It would be cool if the remote in your pocket had a "Call 911!" button. So like, if I was out snowboarding, and saw an avalanche coming, I probably wouldn't be able to call 911. But this little drone is a good deal above me and the avalanche/murderer/shark/whatever, it could call 911 for me, and when they recovered it, it would have video of what happened to me. It could even fly towards a preset location (known rang…

Agreed. I also want a drone that can carry and emergency supply kit and drop it to me like Katniss if I get into trouble. If I'm running through the Grand Canyon and get bit by a snake it can drop/deliver snake anti-venom to me. Could also go over to a ranger or resupply station and bring other supplies.

Exactly. If you are flying over people AT ALL you should be using an octocopter at least.

What about an hexacopter with opposing rotors (Y configuration)?

It provides some redundancy, but 8 motors is better in that area IMHO.

Dawn of the personal drone/robot/servants. I'm wondering if it's able to navigate around tree branches or corners without slamming into anything as opposed to the wide open spaces they show.

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.

But you will have a video of your death.

I'm not a web designer: just wondering, how does someone go about designing a website with such animations as you scroll? I know there are a lot about these days; are they all custom, or is there some tool chucking all these out?

with anything there are a lot of ways to do it. This is sort of a parralax type of animation. There are many librarys that handle this, but one way is to (at a certain place on the site) decouple the scroll from actually moving further down the page, and use it as the keyframe engine for the animation.

This is a basic overview, but if you are interested google keywords like "parralax" and "parralax animation"

it can still drop from the sky, you are just getting a bit more redundancy on motors/props but doesn't help if they all stop due to something else

Yes, a critical failure of the flight controller or power system can still cause it to fall from the sky. I've never had that happen personally and I've logged a lot of hours on custom built quads.

If you are using alpha/beta FC firmware or your settings are still being tweaked you shouldn't anywhere near people anyway.

I've lost engines that resulted in nasty crashes. As I fly quads almost exclusively they are always nasty. As such, I never fly over or near people (other than myself).

I've read of full power loss, but never personally experienced it.

In any case I think I'd be more afraid of bad FC firmware that resulted in a fly-away event. Those are super dangerous as the machine just takes off into the air and away from you. That has the potential to be MUCH worse as the altitude they eventually fall from is significant. If you've never seen a full-power ascent of a multicopter then you're in for a surprise at the speed at which they can disappear while going straight up.

Just a personal gripe, but I hate it when websites don't work without the pointless www. in front of their domain. I just text a friend to visit https://lily.camera and he'll never see it, because it doesn't exist.

While I agree they should make www redirect, its not pointless. If you serve sub domains or plan on serving them, www as your primary helps differentiate cookies.

Point taken. But I doubt this sales page will be implementing subdomains anytime soon, if ever.

Safer maybe, but nowhere near as swift and agile as a multirotor, and much more susceptible to wind.

Why, it can still be multi-rotor, and even capable of bigger payload with the same battery. The air drag from the balloon will be an issue. OTOH the motors could be run at low power when cruising and at high power when speedy maneuvers are required. The size will definitely be bigger. But if we talk about professional-grade drones (for video reporting, etc), they are large and expensive as they are. Improved safety a…

Could the airship configuration be a recovery mechanism? IE, instead of having a parachute or airbag to soften the landing, have compressed helium release into an airship and then continue powered flight with whichever motors remain?

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…

HyperBlimps are a lot safer, silent and mellower photography platforms than drones. Not quite as portable, and you need a tank of helium, of course. But equipped with solar panels they can stay up indefinitely, and built with transparent plastic they can be almost invisible in the sky.
