SPIDER-MAN DRONE CATCHES OTHER DRONES JUST LIKE FLIES:

Mo Rastgaar, an associate professor of mechanical engineering at Michigan Technological University (MTU). Rastgaar and his team have developed a drone that has the ability to shoot a large net at another drone from as far as 40 feet (12 meters) away, then bag it up and carry it away. The net-shooting drone can function autonomously or be controlled by a human operator.
