Missed target, found hooliganism on drone mapping mission

A small unmanned aircraft system for mapping, developed for a National Science Foundation grant to improve STEM education.

In north Louisiana, there’s a fantastic little place known for Muscadine grapes, pecans, and on occasion, alligators.

Muscadines always get turned into jelly; an excellent topping for southern-style biscuits (my wife says she’s still working on mastering the family biscuit recipe, but she’s produced the finest biscuits I’ve ever had the pleasure of eating).

Pecans, a grocery bag of which could fetch a gold bar by northern exchange rates, are so plentiful that they must be given away. They’re so much a part of my wife’s heritage that we decided to get married beneath those pecan trees.

And when the water is high in the backyard bayou, a small alligator sometimes will make itself at home. If the alligator is lovingly cared for and becomes fat, a portion of that alligator eventually will make its way to our dinner table in the form of a delightful alligator sauce piquant (wife insists that it be cooked like shrimp, and not burnt to a crisp as it’s done here in the North).

So before we went down to visit my wife’s family farm for Thanksgiving, I decided to pack up one of the “drones” I’ve developed at the National Science Foundation grant where I work, to see if I couldn’t map out this interesting place.

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.

Building and flying an incredibly tiny quadrotor drone

At the National Science Foundation grant where I work, EnLiST, we've been tinkering with various different drone platforms which could be easily deployed in classrooms for valuable STEM (Science Technology Engineering and Mathematics) lessons.

Although we're focused on STEM education, it's not hard to see how some of these drones can be used in a variety of other fields. The quadrotors we develop one day could be deployed for research in environmental science, geology, city planning, and even "evidence-based" journalism.

Drones are useful like that. At the end of they day, they're simply a means of getting a sensor from one place to another. What you use that sensor for, is entirely up to the teacher, scientist, or journalist.

We needed a drone that was small enough to fly in a classroom, easy enough for children to fly (not saying much as kids tend to pilot drones with relative ease), and hackable enough that we could mold it to fit our science curriculum.

Enter the Crazyflie nano, a tiny, open-source drone developed by Swedish hackers at Bitcraze.se. At 19 grams, and measuring 9 cm from motor to motor, it's one of the smallest quadrotor drones on the market today.
