Drone-based surveillance still makes many people uncomfortable, but that isn't stopping research into more effective airborne watchdogs. Scientists have developed an experimental drone system that uses AI to detect violent actions in crowds. The team trained their machine learning algorithm to recognize a handful of typical violent motions (punching, kicking, shooting and stabbing) and flag them when they appear in a drone's camera view. The technology could theoretically detect a brawl that on-the-ground officers might miss, or pinpoint the source of a gunshot. As The Verge warned, the technology definitely isn't ready for real-world use.

A Florida based startup has developed a done that can carry and fire military weapons, including rifles and grenade launchers. The TIKAD drone, which was tested on a target in Israel in 2015, is remotely-operated and has been refined to absorb recoil motion from the firing of a weapon. The drone, which has the potential to reduce the number of boots on the ground in conflict situations, has already been ordered by the Israeli military and is being pitched for use by the US military. Duke Robotics co-founder and 20-year Israeli military veteran Lieutenant Colonel Raziel Atuar told Defense One that the drone can carry up to 22 pounds (10 kilograms) and is remotely operated. This means that a person would control the multirotor drone's flight and targeting from a distance.
