To be clear, they crashed into the vertical cable hanging down from the end of the crane. Not into the structure of the crane itself. So it's not as bad as "they don't see cranes". But it absolutely raises the question of whether they can see cables , whether hanging from cranes or spanning telephone poles. And honestly, cables are really hard to see in the air. That's literally why high-voltage power lines hang thos…
I feel like soon kids will order the cheapest thing on Amazon for the free drone it comes with.
Earlier quoted context omitted.
mmWave is the usual solution for this; I know that Amazon were at least testing using mmWave but I'm not sure if it made it to their production drones.
Would that act like radar in mmWave? Send out pulses and see where they come back and time difference to estimate range?

You may have a tall mas or an antenna and massive cables stretching at angles around it for support. The distance between the base of the mast and the base of supporting cables can be quite large, so even a simple logic like "stay 100m away from tall structures" can be insufficient. It would be interesting to see what comes out of this investigation. Hopefully the injured person will be alright.
>so even a simple logic like "stay 100m away from tall structures" can be insufficient. Wasn't this problem solved thousands of years ago by euclid?

> Never fly underneath anything? This honestly seems like the obvious approach. Even if we suppose you have perfect sensors flying underneath something still means something might be dropped on you... why risk it when you can just fly above it?
https://www.theverge.com/news/790636/amazon-prime-mk30-drone... gives more information, including that * No one was injured directly, but someone was treated for smoke inhalation * The drones "were flying back to back" * They hit the cable of a crane (including a link to a video showing the crane). https://www.youtube.com/watch?v=E_ZpY6qHcTk
The video also includes a video clip of package delivery, where drone would drop package to the ground, which worked. But then propeller blew the package right into the bush was lmao.

I suppose recognizing that there is a cable even when we don't clearly see it, but we know it is there because we know the concept of a crane, is exactly the amodal completion of our brain's top-down perceptual inference that CNNs and whatever else those drones use are currently still lacking? It shouldn't be necessary to hardcore such things if the goal is to build something resembling intelligence. Of course for a…
Although I hear that Tesla is thinking about using AI for decision making as well, which I find quite scary. Frankly I think it’s safer if vehicles don’t have concepts and intelligence, and just follow the rules.

Long-distance transmission wires are sometimes inspected with helicopters, so I guess there are exceptions and protocols, but outside those, flying machines just aren't supposed to fly near cables except for explicit intent to catch them. Especially across or under. You may only approach in slow parallel motions and/or back off.
