Abstract: A robotic cleaner may include a housing, a bumper, driven wheels, and a controller. The bumper can be coupled to a front of the housing. The bumper may include a plurality of projections extending from a top edge of the bumper and above a top surface of the housing. The projections may include at least one leading projection proximate a forward most portion of the bumper and at least two side projections on each respective side of the bumper. The driven wheels may be rotatably mounted to the housing. The controller may be for controlling at least the driven wheels.

Abstract: A robotic vacuum cleaner may include a housing, a displaceable bumper, an emitter/detector pair, and at least one divider. The displaceable bumper may be moveably coupled to the housing and may be configured to be displaced along at least one axis. The emitter/detector pair may have an emitter and a detector, wherein the emitter is configured to emit light through at least a portion of the displaceable bumper. The at least one divider may be disposed between the emitter and the detector of the emitter/detector pair.

Abstract: An adaptive sensor array system and method includes receiving one or more signals from a sensor array and compare the received signals to one or more object detection threshold values, determining if the robotic cleaner was moving along a travel path for a predetermined period of time, window W, in response to a determination that the robotic cleaner was operating in straight-line motion during the window W, calculating a value of the received detected signals from the sensor array during one or more calibration periods C of the window W, and adjusting one or more of the object detection threshold values based on the calculated value during the window W. A sum of all the calibration periods C during window W is less than a length of the window W. One of the calibration periods C may start at a beginning of the window W.
