Abstract: The present invention relates to an autonomous driving cart. More particularly, the present invention relates to an autonomous driving cart that stores information on a leading subject, detects the leading subject from sensed information, and follows the detected leading subject.

Abstract: The present invention relates to an obstacle avoiding method in a state-time space, a recording medium storing a program for employing the same, and a computer program stored in a medium for employing the same. More particularly, the present invention relates to an obstacle avoiding method in a state-time space, a recording medium storing a program for employing the same, and a computer program stored in a medium for employing the same, wherein a forward trajectory is calculated on the basis of a safe timed configuration region, when collision is expected while calculating the forward trajectory, a part of the calculated forward trajectory is canceled, and a forward trajectory passing through an interim target is calculated, and thus a time required for calculating is reduced and a trajectory and success rate to the destination target state is ensured so as to obtain improvement in performance.

Abstract: A server for supporting management of a social network among users is proposed. Through execution of a server-side social network relationship management program, the server stores user personal information, and personal data registered by the users, in a database by matching with user identification information; stores group information, and group data registered by members of a group, in the database by matching with group identification information; and stores friend relationship information, and friend relationship data registered by the users establishing the friend relationship, by matching friend relationship identification information.

Abstract: The present invention relates to a cart having a leading and following function. More particularly, the present invention relates to a cart having a leading and following function and which follows a specific subject, and, when a following subject is present, decreases in velocity or stops moving, whereby the following subject can easily follow same.

Abstract: The present invention relates to an autonomous driving cart. More particularly, the present invention relates to an autonomous driving cart that stores information on a leading subject, detects the leading subject from sensed information, and follows the detected leading subject.

Abstract: The present invention relates to an online bidirectional trajectory planning method in a state-time space, a recording medium storing a program for employing the same, and a computer program stored in a medium for employing the same. More particularly, the present invention relates to an online bidirectional trajectory planning method in a state-time space, a recording medium storing a program for employing the same, and a computer program stored in a medium for employing the same, wherein autonomous driving is available while over-run or vibration does not occur in a robot by planning a bidirectional trajectory using a forward trajectory and a backward trajectory.
