Jamming drones is easier than you think, the new battleground will be autonomous flying to avoid trivial radio/gps jamming. MIT has open source code for this already. https://www.youtube.com/watch?v=_qah8oIzCwk https://github.com/andybarry/flight

I'm no expert but how autonomous works if there's no positioning methods involved? (To avoid GPS/GLONASS,... Jamming)

Fused dead reckoning can work, especially if you mix camera and IMU (or more than one IMU!).

Technology like this is why The Wall is a waste of money when it comes to deterring drug trafficking.

Battleground? Are there many problems with Kalman filtering and preloaded maps of a path?

Not only that, GPS jamming can be overcome with better antennas (phased arrays of such, even retrofitted to existing commodity receivers) to eliminate jammers which are not more-or-less directly above the vehicle.

It makes me happy to see that people are venturing out and building something that takes longer and has a higher failure rate that web apps/software.

Yes, nothing is more depressing than listening to the a16z podcasts where they're discussing the minutiae of well-established b2b saas strategies for capturing long tail revenue. Shit, let's build some robots instead.

Fine and dandy when flying over a desert but when the drone meets the city and an "autopilot" failure occurs over a freeway/highway/street or someone's head the consequences will be unforgivable.

I don't get that. Before the sun rises tomorrow, for the US alone, 32 Americans will make a mistake with their car that kills someone (potentially, but unlikely, themselves, 2 will kill themselves, 29 will kill someone else, one will kill 2 others, for a total of 33 deaths). At the same time, a further 2000 Americans will injure someone with a car, and another 3000 will cause severe (I believe > 1000$) property damage, mostly on cars.

That's on 260 million cars, or an accident rate of something like 1.3% on a yearly basis (unfortunately, this masks the fact that ~70% of those accidents are done by That, we find perfectly acceptable. Drivers that crash cars about once a year are not that rare. And it's not like these people are the ones having minor accidents. Maybe it's just me but ... weird how people's sense of risks work.

This reminds me of Passerine Aircraft.

I believe they are also attempting to take advantage of runway-less takeoff and fixed-wing flight (more efficient than four fans pressing down). https://passerineaircraft.com/

Am I correct in understanding that Volans-i has two propulsion systems?

Of all the things I think this will really impact, I think food delivery and fresh ingredient delivery will be near the top of the list.

It's a little sad that people's first thoughts about tech like this is "It can bring me goods faster than FedEx!" That's such a trivial thing to use it for. Emergency deliveries in rural areas are where this will be most useful. Getting medicine and mechanical parts to remote places during crisises is hard .

Is there a reason that air drops are unsuitable? The new thing here seems to be VTOL. Fixed-wing UAVs can carry an order of magnitude more cargo the same distance.

No, nobody finds that acceptable. Until you stop misrepresenting the people on the supposed "other end" of your "discussion," no one is going to engage you in a real discussion about it, which is (unfortunately) probably why you still continue to think and act this way.

Well, yes. Maps aren't accurate (when it comes to moving foliage, as in the video, there maps are out of date within seconds, less in strong winds). Maps don't include many things that are moving, and maps just generally don't work very well at small scales (like the scale of an, even a large, UAV landing)
