| 20080276407 | Compact Autonomous Coverage Robot - An autonomous coverage robot includes a chassis having forward and rearward portions and a drive system carried by the chassis. The forward portion of the chassis defines a substantially rectangular shape. The robot includes a cleaning assembly mounted on the forward portion of the chassis and a bin disposed adjacent the cleaning assembly and configured to receive debris agitated by the cleaning assembly. A bin cover is pivotally attached to a lower portion of the chassis and configured to rotate between a first, closed position providing closure of an opening defined by the bin and a second, open position providing access to the bin opening. The robot includes a body attached to the chassis and a handle disposed on an upper portion of the body. A bin cover release is actuatable from substantially near the handle. | 11-13-2008 |
| 20090254218 | ROBOT CONFINEMENT - 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. | 10-08-2009 |
| 20110004339 | AUTONOMOUS COVERAGE ROBOT NAVIGATION SYSTEM - 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. | 01-06-2011 |
| 20110077802 | Robot System - 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. | 03-31-2011 |
