Abstract
A method of navigating an autonomous coverage robot between bounded areas includes 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. The method also includes placing the coverage robot within the first bounded area. The robot autonomously traverses the first bounded area in a cleaning mode and upon encountering the gateway marking emission in the gateway, the robot remains in the first bounded area, thereby avoiding the robot migration into the second area. 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.
