Publication number: 20080109126Abstract: A robot lawnmower includes a body and a drive system carried by the body and configured to maneuver the robot across a lawn. The robot also includes a grass cutter and a swath edge detector, both carried by the body. The swath edge detector is configured to detect a swath edge between cut and uncut grass while the drive system maneuvers the robot across the lawn while following a detected swath edge. The swath edge detector includes a calibrator that monitors uncut grass for calibration of the swath edge detector. In some examples, the calibrator comprises a second swath edge detector.Type: ApplicationFiled: March 19, 2007Publication date: May 8, 2008Applicant: IROBOT CORPORATIONInventors: Paul Sandin, Joseph Jones, Daniel Ozick, David Cohen, David Lewis, Clara Vu, Zivthan Dubrovsky, Joshua Preneta, Jeffrey Mammen, Duane Gilbert, Tony Campbell, John Bergman

Publication number: 20080091304Abstract: 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.Type: ApplicationFiled: June 5, 2007Publication date: April 17, 2008Applicant: iRobot CorporationInventors: Daniel Ozick, Andrea Okerholm, Jeffrey Mammen, Michael Halloran, Paul Sandin, Chik Won

Publication number: 20080039974Abstract: An autonomous coverage robot system includes an active boundary responder comprising a wire powered with a modulated current placed along a perimeter of a property, at least one passive boundary responder placed on a property interior circumscribed by the active boundary responder, and an autonomous coverage robot. The robot includes a drive system carried by a body and configured to maneuver the robot across the property interior. The robot includes a signal emitter emitting a signal, where the passive boundary responder is responsive to the signal and a boundary responder detection system carried by the body. The boundary responder detector is configured to redirect the robot both in response to the responder detection system detecting an active boundary responder and in response to detecting a passive boundary responder.Type: ApplicationFiled: March 19, 2007Publication date: February 14, 2008Applicant: iRobot CorporationInventors: Paul Sandin, Joseph Jones, Daniel Ozick, David Cohen, David Lewis, Clara Vu, Zivthan Dubrovsky, Joshua Preneta, Jeffrey Mammen, Duane Gilbert, Tony Campbell, John Bergman, Mark Chiappeita

Publication number: 20070250212Abstract: A power-saving robot system includes at least one peripheral device and a mobile robot. The peripheral device includes a controller having an active mode and a hibernation mode, and a wireless communication component capable of activation in the hibernation mode. A controller of the robot has an activating routine that communicates with and temporarily activates the peripheral device, via wireless communication, from the hibernation mode. In another aspect, a robot system includes a network data bridge and a mobile robot. The network data bridge includes a broadband network interface, a wireless command interface, and a data bridge component. The data bridge component extracts serial commands received via the broadband network interface from an internet protocol, applies a command protocol thereto, and broadcasts the serial commands via the wireless interface. The mobile robot includes a wireless command communication component that receives the serial commands transmitted from the network data bridge.Type: ApplicationFiled: December 4, 2006Publication date: October 25, 2007Inventors: Michael Halloran, Jeffrey Mammen, Tony Campbell, Jason Walker, Paul Sandin, John Billington, Daniel Ozick

Publication number: 20070244610Abstract: 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.Type: ApplicationFiled: December 4, 2006Publication date: October 18, 2007Inventors: Daniel Ozick, Andrea Okerholm, Jeffrey Mammen, Michael Halloran, Paul Sandin, Chikyung Won
