Using a gyroscope, gps, accelerometer and some other sensors is not a difficult step to perform.

I completely disagree. None of those sensors would likely give anywhere near the accuracy, frame rate, or context of the current system. Also, there is the issue of where the computation is done. It seems obvious to me that the intended goal is a decentralized system, where every vehicle is autonomous and creates an internal model of its own surroundings. As best I can tell, in the current system all the computation…

It's pretty hard. This assumes the existing radio links can handle the extra bandwidth. I don't see a WiFi card, so they may use radios with low-baud serial connections. Maybe the radios are good enough that doubling the radio communications is fine. Now, all the new hardware means extra draw (and potentially extra batteries) on each quadrotor. They might fly with this extra weight, but it won't be nearly as long. Al…

In one of their papers they state that they use Zigbee modules for a 56kbit link.

Every time a see a new quadcopter video, I wonder to myself how long before local law enforcement starts using them. I gratly fear a widely used, easily weaponized, remote controlled airforce that local enforcement officers can easily obtain.

Surveillance drones were already used by the police in South Africa during the national elections back in 1994, in that case on loan from the Air Force. After further successful deployments in the years since, the SA Police Service is considering issuing an RFP for a small UAV fleet.

Conceptually, surveillance-only UAVs are not dissimilar from police helicopters, which have been used for decades without massive privacy issues. In fact, when evaluating the option between acquiring a larger UAV platform or additional manned helicopters with high-end electro-optical camera gear for the Football World Cup, the local police went went for the helicopters as they performed better in that specific role and there was no cost saving.

I don't see much chance of police departments weaponising UAVs any time soon either. Not only does it push up the cost significantly, but there are accuracy and liability issues that will take some time to sort out. At most I could see helicopter-based UAVs being used to drop tear-gas near crowds and even that's iffy.

Very cool, but notice what kind of room they fly in - they're using cameras to control the quadcopters, they're not autonomous, which means that if you put them outside, they wouldn't work. Still, pretty damn impressive.

There might still be some practical uses that do not require complete autonomy. I can imagine e.g. fleets of such quadrocopters flying inside buildings, tied to security cameras. Law enforcement would probably love this.

I enjoy how references to The Diamond Age are becoming more and more common in tech beloved by the hacker community. Increases my excitement for the future! I want my matter compiler already.

Anyone have some tips on the small components? Most of what I seem to find on the drone forums is about larger devices, maybe upwards of a foot and a half or two feet across.

http://wiki.openpilot.org/display/Doc/BumbleBee this parts BOM (from HobbyKing, mostly, so it's cheap) gives you a basic idea of what you'd need.

I built a similar quad using PCB milled on a homemade drill press for the center plate (rather than buying it laser cut).

I very much would love to set up a bunch of these quadrocopters to circle my house and use them as security cameras. I'm not sure how long it would take for that, but if you could set up something like 20 of these, have them continuously rotate around the house perimeter, recording everything, and then come back to recharge with another one taking off, I think that would be pretty awesome.

I think it's pretty paranoid. Why would you do that?
