Patent number: 8271129Abstract: 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: GrantFiled: December 4, 2006Date of Patent: September 18, 2012Assignee: iRobot CorporationInventors: Michael J.

Publication number: 20110004339Abstract: 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.Type: ApplicationFiled: July 1, 2010Publication date: January 6, 2011Applicant: IROBOT CORPORATIONInventors: Daniel N.

Publication number: 20090254218Abstract: A robot lawmnower includes a body, a drive system carried by the body, at least one caster wheel supporting the body, a grass cutter carried by the body, a controller in communication with the drive system, and a bump sensor in communication with the controller. The controller is configured to maneuver the robot to turn in place and to redirect the robot in response to the bump sensor sensing contact with an obstacle. The drive system is configured to maneuver the robot across a lawn and includes differentially driven right and left drive wheels positioned rearward of a transverse center axis defined by the body. The at least one caster wheel is positioned substantially forward of the right and left drive wheels, and the grass cutter is positioned at least partially forward of the right and left drive wheels and at least partially behind the at least one caster wheel.Type: ApplicationFiled: June 19, 2009Publication date: October 8, 2009Inventors: PAUL E.

Publication number: 20090228165Abstract: 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 23, 2008Publication date: September 10, 2009Inventors: Daniel N.

Publication number: 20040047367Abstract: One aspect of the present invention provides a method and an apparatus for setting the size of a variable buffer. The method in one embodiment includes setting the initial size of the buffer to zero, reading messages into and out of the buffer, and increasing the average depth of the variable buffer, if underflow occurs. In another embodiment, the method includes repeatedly reading messages and increasing the average depth of the buffer if underflow occurs, until the average depth of the buffer converges to a point to produce a substantially low delay in message transmissions while substantially reducing the possibility of future underflows due to packet delay variation.Type: ApplicationFiled: September 5, 2002Publication date: March 11, 2004Applicant: LITCHFIELD COMMUNICATIONS, INC.Inventor: Jeffrey W.

Patent number: 5978741Abstract: Line voltage and line current signals are sensed on a power line having at least one conducting path. The sensed line voltages and line currents are converted into a digital signal. A phase-to-neutral voltage signal and phase current signal are computed from the digital signal to thereby define a phase of the power line. An interval of orthogonality is determined from the sensed voltage and current signals, coinciding with passage of an integral number of cycles of a fundamental frequency reference signal which is computed from the computed phase-to-neutral voltage signal. A vector metering quantity is computed for the determined interval of orthogonality from the computed phase-to-neutral voltage signal and the computed phase current signal. The vector metering quantities to be computed may be identified and computed based upon an associated detent. The vector metering quantity is also computed based on an identified circuit topology.Type: GrantFiled: April 9, 1997Date of Patent: November 2, 1999Inventors: David D. Elmore, Daniel A.
