Title: Guidance robot and method for navigation service using the same
Inventor: HUH JI YOUNG
IPC: B25J13/00
Filed: 2019-08-22
Abstract: The present invention relates to a facility guidance robot for guiding a visitor of a facility. The facility guidance robot includes a robot body, a driving unit, a reception unit, a memory, and a processor. According to the present invention, a moving space in which a moving robot drives can be divided so that the moving robot capable of driving drives. Also, a sensed object can be excluded in case that the object around the moving robot, which is sensed by the moving robot, corresponds to learning information on an obstacle mechanically learned by the moving robot. In other words, a map in which the moving robot moves is divided into multiple moving areas. So, when the moving robot completes the driving in one space, the moving robot starts to drive in the other space but not driving by moving in multiple spaces. So, the facility guidance robot can prevent driving efficiency of the moving robot from deteriorating. Also, the moving robot can suck foreign substances around the moving robot while driving. In case that the object which the moving robot senses while driving has a predetermined weight or greater and a predetermined size or greater, the object is excluded from the map in which the moving robot moves. So, the facility guidance robot can prevent interference with the object which cannot move while moving robot drives.
