Technology is constantly expanding, and this is particularly true when it comes to unmanned aerial vehicles. Drones are quickly gaining popularity with the military, government institutions and in the civilian sector and uses for UAVs are expected to expand dramatically in the years to come - so much so that the Federal Aviation Administration (FAA) has been charged with developing new rules governing their deployment.

In fact, UAV technology has now progressed to the point where they can be controlled by thought. Per tech website PopSci:

Researchers at the University of Minnesota [have] revealed a drone that can be controlled merely by thought, and that's not even the coolest thing about it. Published in the Journal of Neuro Engineering, the project has implications in everything from unmanned vehicles to paraplegic mobility.

According to researchers, the futuristic capabilities are actually very basic. The drone itself is now commercially available as a four-blade helicopter called the Parrot AR quadrotor, which is essentially a drone hobbyist's Model T (the first mass-produced automobile).

A funny hat and a laptop

"To control it, the 'pilot' wears a funny hat, the sensing end of an electroencephalogram (EEG)," PopSci reported. "EEGs place an array of electrodes over a person's head, in a totally non-invasive way, then pick up on electrical activity in the brain. Clusters of activity, like thinking about making a fist with a right hand, generates a spark in a specific area of the brain. That spark gets translated through a computer into a quadrotor command ('turn right'). The command is then beamed to the quadrotor via WiFi."
