Scientists from the Michigan Technological University have shown off a "drone catcher" that they hope will be used to capture rogue drones.
The "catcher" can be operated autonomously or under the control of ground based pilots. It works by launching a large net at the intended target.
Alongside this video are a few other prototypes and concepts.
