1. A method of navigating an autonomous coverage robot between bounded areas, the method comprising:

  • positioning a navigation beacon in a gateway between adjoining first and second bounded areas, the beacon configured to transmit a gateway marking emission across the gateway; and

    placing the coverage robot within the first bounded area, the robot autonomously traversing the first bounded area in a cleaning mode and, upon encountering the gateway marking emission in the gateway, remaining in the first bounded area, thereby avoiding robot migration into the second area;

    wherein upon termination of the cleaning mode in the first area, the robot autonomously initiates a migration mode to move through the gateway, past the beacon, into the second bounded area.
