Abstract
An autonomous motile device (AMD) may include a light detection and ranging (LIDAR) subsystem that is usable for floor detection. The LIDAR subsystem may include a LIDAR component and a fiducial disposed in a path of light emitted by the LIDAR component. The LIDAR component provides distance data to a processor, the distance data comprising one or more distance values based at least in part on light emitted towards the fiducial. The processor determines a value based on the distance data, and determines whether the value is outside of a predetermined range of values. If the value is out of bounds, this may be indicative of the LIDAR component having malfunctioned, and the processor may cause the AMD to perform an action in response to the LIDAR malfunction.
