Patent number: 9038233Abstract: A floor cleaning robot comprises a housing, wheels, and a motor driving the wheels to move the robot across a floor, a control module disposed within the housing and directing movement of the robot across the floor, a sensor for detecting and communicating obstacle information to the control module so that the control module can cause the robot to react to the obstacle, a removable bin disposed at least partially within the housing and receiving particulates, a first rotating member directing particulates toward the bin, and a second rotating member cooperating with the first rotating member to direct particulates toward the bin. The removable bin receives particulates directed thereto by the first and second rotating members and the particulates pass from the first rotating member to the removable bin without passing through a filter.Type: GrantFiled: December 14, 2012Date of Patent: May 26, 2015Assignee: iRobot CorporationInventors: Joseph L Jones, Newton E Mack, David M Nugent, Paul E Sandin

Patent number: 8954192Abstract: 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: GrantFiled: June 5, 2007Date of Patent: February 10, 2015Assignee: iRobot CorporationInventors: Daniel N. Ozick, Andrea M. Okerholm, Jeffrey W. Mammen, Michael J. Halloran, Paul E. Sandin, Chikyung Won

Patent number: 8915692Abstract: An adaptable handling system featuring a boundary subsystem and one or more robots. Each robot typically includes a chassis, a container lift mechanism moveable with respect to the robot chassis for transporting at least one container, a drive subsystem for maneuvering the chassis, a boundary sensing subsystem, a container detection subsystem, and a controller. The controller is responsive to the boundary sensing subsystem and the container detection subsystem and is configured to control the drive subsystem to follow a boundary once intercepted until a container is detected and turn until another container is detected. The controller then controls the container lift mechanism to place a transported container proximate the second detected container.Type: GrantFiled: February 18, 2009Date of Patent: December 23, 2014Assignee: Harvest Automation, Inc.Inventors: Charles M.
