Abstract
Provided are an information processing device and a mobile robot capable of ensuring the accuracy of estimation of a self-position even with an environmental change and maintaining the consistency of the self-position on a map. The information processing device of the mobile robot includes a control section and a detection section configured to detect a distance to a peripheral object and the direction thereof as detection information. The control section includes a storage, a map producer configured to produce a peripheral map, an existing map self-position estimator configured to estimate a current self-position based on an existing map, a current map self-position estimator configured to estimate the current self-position based on a current map, a reliability evaluator configured to evaluate the reliability of each of the estimated self-positions, and a self-position updater configured to update either one of the self-positions based on the reliability.
