Interesting, but robotic cranes on the ground would seem to be more efficient and reliable in ordinary circumstances. It's not a question of how to grip it, It's a simple question of weight ratios.

A couple of years ago I've watched a documentary about crane operators working in a harbors. They were payed incredible salaries and it was stated that they won't be replaced by robots because of their capabilities in decision making.

This lab has several other videos with quad rotor robots like this (e.g. http://www.youtube.com/watch?v=MvRTALJp8DM), but don't worry about them escaping and starting a robot domination: they rely on infrared motion capture systems in that room for extremely precise location sensing.

Once GPS gets sub-meter accuracy, then we should start worrying.

Pretty neat! I'm sure they'll get to it eventually, but there's no advantage to having three drones in this demo, since the work isn't pipelined. It seems that a drone has to wait until one finishes picking stuff up before it can pick up something itself.

Right, but they're saving travel time. When one drone is flying back to grab a piece, the next drone is lowering a piece into place.

What you say makes sense - robotic cranes should be able to operate with heavier pieces, and will require less energy per piece placement. However, MAVs (micro air vehicles) could reach into places where cranes wouldn't be able - i.e. inside the building. Also you can have many more MAVs working at the same time than cranes, so MAVs might be able to considerably speed up the building process.

They're also a lot easier to move and set up than cranes.

Great fun, but I suspect NIMBY concerns would kill any practical application.

Let's imagine they get the machines scaled to the point when they could build an actual habitable structure, and that they sort the power concerns that I suspect would make it insurmountably uneconomic.

Now, imagine a squad of sufficiently large and powerful helicopters buzzing away all day next to your office. How many people are going to be OK with that?

If robotic ground based cranes can't reach inside the building, then for the most part, neither can human workers [making similar adjustments for scale]. Robotic helicopters might have advantages where helicopters are currently used for construction. But those are limited cases.

Generally, the duration of construction is determined by economics and weather. Flying robots probably don't provide an advantage on either front.

There may be some applications for MAV's for the inspection of construction. But there's an off the shelf solution already availible [http://www.amazon.com/Air-Hogs-Hawk-Eye-Channel/dp/B00395EJR...]

Well, that and incredibly beneficial union rules. Lots of work printing cargo manifests, handing them to another person who types it into another system, and so on. But it's ok, that process only adds a marginal amount of delay, error, and cost. It's better than getting shut down by a strike, right?

Earlier quoted context omitted.

There's no reason you can't combine these approaches. Using larger ground-based equipment to move girders and small, flying machines to do things like interior finishing makes a lot of sense.

A 4x8 sheet of 1/2" Gypsum board weighs nearly 60 pounds. A five gallon bucket of paint weighs about the same. A quadrotor couldn't finish an office because it would be too large to fit through the door...never mind the rotating blades.

Great show, but there needs to be another device (carried by the quad rotors) to create very strong bonds between the parts. If the quad rotors could carry this bond-making robot that temporarily attaches to the parts and joins pieces with adhesive/nailgun/puzzle-piece fit, then they would be on to something.

Make a structure of actual use, like a tiny bridge across a moat that could hold people. The magnets have got to go.
