USE OF FIDUCIAL MARKS BY A ROBOTIC VACUUM CLEANER

Abstract: a robotic vacuum cleaner system includes a robotic vacuum cleaner comprising a camera; and a processor including: a fiducial mark detecting module; a diagnostics module; and an alert generation module. the camera is configured to obtain an image of the surroundings of the robotic vacuum cleaner, and to transmit the obtained image to the processor. the fiducial mark detecting module is configured to: receive the image of the surroundings from the camera; and detect a fiducial mark on a robotic vacuum cleaner charging station in the image. the diagnostics module is configured to determine whether the image of the fiducial mark has predetermined expected characteristics, based on the image of the fiducial mark and additional information received by the diagnostics module. if the diagnostics module determines that the image of the fiducial mark does not have the predetermined expected characteristics, the alert generation module is configured to generate an alert.
