For the most part, autonomous vehicle resources can be found alongside other transportation and engineering resources, so definitely check out the other databases and books in this guide (and those for business, engineering, etc).
This page lists some resources that are aimed at the UAV/UAS industry in particular.
Other than AUVSI, these links are to commercial, ad-supported sites. AUVSI is an industry association that UND has an institutional membership to; if you would like to subscribe to them as part of the UND community, check with one of the UAV scholars on campus, the UND Innovation Center, or the aerospace librarian.
