There's been a big uptick in drone research over the last decade

Recently, I was tasked with producing some basic citations on unmanned aerial vehicles, more commonly called drones, for a new grant proposal. As you could imagine, it was not hard to find a cornucopia of papers reflecting the many novel uses for the technology.

What might surprise some, though, was the sheer increase in drone research, how popular these papers are in the academic world, what that research trying to accomplish, and who was funding it.

Drones are monitoring sea mammals, keeping tabs on oil spills, helping governments prevent floods.

Every year, AUVSI, the Association for Unmanned Vehicle Systems International,hosts the biggest conference and trade show for drones in the country (but don't call them drones there; the term is UAS, for Unmanned Aerial Systems, please).

The industry group's last convention was in Las Vegas, and wrapped up earlier this month. A colleague who was there sent me the exhibition catalog. As is the custom nowadays, you could have read all that info online. But the printed version was still worth reading, and served as a snapshot of the "state of the drone."

I've taken four of what I thought were the most interesting talks, and pasted their descriptions here. The list includes researchers and developers using drones to monitor oil spills and the health of marine mammals. In one discussion, a Thai UAV company claims their technology helped the government make decisions that averted a major flood from inundating Bangkok.
