Modern robots have already learned to get up after falls. And some of them do not even hide their plans to destroy humanity. Against this background, the invention of Finnish farmers who attached a chainsaw to a quadrocopter looks very reckless.
The inventors designed their fantasies about the destruction of defenseless snowmen with a drone with a saw in a small video. By the way, a dangerous drone can also be used for good purposes - it is quite effective at cutting off icicles hanging from the canopies.
There is some good news, too. A destructive drone can disable regular balloons.
