The reusable anti-aircraft device DroneBullet was developed by Canadian startup AerialX. DroneBullet is a drone, but it is primarily focused on destroying other drones instead of just making long flights. The device is extremely durable, which allows it to disarm other drones with ram-attacks.
DroneBullet is equipped with a complex system of motors and propellers that allow it to make incredible manoeuvres in the air and make a soft landing back to its base. The device can endure even heavy impact which makes it possible to reuse multiple times.
DroneBullet uses machine vision to easily identify targets, chase them down and disarm them. The gadget is extremely fast, so running away from it would be quite challenging.
