Abstract: An autonomous coverage robot includes a body, a drive system disposed on the body, and a cleaning assembly disposed on the body and configured to engage a floor surface while the robot is maneuvered across the floor surface. The cleaning assembly includes a driven cleaning roller, a cleaning bin disposed on the body for receiving debris agitated by the cleaning roller, and an air mover. The cleaning bin includes a cleaning bin body having a cleaning bin entrance disposed adjacent to the cleaning roller and a roller scraper disposed on the cleaning bin body for engaging the cleaning roller. The cleaning bin body has a holding portion in pneumatic communication with the cleaning bin entrance, and the air mover is operable to move air into the cleaning bin entrance.

Abstract: A robot navigation system includes a robot, a navigation beacon, and a cover structure. The robot includes a chassis, an omni-directional receiver, and at least one directional receiver. The navigation beacon includes an omni-directional infrared emitter and at least one directional infrared emitter. The cover structure is configured to block infrared transmissions between the at least one directional infrared emitter and the directional receiver while simultaneously permitting transmissions between the omni-directional infrared emitter and the omni-directional receiver. The cover structure may be made of a black silicone material.

Abstract: An autonomous coverage robot includes a body having at least one outer wall, a drive system disposed on the body and configured to maneuver the robot over a work surface, and a cleaning assembly carried by the body. The cleaning assembly includes first and second cleaning rollers rotatably coupled to the body, a suction assembly having a channel disposed adjacent at least one of the cleaning rollers, and a container in fluid communication with the channel. The container is configured to collect debris drawn into the channel. The suction assembly is configured to draw debris removed from the work surface by at least one of the cleaning rollers into the channel, and the container has a wall common with the at least one outer wall of the body.

Abstract: An autonomous coverage robot includes a drive system, a bump sensor, and a proximity sensor. The drive system is configured to maneuver the robot according to a heading (turn) setting and a speed setting. The bump sensor is responsive to a collision of the robot with an obstacle in a forward direction. A method of navigating an autonomous coverage robot with respect to an object on a floor includes the robot autonomously traversing the floor in a cleaning mode at a full cleaning speed. Upon sensing a proximity of the object forward of the robot, the robot reduces the cleaning speed to a reduced cleaning speed while continuing towards the object until the robot detects a contact with the object. Upon sensing contact with the object, the robot turns with respect to the object and cleans next to the object, optionally substantially at the reduced cleaning speed.
