Many asymptotic covariance estimates are generated using uncontaminated model distributions and thus are often based in part on the information matrix. Such covarianee estimators have a low breakdown point (Donoho and Huber, 1983;Huber, 1981; Hampel et al., 1986, p. 98;Lopuhaa and Rousseeuw, 1991),

We have previously presented a new scan-matching algorithm based on the IDC (iterative dual correspondence) algorithm, which showed a good localization performance even in environments with severe changes. The problem of the IDC algorithm is that there is no good way to estimate a covariance matrix
