1. An automated asset management system comprising: a plurality of storage locations for storing objects; first and second sensing subsystems each configured to sense presence or absence of the objects in the plurality of storage locations of the asset management system, wherein the first and second sensing subsystems are configured to sense the presence or absence of a same particular object in the asset management system using different respective first and second sensing modalities; a processor; and a non-transitory machine readable recording medium storing program instructions which, when executed by the processor, cause the processor to: perform a scan of the storage locations using the first sensing subsystem, and determine the presence or absence of the particular object in the plurality of storage locations using the first sensing modality of the first sensing subsystem, perform a scan of the storage locations using the second sensing subsystem, and confirm the presence or absence of the particular object in the plurality of storage locations using both the result of the determination made using the first sensing modality and a determination of the presence or absence of the particular object using the second sensing modality of the second sending subsystem.
