Drug smuggling: Underwater drones seized by Spanish police


​

Armed with GPS navigation systems, the vehicles could potentially be operated by drug traffickers from anywhere in the world using an internet-device as simple as a tablet. Among those arrested were a father and son, one of whom police say was a qualified helicopter pilot who had the technical knowledge needed to build such sophisticated vehicles.

 

Drug smuggling drones

 

It's a worrying trend ... what's next? urban shootouts between gangs using clandestine armed drones?

 

Something like this?

 

Video shows a homemade robot dog firing gun. Should you be worried?

I'm waiting for the shootout by their kevlar wearing pet monkeys!

​

Not afraid if it takes 10-seconds to aim at a stationary object. And those legs don't look like they'd stand up well to return fire.

 

I was watching the news coverage of the Ukraine war, and wondering why it is still necessary to have people inside the tanks.

Surely the families of the dead on all sides are asking the same question.

Can you imagine the effect on the drone from the recoil when the gun is fired?

Isn't there some recoil-cancelling tech that could be used?

That is called rocket power.

I would think that the recoil would be enough to flip the drone. It's simple physics.

I mean something like a small mass ejected in the opposite direction at the moment when the bullet is fired. This would prove more complicated and would add significant weight, of course.

I couldn't imagine the ringing ears after that explosion just outside the tank - then the one crew member gets out and starts talking on a radio/cell phone.

One way is to fire two bullets in opposite directions.

yes, that is more or less what I meant ... but it's highly inefficient and cumbersome, of course ...

Or you can kill two birds with one fire.

It’s called hydraulic suppression whereby the recoil is dampened and converted to heat. There is also gas and mechanical/friction suppression. Some recoil energy is scavenged and used to load the next cartridge. Even bigger problem is getting rid of barrel heat hence rotating barrels or coolant jacketed. That or a very low rate of fire.
