I mean like... there's a camera... on the waldo... I was impressed by the FPV setup in the buggy... the truck blows me away...

That was a terrible launch! Seriously, that was BAD. Good thing it's Fiberglass.
Having flown FPV aircraft before they would have been better off with one of these: http://www.fpvmodel.com/latest-version-skywalker-2014-1800mm-fpv-rc-plane_g6.html
It would have cost a ton less too...

I upvoted for FPV GTA V

Do a search on the Proto X or Syncro from Estes. They are great little quads.The Crazyfly doesn't support FPV, they have a small programmable quad (Which is quite an achievement BTW, not to downplay what they have done, and the multiple features make it a pretty cool little platform). But Is not really all that close to the Pixie. They removed all of the plastic from a #19 Keychain FOB Camera(You can find them all over Ebay) to save weight and are placing it on top, it can only record and not broadcast, hence no FPV as shown on the Nixie. The induction charging is very cool, and I don't know much about it but it seems like that would take a long time.
A gauntlet is a much better solution IMO than what Pixie is showing. It can then be used as a home location as well as something for the quad to track. It is also very similar to what AirDog.com is doing with a wrist band.
Thanks for the link on the crazyfly.
FYI, I'm not saying that certain things in the Nixie are impossible (Many of the individual pieces are possible in some form) I'm just saying that as they present it in their video it is not currently possible, nor do I see it being available for purchase by open market consumers within the next say 3 years. But I do think that you will have "Dronie" based quads in several different form factors, including wearable, pretty soon.

Hmmmm. Perhaps it should be FPV? Or maybe they have tiny guns?

Yeah, but they are looking for funding, so someone is going to pony up. I watched the video. Most of what they show is a Hubsan FPV quad that you can get through places like Banggood it uses a spreadspectrum 5.4 system to broadcast the video and a 2.4 system for control, but it does not have any autonomous capabilities. Hubsan makes some of the best stuff out there and we work very closely with them. The wrist thing is cludgey, and while it conveys the idea (You can see the needed twist I was talking about), it wont get them anywhere near their presented final design. Wifi would be an option, but it would require a wifi hotspot be built into the quad. I know we aren't talking about components that require a bunch of power, but we are talking about small batteries, so every mV counts. Especially for something that is wearable.
Now the Hexo+ is very much like the Airdog. Both seem very viable and are using existing technologies. My only concern about either is what do they do about object avoidance and low battery response. In either situation you can wind up losing the vehicle or injuring someone. Most higher end quadcopters have the ability to Return To Home (RTH) which is great since the pilot is in a stationary position, but put a pilot on the move and things get weird. If you are out surfing and the quad gets a low battery warning due to either a battery failure or having been waiting for 30 minutes for you to catch a wave, where does it go? It could go back to the take-off position, but if you drifted from there then it will need to calculate that distance and make sure it can get back. Salt water and electronics don't play well together. If you take your quad with you for a ride on a skateboard down the boardwalk, how do you make sure it doesn't hit a light post or a tree while it is zipping after you? You could fly at a higher altitude, but the zoom lens on the camera may not be enough. Hexo+ has a video of the founder riding a skateboard while the quad films. Notice that he stops short of going into the wooded area. I wonder why?
There are issues, but at least in both cases I think they are starting from proven technologies and have footprints that are achievable.

The slap bands don't work because the arms are at angles to each other. Slap bands can only rotate in a straight direction (They are basically tape measure metal), so they wouldn't be able to come back to meet in the center like they illustrate. Also they have the motors all prettily lined up and facing directly off the wrist, that would require the material to be able to twist.

For the rotor size, these are fixed pitch rotors. You can change the pitch of the rotor to give you different flight characteristics and in general you have to match the pitch to the motor to be the most efficient. I may have this reversed, but a lower pitch prop gives you more torque and less overall speed, but a higher pitch prop gives more top speed, less torque. Making a prop that can be injection molded at that size that even works is difficult, making one that is super efficient would be even more so. QC would have to be incredibly exacting. As a gauge, the 2" x 2" quad has 1" props. They can lift it and buzz it around pretty well. Those things were a pain to get correct and I have a hard time imagining anyone making them more efficient than they are. In the case of the 2" quad, we didn't even paint the body because we want to limit the impact on flight time from added weight. All molded in color. That's how sensitive these things can be. There are better motors if you are willing to pay, but even then it may not be enough.
Go Pro records in HD, but doesn't actually broadcast anything (plus it is big enough to keep this thing from flying anywhere). If you want to broadcast video you have to do it in 640x480 tops. To do that you need something like an FPV system that broadcasts on a spread spectrum. If you went bluetooth you have an effect range that is pretty small. Wifi requires more power to get a longer range. A video transmitter system would require a separate device to attach to your phone to receive the signal and translate it to a PPM signal for through the headphone jack. But a VTX is pretty heavy as well.
And things may drain just a little bit of power, but it stacks up. At most you have a 250mAh Lipo battery that can fit in there. That isn't going to buy you a bunch of flight/video time.
Video on the phone is going to be subject to interference, so you would want to record on the quad. this would get you HD quality, but also adds weight, which means more battery draw, which means less flight time.

Just got 2 points, so I might as well use them to *promote something I believe in.
These new FAA regulations are terrible. Plus I just got 2 pair of FPV ski mask goggles working and I'm looking forward to building a FPV Sky Hunter.
