Michigan Tech Drone Catcher Acts Like Robotic Falcon
Last January, a Washington, D.C., hobbyist accidentally flew his DJI Phantom quadcopter drone over the White House fence and crashed it onto the lawn. Two years earlier, a prankster sent his drone toward German Prime Minister Angela Merkel during a campaign rally.
Small drones have also proven to be effective tools of mischief that doesn’t make the national news, from spying to smuggling to hacking.
So when Mo Rastgaar (MEEM) was watching World Cup soccer and heard about snipers protecting the crowd, he doubted that they’d fully understood a drone’s potential.
“I thought, ‘If the threat is a drone, you really don’t want to shoot it down—it might contain explosives and blow up. What you want to do is catch it and get it out of there.’”
Rastgaar, an associate professor of mechanical engineering at Michigan Tech, began work on a drone catcher, which could pursue and capture rogue drones that might threaten military installations, air traffic, sporting events—even the White House.
It’s a deceptively simple system: a launcher that shoots a big net attached to a large drone by a string. The system can be autonomous, controlled by a ground-based human pilot or a combination of the two.
After an intruding drone is spotted, the drone catcher takes up the chase and fires the net at it from a distance of up to 40 feet. Because the net is so big and can be deployed so quickly, it can overwhelm even the fastest, most maneuverable small drone. Read the full story.
