Correction Lily - Quadcopter camera It is annoying that everyone started calling Quadcopter a "drone", which is a very generic term. Flippin non-tech marketing peeps. -_-

I don't think that's a correction. You are being more specific, but Lily is definitely "an unmanned aircraft or ship that can navigate autonomously"...which is what a drone is[1].

I was walking down Hollywood Blvd one day when they suddenly shut the street down for about 5 minutes to do a fly-by RC helicopter shot. This was a few years before lightweight drones and cameras were on the market and this helicopter reminded me of a flying lawnmower! As it whizzed by me and thousands of other people, I was pretty sure it could easily have taken off a limb. I have a fairly cheap drone with a built-i…

I believe NYT carried an article last year about an RC chopper flyer who got beheaded by his own chopper's main rotor. It happened in the Central Park. It was a large RC Chopper and something went wrong and he ended up get killed. He apparently liked to do some dangerous stunts apparently... However I would think these drones' propellers are shorter thus less dangerous? Any ideas?

In an avalanche you can't call anyone to save you. It will take them too long to reach you, and you'll suffocate before they can reach you. The chances of survival drop severely after 15 minutes of burial. The only people that can save you in an Avalanche are the people in your group. Source: Canadian ski patroller.

What if the drone has a 2-3m acuracy of the position? At least in ski resorts the bystanders can immediately rescue the person. Off tracks, it often happens that 1 person is aside of the snow corridor.

While not a bad idea, I think the existing avalanche rescue gear is better suited.

It's impressive, no doubt, but I wonder about the actual utility of the device. My main concerned is the 20m battery life/record time - that is pretty limiting. If I were to use this to record myself snowboarding (like the video shows), that would be a problem. Here in Colorado a typical blue rated mountain run is easily 20m from top to bottom, esp. if you aren't gunning it the whole way. When I ride alone I can mayb…

A bigger issue is that drone power consumption goes down as they go faster. Even if 20m at 25MPH is fine, you'll actually get less than that if you go slower. Hovering uses a lot of power.

I would think a multi-FC voting system, like what the shuttle used, would be the way to go for FC redundancy. Mix that with a dual power system and 6 or 8 motors and I think you get MUCH better redundancy and fault tolerance. And while you are at it perhaps a disconnected drogue chute that deploys if a watchdog signal is lost. Not something that is large, just enough to slow the decent to non-dangerous speeds.

that would be a much safer setup but don't see these consumer drones implementing all that!

A consumer follow-me quad with a youtube camera launched via kickstarter? Probably not. A future DJI aerial photography product with a 4000-8000 price tag? Absolutely. If Amazon ever intends to deploy these for actual package delivery instead of just PR they'll need redundant computers with a voting system, fault tolerant flight control algorithms with some kind of fault case detection and some kind of failsafe parachute / alarm system to slow down descent and alert anyone on the ground of an incoming object with 16+ razor sharp carbon fiber blades.

To say nothing of things like active sonar/lidar avoidance and a secondary navigation system of some sort for when GPS is unavailable.

As someone who has flown RC drones and heli for the better part of 5+ years now I generally find that there are 3 camps: 1) people who have never flown and assume the worst and often want unrealistic "guarantees" (see above), 2) those who fly, fly often and fly as safe as can be "guaranteed", 3) those who fly in an unsafe manner due to inexperience or just general carelessness. I've always tried to fly responsibly at…

I fall into camp 3. I have a DJI Phantom that I crashed into my neighbor's yard due to my own incompetence and inexperience. I'm not arguing for draconian policy measures. I just want manufacturers to focus on and market reliability and safety features. It's a win-win for users and manufacturers. Manufacturers are clearly aiming for these drones to be everywhere and for everyone to own one. With many, many people fly…

Don't get me wrong, I fully understand the point you are trying to make. The problem I have with it is, it seems by your own admission, you're somewhat hypocritical. You'd like for someone else, a la the manufacturer, to provide a guarantee that you can be lazy and not take precautions so that you don't have to worry about a $1300 radio controlled vehicle that flies doesn't hurt someone else?

I only mention the general cost because - there's not that much margin in these things to achieve what you want. Nobody will spend $2300 on a Phantom if that additional $1000 is for upgrades to safety and ignorance factors.

There are many things that didn't start out with any guarantees of implied safety - and many things that are assumed safe, when not operated safely, are inherently very risky / unsafe.

Finally, there are easily many tens of thousands of hobby grade drones out there - flying daily, operating (for the most part) safely (again partially dependent on operator). How many deaths have occurred to date?

Something that really bothers me is that when I first started flying the general reaction I had was of excitement - although I was generally no less cautious. The RC craft I flew drew interest and excitement from bystanders and it was generally a good experience. Now, I am overly cautious when flying anywhere near public areas. I've received comments about how I should "go somewhere else", even when I was flying in an area where there were no people, but someone decided to seek me out since they saw the craft from remote. And I've generally just tried to stay out of places I know would be potential hazards if there was a malfunction where I lost control.

Do I still fly in "tight" locations? Yes - I do. I've flown my neighborhood to assess storm damage for my neighbors knowing that there are people - but in those situations I always fly with prop guards and try to fly over houses, not over sidewalks or roads. And then there's the artistic side - I like taking shots of architecture and some of those situations require thoughtful planning or waiting for an area to clear.

I can't help other people's ignorance and I will say that you flying untethered with no experience is not something DJI or I should have to worry about - that's your choice and risk to weigh. If I was your neighbor I'd have a frank conversation with you about your actual skills and ability to ascertain risk.

In my opinion golf is far more risky than flying "drones" (I prefer RC quad-copter, but to each their own). I play golf, I love it. I'm not going to stop playing because you hit golf balls off your deck into your neighbors yard and then expect Titleist and Callaway to fix your bad decision.

This is really, really cool. That said, flying objects are inherently dangerous. I was at a bike race and a guy was following the pack with a DJI drone. One motor suddenly failed and the thing plummeted to the ground from 40ft and broke into a bunch of pieces. Luckily, it didn't hit anyone but it would have been a major incident if it had. There's a lot of excitement about the cool, flashy features of these drones (f…

Can't really find this on the site but does it have any sort of collision avoidance? What if I am running on a sidewalk and it runs into a tree branch above?

Is the 'hands-off' recovery not good on the DJI platform? I've always used OpenPilot FCs so have no idea how well the DJI FC works, but the OP hardware will fully recover from stupidity if you let go of the controls (while not in acro mode).

Fail safe works reliably in my experience - but it doesn't save from risky flight in the first place. I think YMMV, but I've yet to have an in-flight failure that resulted in crashing or losing control. That being said I'm overly cautious about inspection and maintenance of the craft I own.

I'm not disillusioned though - it will happen, I'll lose an ESC mid-flight and I'll have to deal with trying to guide an uncontrollable aircraft that I may not have line of sight on. Pretty much next to impossible to guarantee anything in that situation.

Awesome, but my experience with current-gen pseudo-autonomous UAVs, these questions immediately come to mind:

Can it follow you around the corner of a building without clipping it?

Can it avoid bumping into a tree?

Will it climb above the trees to follow you through a wooded area?

Can it avoid getting tangled in an overhead utility line?
