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: 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 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.
