  • Publication number: 20190246862
    Abstract: A surface treatment robot includes a chassis having forward and rear ends and a drive system carried by the chassis. The drive system includes right and left driven wheels and is configured to maneuver the robot over a cleaning surface. The robot includes a vacuum assembly, a collection volume, a supply volume, an applicator, and a wetting element, each carried by the chassis. The wetting element engages the cleaning surface to distribute a cleaning liquid applied to the surface by the applicator. The wetting element distributes the cleaning liquid along at least a portion of the cleaning surface when the robot is driven in a forward direction. The wetting element is arranged substantially forward of a transverse axis defined by the right and left driven wheels, and the wetting element slidably supports at least about ten percent of the mass of the robot above the cleaning surface.

  • Publication number: 20180116479
    Abstract: An autonomous coverage robot detection system includes an emitter configured to emit a directed beam, a detector configured to detect the directed beam and a controller configured to direct the robot in response to a signal detected by the detector. In some examples, the detection system detects a stasis condition of the robot. In some examples, the detection system detects a wall and can follow the wall in response to the detected signal.

  • Publication number: 20160075024
    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. In some example, the navigation beacon may also transmit a proximity emission laterally about the beacon, where the robot avoids cleaning and migration within the proximity emission. 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.

  • Patent number: 9144360
    Abstract: 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.

  • Patent number: 8606401
    Abstract: A navigation beacon controls movement of a mobile robot in first and second areas. The navigation beacon includes a portable housing, a power source, and an emitter. The emitter is operable to emit a gateway marking emission when the robot is within a field of detection that extends between the areas. The gateway marking emission is detectable by the robot and prevents the robot from moving from one of the areas, through the field of detection, to the other of the areas. A switch is operable to switch the navigation beacon to be in an OFF mode in which the gateway beacon emitter is in an OFF state, a confinement mode in which the gateway beacon emitter is in an ON state, and a navigation mode in which the gateway beacon emitter is in the ON state and automatically switches to the OFF state in response to a predetermined condition.
