Hardware platforms for unmanned aerial and ground vehicles are becoming increasingly commoditized, leading to low prices and high-quality equipment. This, in turn, is enabling the use of low-cost unmanned vehicles for a broadening array of civilian and commercial applications. In this paper we consider a heterogeneous group consisting of three ground vehicles and two aerial vehicles. Using this standard "team," we describe and analyze four different civilian applications to which the team is well suited, and for which existing solutions are either too costly or not effective. The applications are representative of a broad spectrum of applications in the areas of customs and border protection, infrastructure surveillance, early fire detection, and public safety incident response. For each application, we describe the overall team function, the application-specific sensor suite, the data processing and communication requirements, and any ground / operator station requirements. The focus is on solutions that require collaboration and cooperation between vehicles, and synthesis of the heterogeneous sensor data they provide.
