Abstract

An autonomous mobile robot cleaner system including a robot cleaner and remote controllers for guiding the robot cleaner to rooms so as to clean several rooms in a house automatically and successively in user-selected cleaning modes. The remote controllers are placed on a corridor in the vicinity of the entrances of rooms so that a user can operate them to input information including a number assigned to each room and a cleaning mode desired for the room. The robot cleaner communicates with each of the remote controllers to obtain the information while autonomously moving around. Based on the information, the robot cleaner selects a room and a cleaning mode, enters the selected room to clean the room in the selected cleaning mode. After cleaning the room, the robot cleaner moves to the corridor and thereafter communicates with a next remote controller to repeat the above process.

Claims

1. An autonomous mobile robot cleaner system comprising:

a robot cleaner; and

remote controllers serving as signposts for guiding the robot cleaner to rooms via wireless communication,

wherein the robot cleaner includes;

a sensor for use in autonomous movement;

selection means for selecting a cleaning area from a plurality of cleaning areas and selecting a cleaning mode designated for the selected cleaning area, based on information received from each of the remote controllers via wireless communication;

moving means for autonomously moving to the cleaning area selected by the selection means and thereafter autonomously moving in the cleaning area, based on an output of the sensor;

cleaning means for cleaning the cleaning area selected by the selection means; and

communication means for wirelessly communicating with the remote controllers,

wherein each of the remote controllers includes;

setting means placed in the vicinity of an entrance of each room, which is a unit of a clearing area, so as to be operated by a user to designate a number assigned to said each room and a cleaning mode for said each room; and

communication means for wirelessly communicating with the robot cleaner in regard to information stored in the setting means.

2. The autonomous mobile robot cleaner system according to claim 1, further comprising:

means for creating map information about an already cleaned area; and

memory means for storing the map information,

wherein one of the remote controllers is placed in association with a cleaning end area for presenting cleaning end information to the robot cleaner,

wherein the robot cleaner performs a process of entering a room selected by the selection means via wireless communication with a remote controller and thereafter cleaning the room in a cleaning mode designated for the room,

wherein after cleaning the room, the robot cleaner moves out of the room and wirelessly communicates with a next remote controller to repeat the process, and

wherein when the robot cleaner wirelessly communicates with the remote controller presenting the cleaning end information, cleaning operation of the robot cleaner ends if all of the rooms are already cleaned.

3. The autonomous mobile robot cleaner system according to claim 2,

wherein the remote controllers are placed on a corridor in the vicinity of entrances of the respective rooms with the setting means allowing a user to select desired cleaning modes for the respective-rooms,

wherein the selectable cleaning modes include a normal-cleaning mode, a careful-cleaning mode to clean a room carefully, a spot-cleaning mode to clean only a central region of a room, and a no-cleaning mode to skip cleaning of a room.
