Abstract: A multi-robot control system and method. The multi-robot control method comprises the steps in which: a central control management server configures, into multiple groups, multiple robots to perform work at a site, and designates, as a leader robot, a certain robot included in each group; the central control management server calculates a work goal of each group on the basis of the entire work; and the central control management server transmits the calculated work goal of each group to the leader robot of each group so that the leader robot of each group distributes, to robots belonging to the corresponding group, detailed missions which the robots are required to perform on the basis of the calculated work goal of each group.

Abstract: The present disclosure relates to a big data-based method or system for recommending electric vehicle (EV) charging stations with the shortest charge waiting time, which comprises a driving information receiving unit for receiving a charging station search request, and information about estimated discharge time and a current location from an electric vehicle; a charging station information receiving unit for receiving power consumption data from charging stations in real time; a charge waiting time calculation unit for receiving the power consumption data from the charging station information receiving unit, and, in response to a charging station search request, calculating charge waiting time of the charging stations on the basis of their power consumption; and an optimal charging station providing unit for receiving the information about the estimated discharge time and current location from the driving information receiving unit, and receiving the charge waiting time from the charge waiting time calculatio
