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.
