1. A method for detecting and identifying threats during a structure clearing or inspection operation performed with an autonomous remote vehicle, the method comprising: mounting a self-contained threat detection sensor suite payload on the remote vehicle, the threat detection sensor suite comprising a processor configured to run executable software for performing autonomous and semi-autonomous behaviors for the structure clearing or inspection operation; detecting a target; identifying that the target is of interest; moving toward the target until any legible markings can be determined; determining legible markings, wherein determining legible markings is accomplished by optical character recognition; moving close enough to the target that one or more environmental sensors can sense environmental characteristics of the target; gathering environmental characteristic data with the one or more environmental sensors; and combining and analyzing data gathered to identify the target.
