Unmanned aerial vehicles, better known as drones, have an image problem. Yet while privacy advocates and others criticize their use — and misuse — in military and surveillance applications, drones are also popping up in some unusual places, as new uses are discovered.

Like it or not, drones are here to stay; in 2012 the FAA estimated as many as 30,000 drones will be in use in the United States by 2020, performing tasks from border patrol to product delivery and much more. Here are just a few unique applications that drones are being considered for, or are already doing.
