Abstract: A backboard assembly for a vehicular rear seat is disclosed. The backboard assembly includes an upper part and a lower part, which are made of a hard plastic material. The backboard assembly prevents the formation of a gap between the lower part and a luggage board, regardless of the operational mode of the rear seat. When a seat back is folded, the upper part, the lower part, and the luggage board are aligned in a horizontal direction, thereby allowing the space for passengers in the rear seat to be completely integrated with a luggage compartment.

Abstract: A robot control system installed in a robot so as to control the robot includes a control module for controlling the robot to move along a preconfigured autonomous traveling path in an autonomous traveling mode; a mode switching module for switching the robot from the autonomous traveling mode to a movement path reconfiguration mode when predetermined switching conditions are satisfied while the robot is in the autonomous traveling mode; and a configuration module for, when the robot is moved by an external force in the movement path reconfiguration mode, tracking a movement path while the robot is moved by the external force and reconfiguring the autonomous traveling path on the basis of the tracked movement path.

Abstract: Disclosed are a multi serving robot operation method and a system therefor.
