 * Option _"-s robot"_ is meant to be used if the corrected pose from AICP is fed back into the state estimator. Each corrected pose is published only once as soon as computed.
 * Option _"-s debug"_ is meant to be used during debug. The corrected pose message is published at the same frequency as the pose estimate from the state estimator \(for visualization purposes\).
