The EKF and UKF in robot_localization do support pose messages; they need to be of type sensor_msgs/PoseWithCovarianceStamped. A `sensor_msgs/PoseStamped' message does not contain covariance information, which is required by Kalman filters. Without it, the filter doesn't know how much to trust its own prediction vs. the measurements provided.
