Reconfigurable unmanned aerial vehicles. [PDF]
, 2009 Unmanned Aerial Vehicles (UAVs) have been developing dramatically due to wars and miniaturisation of technology, which has made the UAV industry a very lucrative business. Research organisations have been funded by various research committees or military groups to push UAV developments at a very fast pace.

Mapping <i>Lupinus polyphyllus</i> density and distribution along road verges using unmanned aerial vehicle (UAV)-based remote sensing. [PDF]
Appl Plant SciAbstract Premise Road verges function as refuges for semi‐natural species, but they can also facilitate the spread of non‐native plants such as Lupinus polyphyllus. Unmanned aerial vehicle (UAV)–based remote sensing is a promising tool for mapping these species; however, its application in roadside contexts remains limited.
