Mo Rastgaar, an associate professor of mechanical engineering at Michigan Technological University, and his team have developed a drone catcher that can pursue and capture rogue drones that might threaten military installations, air traffic, sporting events, and even the White House — as startled Secret Service officers discovered when one crash-landed on the White House lawn last January.
Other potential applications include foiling spy drones, smugglers, and terrorists, and supporting the recent FAA announcement requiring drones to be registered.
