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…

You can buy a gun. You can still (barely) buy model rockets. You can buy glass windows (which shatter into thousands of sharp pieces if broken). I want proper insurance, liability, etc. when things fail, and good risk management. I don't want stupid safety.

I see them selling in Target all over the place. When I was a kid you had to find a pretty specialized store.

It's very unlikely to kill someone, or even seriously injure them. You should be at least as worried about playing baseball or riding a bicycle around people.

The battery packs on those things have quite a bit of heft to them, hit anything at terminal velocity and it's gonna be pretty devastating.

Terminal velocity for these things will not be terribly high.

I wonder how this handles obstacles. The trails we ride are not wide open ski slopes, or rivers, often times they are tight/wooded trails. Would like to see how it handles "close following". Lastly, the part in the video where the guy just tosses it into the river was definitely mind-blowing.

I wonder how well it will work for surfing. Probably great for small crumblers and open faces; probably not so great at the Right: https://www.youtube.com/watch?v=_N_-vxfz4uw . Can you imagine how sick it would be to get this thing to follow in a tube at Teahupoo: https://www.youtube.com/watch?feature=player_detailpage&v=7w... !!

do you surf? Have you ever experienced the push of air that develops from a closing / collapsing tube?

One motor suddenly failed Maybe drones need to start to incorporate parachutes to slow down the fall in case of problems like these, or maybe even airbags to ease the crash. Not that it would make it 99.9999% reliable, but it should be better than nothing. And also won't completely thrash your drone when it crashes. edit seems nine_k already commented with a similar idea

Quadcopters can also be saved if only one motor fails using only the 3 other motors and an algo: http://diydrones.com/profiles/blogs/new-algorithm-can-save-a...

Recent research has had controlled landing on 2 motors in real robots (and one motor in simulation only). The main trick is to spin the whole vehicle around the z axis (up-down) very fast, and modulate the speed of the remaining rotors to apply forces at different places around the centre of gravity. IIRC the one-rotor version didn't work on a real robot due to limits on the frequency response of the real-world motor controller.

Well, you knocked those straw men down. I guess that settles it. Drones are exactly like windows aren't they?

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…

I take it you don't drive, or allow yourself to be driven, right?

This is cool. I've been dreaming about something similar. In my mind though it would be smaller and could hitch a ride on your shoulder.

I imagine that one problem is that if it's too small, it will be unstable in wind... So since they need a certain amount of weight for stability anyway, might as well devote it to big batteries (rather than being small and dense).

You're right. I wait for the day when we can make the batteries smaller / motors more powerful.

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?

Purchaser agrees to stay clear of anything in the range of the UAV, or anything it could possibly collide with such as power lines, buildings, other UAVs etc.
