Abstract: A coverage robot (100) including a chassis (202), multiple drive wheel assemblies (110a-b) disposed on the chassis, and a cleaning assembly (112, 102) carried by the chassis. Each drive wheel assembly includes a drive wheel assembly housing (324a-b), a wheel (326a-b) rotatably coupled to the housing, and a wheel drive motor (328a-b) carried by the drive wheel assembly housing and operable to drive the wheel. The cleaning assembly (112, 102) includes a cleaning assembly housing (332, 338), a cleaning head (334, 340) rotatably coupled to the cleaning assembly housing, and a cleaning drive motor (336, 342) carried by cleaning assembly housing and operable to drive the cleaning head. The wheel assemblies (110a-b) and the cleaning assembly (112, 102) are each separately and independently removable from respective receptacles (304, 306, 308, 310) of the chassis as complete units.

Abstract: An autonomous mobile robot system for adjacent bounded areas (204;206) including a navigation beacon (150,202,203,304) and an autonomous coverage robot (100,212,302). The navigation beacon has a gateway beacon emitter (152) arranged to transmit a gateway marking emission (208,316) with the navigation beacon disposed within a gateway (210) between the first bounded area (204) and an adjacent second bounded area (206). The autonomous coverage robot includes a beacon emission sensor (104,106) responsive to the beacon emission, and a drive system (130,132) configured to maneuver the robot about the first bounded area (204) in a cleaning mode in which the robot is redirected in response to detecting the gateway marking emission (208,316). The drive system is also configured to maneuver the robot through the gateway (210) into the second bounded area (206) in a migration mode.
