Real Engineering explains how Zipline built a drone delivery network for medical supplies in Rwanda. It covers the fixed-wing drones, catapult launch, parachute drop and the logistics behind the service.
Why Hacker News points people here: HN points to it as the best explanation of how Zipline's whole system works and as an example of drones doing real, useful work.

“One of my favorite companies since I heard about them”
Commenter's favorite company, sees it as the way forward for delivery.
Full comment
One of my favorite companies since I heard about them - this video I personally believe this is the way forward, like in a star wars movie full of a plethora of "dumb" robots who have a specific work task, and are almost self sufficient. Like you have a robot that fix delivery drones, a robot that assembles them, and etc. Drones will be also much better at avoiding obstacles, and they will be much more efficient than cars. I am not really sure why there isn't more competition in this market. I believe they can build an autonomous delivery hub, and factory. I wish them all the best.

“one of the most interesting solutions an engineering perspective too”
Shows Zipline's drone delivery in Rwanda as an interesting engineering solution.
Full comment
Delivery drones are definitely unnecessary in densely populated areas. It's cool and futuristic, but it's not economical at all, it's very unsafe and also loud. However it's a wonderful thing for rural places with poor infrastructure. For example Zipline in Rwanda, one of the most interesting solutions an engineering perspective too: this video

Explains Zipline's catapult launch and parachute delivery system in Rwanda.

The catapult launches the drones into the air, which then parachute the package to the location. Real Engineering [1] and Wendover Productions [2] have really nice videos about their system currently deployed in Rwanda. [1]: this video [2]: link

Explains well how the whole Zipline system works.

I learnt about Zipline in a talk at JuliaCon by Tucker McClure who spoke about how they use Julia for designing and tuning their aircraft. Had the great fortune of spending an evening at the conference to learn more about the company itself, how it got started and their use of Julia. Recommend the 2019 JuliaCon video on how Zipline uses Julia for vehicle simulation: link And this video by Real Engineering that does a great job of explaining how the whole thing works: this video

“flyzipline is so cool!”

flyzipline is so cool! I saw an AMA they did on reddit a while ago and their tech for the thing landing where it hooks onto the the wire is really neat! this video

“with amazing (delivery of medical supplies in Rwanda)”
Amazing look at drone delivery of medical supplies in Rwanda.
Full comment
> Even if they're literally worse at everything than the alternatives, cost more, are less reliable, etc. Drones may be better for very quick delivery or where road network is very poor. See link with amazing this video (delivery of medical supplies in Rwanda) and mentions ship-to-ship transport.

“Really cool tech, the way they have a sort of assembly line for getting ready-to-fly parts on the package in the space of minutes”
Shows Zipline's assembly-line prep for life-and-death drone deliveries in Rwanda.

I was also going to mention zipline in Rwanda, last video I saw was two years ago but it looks like they’re doing well enough to be hiring interns in San Fran. Really cool tech, the way they have a sort of assembly line for getting ready-to-fly parts on the package in the space of minutes - these are life and death deliveries out here! this videolink

“The drone is not a quadcopter, they are too inefficient. Mini plane design.”
Details fixed-wing design, battery-GPS unit, rail launch, parachute drop and wire landing.
Full comment
For those blocked by a paywall, Real Engineering did a video on it [ this video ]. The most interesting aspects to me were: - The drone is not a quadcopter, they are too inefficient. Mini plane design. - GPS device is directly attached to the swappable battery unit to ensure it is always connected to a satellite, eliminating satellite connection delays when the drone powers up. - It is launched into a sky by a powered rail. It doesn't need to land to deliver the goods, the items get parachuted down. No infrastructure needed on the receiving end, the item just drops from the sky. - For landing the drone flies past an aircraft arresting wire while hooking onto it which decelerates it and causes it to swing down (suspended above the ground). Easy to retrieve.

They’ve been doing those deliveries in Rwanda for 6 years! Very impressive. This video has a bit more info and is less rushed: this video

Explains how Zipline's drone launches and lands in more detail.
Full comment
The website includes a video [0] that explains how it works in more detail too. It's quite interesting how they evade issues with landing and lifting the plane, lifting the plane by shooting it off a rail seems like a common approach but landing it by catching it using a small hook at the tail of the plane isn't that common I presume. On their website it says "Gas combustion vehicles break down, get stuck in traffic jams that prevent urgent response, and put human drivers at risk behind the wheel, particularly when the route is rough and treacherous. Zipline’s drones are battery powered and fly quickly and directly to their destinations, leaving ground vehicles behind." That sounds like an unfair comparison, a more accurate comparison would have been to gas powered drones. Is it still the case for gas powered drones that they're more unreliable than electrical drones? It's probably because of the weight of a gas powered engine in such a small drone no? [0] this video

If we're talking about fixed wing drones in rural environments then it does makes sense. A good example of that is this drone delivery service in Rwanda this video

“from the moment I saw zipline I thought their quick launching and distance was interesting”
Notes Zipline's quick-launch drones, wondering about military use.
Full comment
If you watch the video, at the end they show a road runner. I was bracing myself for the poor little guy to get blasted to atoms. Spoiler: road runner survived. I work in the opposite field of weapons but from the moment I saw zipline I thought their quick launching and distance was interesting. Maybe this is already how drones are launched in places like Ukraine, I don't know. I do understand that the road runner is probably much faster and able to intercept jets. this video I'm not really looking forward to drone warfare, tbh.
