    Abstract: An autonomous floor cleaning robot includes a robot body defining a forward drive direction, a controller supported by the robot body, a drive supporting the robot body and configured to maneuver the robot across a surface in response to commands from the controller, a pad holder disposed on an underside of the robot body and configured to retain a removable cleaning pad during operation of the cleaning robot; and a pad sensor arranged to sense a feature of a cleaning pad held by the pad holder and generate a corresponding signal. The controller is responsive to the signal generated by the pad sensor, and configured to control the robot according to a cleaning mode selected from a set of multiple robot cleaning modes as a function of the signal generated by the pad sensor.

    Abstract: An autonomous floor cleaning robot includes a body, a controller supported by the body, a drive supporting the body to maneuver the robot across a floor surface in response to commands from the controller, and a pad holder attached to an underside of the body to hold a removable cleaning pad during operation of the robot. The pad includes a mounting plate and a mounting surface. The mounting plate is attached to the mounting surface. The robot includes a pad sensor to sense a feature on the pad and to generate a signal based on the feature, which is defined in part by a cutout on the card backing. The mounting plate enables the pad sensor to detect the feature. The controller is responsive to the signal to perform operations including selecting a cleaning mode based on the signal, and controlling the robot according to a selected cleaning mode.

    Abstract: A robot includes a body that is movable relative to a surface one or more measurement devices within the body to output information based on an orientation of the body at an initial location on the surface, and a controller within the body to determine an orientation of the body based on the information and to restrict movement of the body to an area by preventing movement of the body beyond a barrier that is based on the orientation of the body and the initial location.

    Abstract: A cleaning pad for an autonomous cleaning robot evenly wets and collects debris for cleaning operations. The pad includes a core of absorbent layers for absorbing liquid through capillary action and for distributing the liquid within the cleaning pad. The pad includes a wrap layer around the core, the wrap layer comprising a fibrous layer that is flexible and absorbent, the fibrous layer configured to absorb liquid through capillary action and transfer the liquid to the core. The pad includes one or more transition regions spanning a cleaning width of the cleaning pad, the one or more transition regions dividing the cleaning pad into at least two segments. The forward positioned segment of the pad, of the at least two segments of the pad, has a lesser thickness compared to a thickness of an aft positioned segment of the at least two segments.
