Apparently based on the hand device.

i think the question is what tech does it use do accomplish this

Yes this is what I was wondering. Some brief searching on similar devices suggests it's a combination of precise sensors and algorithms to tie everything together.

The minute drones like these start shipping they'll be banned from all ski resort faster than you can say pow. Also, with a top speed of 40 km/h this isn't able to keep up with anyone who's past the rookie stage skiing/snowboarding. So their marketing is very misleading, either by intention or because these guys don't know shit about skiing.

Anyone going faster than about 40km/h isn't really doing anything worth filming anyway, other than ski racers. All the interesting stuff for filming on the slopes happens at relatively low speeds - park, moguls, jumps, butters, etc.

If you're going any slower than 40 km/h the only thing you'll be doing in a terrain park is falling on your face. This [1] cable-driven terrain park "for children and adults" pulls you at 40 km/h. If you're looking at landing anything bigger than a 360 you'll need to be going closer to 60 km/h. Ski racers are not happy until they're going (a lot) faster than 90.

This is the big reason people don't buy these types of drones (this one certainly isn't the first of it's kind). It doesn't have obstacle avoidance or it will make a massive deal of it.

Intel last keynote demoed very capable drones. They're showing it off, it won't be long until it hits the market. They named the components RealSense, a miniature kinect I guess. Nice demo at 4:55: https://www.youtube.com/watch?v=Us0BqJvsF9k&t=295

Now shipping in mobile phone size - http://www.pcworld.com/article/2907352/intel-shrinks-realsen...

Shame the dev kit only has Windows support.

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…

Couldn't the same be said for any technological advance. Waiting until anything is perfect is waiting too long.

Sorry, what? How on earth would this be better than a headlamp, apart from the "look at my drone, my drone is amazing" part?

> "look at my drone, my drone is amazing" This is actually a fairly compelling reason to do things.

True dat. But then the lamp part is just extra weight that also drains electricity from the batteries.

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.

The biggest showstopper for me on this is the hugely disappointing top speed (40 km/h). I'm an alpine skier (ex-racer) and the only times I go that slow is on transport stages. This thing literally wouldn't be able to keep up with Usain Bolt running the 100m. It needs at least twice the top speed.

It's not hard to make a quad fly 150km/h - https://www.youtube.com/watch?v=JO85qrlUqkw.

Obviously gets quite dangerous in populated areas like ski slopes.

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

Drones of this size are cheap enough that the extra weight and cost of engineering of safety devices generally isn't worth it. It's easier to fix or replace parts.

The max speed is 40 k/h - I'm no expert cyclist, but what happens when you go 60, 70, 80 down a long hill? Can the Lily catch up to you, and up until how far? What happens if it can't?

It would get left behind. It looked like there is a little handheld GPS/wifi beacon used for follow me. My guess is RTL (return to launch) as a failsafe once you get outside wifi range
