to disappear from rigid_transform_publisher's cache 

        Requires ROS rigid_transform_publisher service to be running. Assuming autolab_core is installed as a catkin package,
        this can be done with: roslaunch autolab_core rigid_transforms.launch

        Parameters
        ----------
        service_name : string, optional
            RigidTransformPublisher service to interface with. If the RigidTransformPublisher services are started through
            rigid_transforms.launch it will be called rigid_transform_publisher
        namespace : string, optional
            Namespace to prepend to transform_listener_service. If None, current namespace is prepended.

        Raises
        ------
        rospy.ServiceException
            If service call to rigid_transform_publisher fails
