An autonomous mobile robot system for bounded areas including a navigation beacon and an autonomous coverage robot. The navigation beacon has a gateway beacon emitter arranged to transmit a gateway marking emission with the navigation beacon disposed within a gateway between the first bounded area and an adjacent second bounded area. The autonomous coverage robot includes a beacon emission sensor responsive to the beacon emission, and a drive system configured to maneuver the robot about the first bounded area in a cleaning mode in which the robot is redirected in response to detecting the gateway marking emission. The drive system is also configured to maneuver the robot through the gateway into the second bounded area in a migration mode.
1. A cleaning system for cleaning a room, the cleaning system comprising: an autonomous mobile robot comprising: a chassis;drive wheels connected to the chassis for moving the mobile robot to a docked position;a central receiver and two side receivers located at a front portion of the chassis; anda
1. A cleaning system for cleaning a room, the cleaning system comprising: an autonomous mobile robot comprising: a chassis;drive wheels connected to the chassis for moving the mobile robot to a docked position;a central receiver and two side receivers located at a front portion of the chassis; anda controller located within the chassis and configured to receive signals from at least two of the receivers and direct the mobile robot toward a docked position using the receiver signals; anda base station comprising three infrared emitters, the three infrared emitters comprising at least two side emitters spaced in opposite directions from a central location of the base station, at least two of the emitters being detectable by the mobile robot from a position proximate the base station when the mobile robot is aligning itself for docking,wherein the receivers of the mobile robot are configured to receive infrared directed beams from at least the two side emitters of the base station, and the controller of the mobile robot is configured to direct the mobile robot toward a docked position on the based station using the infrared directed beams received from the two side emitters when the robot is in a docking mode, the controller including a control routine for docking the mobile robot from a position within the room wherein the mobile robot has been aligned for docking but is outside of a range of an infrared directed beam that maintains contact with the mobile robot until the mobile robot is docked. 2. The system of claim 1, wherein the controller can differentiate one infrared directed beam from the other infrared directed beam. 3. The system of claim 2, wherein the beams are differentiated by time division multiplexing with a fixed period random offset. 4. The system of claim 2, wherein the beams are differentiated by encoding of the beams. 5. The system of claim 4, wherein the beams are encoded by modulation with differing serial codes. 6. The system of claim 2, wherein the side emitters are arranged on the base station to emit laterally bounded and overlapping fields of emissions of signal beams. 7. The system of claim 2, wherein each of the side emitters projects a beam of about twelve degrees from a direction normal to the emitter. 8. The system of claim 2, wherein the side emitters are positioned such that their angle of overlap is between about six degrees and about ten degrees, and each emitter's aperture angle is about twenty to about thirty degrees. 9. A method for navigating a mobile cleaning robot to a docked position on a base station having three emitters, at least two of the base station emitters being side emitters spaced in opposite directions from a central location of the base station, the method comprising: receiving infrared directed beams from the side emitters when the robot is in a docking mode and until the robot is docked, the infrared directed beams being indicative of a docked position; anddriving the mobile robot to the docked position on the base station using the infrared directed beams by aligning the robot for docking when the robot is within range of all three emitters. 10. The method of claim 9, further comprising charging a power source of the mobile robot when the mobile cleaning robot is in a docked position. 11. The method of claim 9, further comprising differentiating one infrared directed beam from the other infrared directed beam. 12. The method of claim 11, further comprising differentiating the infrared directed beams by time division multiplexing with a fixed period random offset. 13. The method of claim 11, further comprising differentiating the infrared directed beams by encoding the beams. 14. The method of claim 9, further comprising identifying each infrared directed beam by its modulation. 15. The method of claim 9, wherein receiving infrared directed beams from the side emitters comprises receiving infrared directed beams within a sweep angle of between about twenty eight degrees and about thirty three degrees.
