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.

Abstract: An example robot includes a body that is movable relative to a surface, a bumper mounted on the body to enable movement of the bumper relative to the body, a sensor to produce a signal in response to the movement of the bumper relative to the body caused by contact between the bumper and the surface, and a controller to control movement of the body to cause the body to track the surface based on a value. The bumper is movable between an uncompressed position relative to the body and a compressed position relative to the body. The signal varies linearly with the movement of the bumper relative to the body. The value is based on the signal and indicates that the bumper in a partially compressed position has a compression range between the uncompressed position and the compressed position.

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: 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 method of operating an autonomous cleaning robot includes presenting, on a display of a mobile device, a representation of each of multiple cleaning levels, each cleaning level corresponding to a respective rank overlap parameter for a wet cleaning mission of the autonomous cleaning robot. The method includes receiving, at the mobile device, an input indicative of a selection of one of the cleaning levels; and controlling the autonomous cleaning robot to execute a wet cleaning mission according to the rank overlap parameter corresponding to the selected one of the cleaning levels.

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.
