Abstract: An autonomous floor cleaning robot includes a robot body, a drive supporting the robot body to maneuver the robot across a floor surface, a pad holder attached to an underside of the robot body and configured to receive a removable cleaning pad, and a pad sensor configured to sense a pad type identifier on a central region of the cleaning pad. The pad type identifier includes a marker on the central region of the cleaning pad. The cleaning pad has a mounting card affixed thereto, and the pad type identifier includes an array of apertures that expose selected portions of the marker.

Abstract: A mobile cleaning robot can include a robot body, a bumper, and a bumper impact system. The bumper can be connected to and supported by the robot body. The bumper impact system can include a first sensor connected to the body in a first orientation with respect to the body and the bumper. The bumper impact system can include a second sensor connected to the body in a second orientation with respect to the body and the bumper different from the first orientation. The first sensor and the second sensor can together be configured to sense an impact region of the bumper based on a magnitude and a direction of movement of the bumper relative to the robot body.

Abstract: An autonomous cleaning robot includes a drive system to maneuver the autonomous cleaning robot across a floor surface; a cleaning assembly for cleaning the floor surface; and a sensor system disposed at a forward portion of the autonomous cleaning robot. The sensor system includes a movable element having (i) a first configuration in which the movable element extends beyond a bottom surface of the autonomous cleaning robot by a first amount, and (ii) a second configuration in which the movable element extends beyond the bottom surface of the autonomous cleaning robot by a second amount less than the first amount; a spring mechanically coupled to the movable element, the spring being biased to hold the movable element in the first configuration; and a sensor assembly configured to generate a signal based on the configuration of the movable element.

Abstract: A docking station for a mobile cleaning robot can include a housing. The housing can define or comprise a pad receptacle and a pad dispenser. The pad receptacle can be configured to receive a soiled pad from a pad tray of the mobile cleaning robot. The pad dispenser can be configured to provide a fresh pad to the pad tray of the mobile cleaning robot.

Abstract: A mobile robot can include a robot body; a drive system supporting the robot body above a floor surface for maneuvering the robot across the floor surface; a bumper frame on a front periphery of the robot body, the bumper frame supported by the robot body; and a bumper impact system comprising: a first sensor at a first orientation with respect to the bumper frame that is configured to generate a first signal in response to a magnitude and a direction of movement of the bumper frame relative to the robot body; a second sensor at a second orientation with respect to the bumper frame that is configured to generate a second signal in response to a magnitude and a direction of movement of the bumper frame relative to the robot body, the second orientation being different from the first orientation; and a processor.
