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: A robotic cleaner may include a body, an optical receiver, the optical receiver being configured to detect an optical signal generated by an external device, and an optical pattern generator configured to emit light according to an optical pattern that extends at least partially around the body, wherein, when the optical pattern intersects an obstacle, at least a portion of the light incident on the obstacle is reflected towards the optical receiver, the optical receiver being configured to detect the reflected light.

Abstract: A robotic cleaner may include a body and an illuminator assembly. At least a portion of the illuminator assembly may be disposed within the body. The illuminator assembly may include an illuminator optic configured to emit light from an illumination surface and an illumination guide configured to direct light into the illuminator optic. The illumination guide may have a cavity. The cavity may include a reflecting surface and a directing surface, the reflecting surface being positioned opposite the directing surface.
