Abstract
The present invention relates to a mobile robot for evaluating self-training based traversability comprising: an elevation map generator which generates a grid-cell based elevation map using point cloud data; a feature extractor which extracts a plurality of types of features on each grid cell from the elevation map; a data set generator which generates a labeled data set labeled for training and an unlabeled data set, based on label features set for at least two types of features among the plurality of types of features; and a self-training unit which generates an AI model for evaluating traversability by self-training using the labeled data set and the unlabeled data set. Accordingly, it is possible to create training data which increases training ability and then use the data for the self-training, whereby traversability can be evaluated while achieving navigation safety and efficiency.
