uses odom child_frame_id to set robot_vel frame_id

If, instead, we want to take the `robot_frame_id`, we must pass the `costmap_ros_` to take it with
<pre>
costmap_ros_->getBaseFrameID();
</pre>

In that case, should I pass the `costmap_ros_` to the constructor?
Is there any plan or idea to do it?
