Abstract
An autonomous mobile cleaning robot can include a robot body, a bumper, and a coupling. The robot body can include a displacement sensor. The bumper can be moveably coupled to the body. The coupling can include a displacement limiter associated with the displacement sensor. The displacement limiter can inhibit or limit sensing by the displacement sensor of displacement of the bumper from the robot body caused by forces below a threshold horizontal force value.
