Engineering360: "Army to test grenade-launching drone"

...and, thus, began the 'Skynet' weapon systems...next, comes the 'satellites.'

I don't believe that it is autonomous. It may have certain autonomous navigation features such as return to launch site, but the deployment of weapons certainly has human input. Fire and forget weapons have been around for decades, but a human has to decide to initiate the firing at the intended target.

So, when something goes 'wrong', will things turn into "Red Screens" instead of "Blue Screens"?

The concept of a drone armed with a shotgun should be brought to the attention of state legislators. A bird hunter using one of these probably has an unfair advantage over other hunters; it's about as sporting as shooting birds on the water (which is generally illegal). There may be a serious safety hazard to people on the ground, since the pellets will have a greater descending velocity if fired at a horizontal angle or below, and drone operators may not always accurately predict the ground impact point of pellets that do not hit the target. At a minimum, the legislatures should call for tests to see if these concerns are justified.

Where was that mentioned in this article?

It wasn't mentioned in the article, but if the idea of adapting a drone to fire a shotgun shell is out there, somebody might get the bright idea of trying it against game birds in flight. That's why legislatures should figure out whether that's going to be a problem, and consider whether to regulate or ban the practice.

In some circumstances, it may be useful for controlling pigeon populations, although bringing in peregrine falcon pairs seems to be an adequate answer already.

To be fair, the video presents a shotgun-mounted option 48 seconds in.
