Abstract: An attribute about person's mobility capability is judged by a human movement attribute acquisition unit. Candidate paths for a detected person to move along are created by a human path candidate creation unit based on information about the person and a predicted time left for a collision between the autonomous locomotion apparatus and the person. A movement load for each candidate path is evaluated by a human path load evaluation unit based on an attribute of person's movement. A path which imposes a minimum movement load on the person, i.e., a path suitable for the person's mobility capability and the easiest for the person to avoid the autonomous locomotion apparatus is selected by a human path determination unit. A path for the autonomous locomotion apparatus to guide the person to the selected path is planned by a guide path planning unit.

When there is probability of contact between the detected person and the autonomous locomotion apparatus based on movement information of the person, the autonomous locomotion apparatus controls a traveling speed or a rotational speed of the autonomous locomotion apparatus to perform a guide operation which presents a path of the autonomous locomotion apparatus which is intended to cause the person to predict, so that it causes the person to avoid the path without giving the person a sense of uneasiness.
