Then they shouldn’t be flying in your city. As is apparently becoming obvious.

I can’t think of a major city I’ve been to on earth where 10M from a hung cable is realistic outside of some suburbs and rural areas.

Does Manhattan count? I am pretty sure south of 96th street has no above ground utilities.

Probably half my immediate neighbors get an amazon delivery a day. The truck makes sometimes two or three stops throughout the day and is there for like 15-20 minutes running packages. The thought of that replaced with drone traffic is crazy. It would be like dozens of landings and overflights per hour. It is already bad enough when the realtors fly their drones overhead. I can't imagine the birds and bees aren't get…

Same. Even outside the holiday season, there are 5+ package truck deliveries/day on my little street (12 houses). That's UPS, FedEx, USPS, usually multiple Amazon (which always surprises me), plus a couple unmarked vans. Plus couriers in cars. Plus food delivery, at least 2 a night. Almost all the Amazon vans are now electric Rivians or GMCs. That's a LOT of drone traffic, given there's near zero ability to double up…

I recently started seeing electric delivery vans from IKEA in my city. One thing I really noticed: They are whisper quiet compared to diesel trucks.

Fucking, learn it from the self driving car companies. fly your drones for at least 6 months in the city, make high resolution 3d maps of the area, identify the no fly zones, train models on these. I can't believe their drones are crashing into stationary cranes.

A commenter here notes that detecting power lines is a really hard problem. However surely there is a set of simpler solutions to the problem than actually trying to spot power lines.

This sort of thing is a largely solved problem for bigger aircraft and a similar approach with quite a lot of international regulation and agreement seems to be needed.

Drones could be given a cross section of airspace to work within that is say a horizontal slice about 50m to 100m above ground level, with various rules on resolution (ie what constitutes ground level at any point on the planet). The minimum height should clear most obstacles that are hard to spot. There would be flight corridors defined between take off and landing zones. There would be exclusion zones around areas such as air fields and military locations etc.

Drones could even be allowed to use commercial airspace provided they follow the existing rules and are detectable and contactable etc.

The tricky bit is working out take off and landing zones and rules for them. At the moment, aircraft try to avoid flying over habitation zones. I live near to a helicopter factory and used to work there so I have some idea of the issues involved.

There are lots more rules that could be added for safety. For example, requiring height when flying in a non corridor depend on direction. However, I'm only allowing a 50m zone here but then a drone is only about 1m "tall". Even something as simple as divide the compass up into say 16 zones for wind Beaufort 0-2, eight zones for 3-4, four zones for 5-6 and ban flight at 7+. Those wind designations might depend on gust speeds or constant and could be transmitted. The idea is that things get a bit random as the wind speed increases. Divide the allowable height by the number of zones and set your height accordingly. So flying directly north will be at say 50m and directly south at 100m. The wind speed should also indicate the density of drones allowed per horizontal area. That will need some experimentation and legislation to determine what is "acceptable".

I used to work in perception for autonomous aerial vehicles and horizontal wires were the hardest common object to avoid. Traditional stereo won't help you localize them -- wires are thin so even mere detection can be hard, and one portion of a wire looks much like another so feature matching fails resulting in bad or no depth estimates -- and LIDAR sacrifices resolution for weight and power consumption (which both h…

Cables don't move often. Why not simply have a map of all of them? Google sell maps of things like this from street view data.

Any one particular cable might not move often, but if a telco owns N bucket trucks it's a safe bet that about N cables move every workday.

Telcos are notoriously secretive about the location of their fiber. They even got most state legislatures to exempt it from state-level FOIA laws.

It’s really hard for people too. The advice I got for landing in a field was to assume that every pole you saw had wires going to every other pole. Which is reasonable enough for that scenario, but not workable for continual low altitude flying in a built up area.

> horizontal wires were the hardest common object to avoid... Traditional stereo won't help you localize them This makes a lot of sense. I wonder if it wouldn't be better for autonomous vision to use three cameras instead of two for better spatial reasoning.. maybe in a triangle pattern?

We experimented with a rig with more cameras on it (four, in a square) but the baseline of the cameras on the drones we were using could be measured in centimeters, so the vertical stereo pairs didn't provide much better results. Further, more cameras means more power, more weight, and much more expensive on-board processing (which also will require more power).

This dream is naive. One truck rumbling (or humming, in the near future) through your neighborhood delivering packages to each of your neighbors over the course of 30 minutes will be replaced with one drone per neighbor. If they must exist, I hope they're priced/taxed such that they're used sparingly.

Bit of a travelling salesman problem, but I think a hybrid approach would be optimal. Have the delivery van drive to a neighborhood, then release drones from the van to deliver packages to individual houses.

Now instead of just one truck for a whole route of deliveries, or one noisy drone per individual delivery, we get multiple particular corners in any given area where the sound is concentrated like a buzzsaw testing facility every day because that's where the Amazon dudes like to park and release the drones.

It'll be awesome when they decide that the parking spot in front of my house -- with no trees or overhead lines -- is an ideal place for drone staging.

(And no, I'm not particularly worried about any of these noise issues. I predict that it'll all sort itself out just fine. Besides, I personally think the spectacle of a swarm of package delivery drones leaping forth from a truck is something that I would never tire of observing.

But it is fun to think about the problems and the solutions. The deeper one dives, the more complex they get.)
