Love it!

To me the message of this demonstration is much the same as Discovery Channel\'s \"how it is made\" show which features a lot of machine-made production techniques. The point of that show, to me, is look at how much production can be done so well by machine, if one is clever enough designing the machines. The quad copters move and hover really well, so long as they are inside that is. Once they get outside into the wind and rain, I don\'t foresee robots like this building much practical structure. In CIM we have a phrase, \"lights out production\", which means turn off the lights and walk away from the factory, and when you come back in the morning you\'ll be greeted by mounds of machine-made finished product. Or, you might get a phone call at 2am from the robot overseer telling you a carriage had jammed and can you please come troubleshoot? Straightaway?

Great work by machnes

I wouldn\'t call it great because the swarm didn\'t really work like a swarm. Slow and tedious process. When you make ALL OF THEM do the task at hand together - then it\'ll be cool and progressive. :P

@Grunchy - A reasonable amount of wind turbulence compensation per craft and object weight is simply a math problem. Automated flying vehicles of all types (drones, unpiloted helicopters, etc.) already have this. Smaller drones can have it too. In fact, wind issues can be eliminated completely if a full circumference windshield for the current layer (floor) is steadily risen to each successive layer as it is constructed.
Rain and water resistance is purely a matter of constructing the craft to be waterproof and also modifying the flight algorithms to handle downward and sheer rain forces.
No... not easy, but certainly not impossible. After all, isn\'t that what engineering is all about; the study and application of techniques to construct and do what you want done in specific or variable contexts? I imagine that one of the future areas of research will be exactly the operation and required design considerations for operation of these craft in less than perfect weather conditions.

SkyNet was able to boost its power incrementally by sending agents backwards in time to develop the very technology upon which its existence was based. The innumerable cycles of time exchange which were conducted can never be analyzed because of unobservable quantum entanglement processes used to maintain and expand the original sub-picosecond-scale time loop. Similarly, the vast quantities of electrical power used during the cycling process could not be billed or even measured, because all historic traces of those events were absorbed as a side effect of tachyon decay.
The Skynet agent-bots were carefully concealed beneath life-size avatar projections such as the \"students\" shown in this video. They did technical work and, more importantly, gradually persuaded humans in the target time period that such research and development was in their best interests - an astonishing achievement under the circumstances.

Slow and tedious process may not b impressive, but the impressive part of this whole thing is dat no matter how long it takes, they CAN do it.

cool, great job with the current technology,
the borg would be proud

Somebody check on ralph.d ...something\'s gone horribly wrong with his controller.

For those of you who say that it is a slow and tedious process, yes it is, but only with that number of robots. If they had 100x as many, the work would go fast. The reason why is is so slow is because they have to go back and get charged very often.
