Actually, this building behavior is pretty complex. Another design team has done something similar. A group of five somewhat larger flying robot quadrotors assembled a six-meter tower made of 1,500 polystyrene foam blocks at France's FRAC Centre. (You can access a video here.)
The lack of technical information from the GRASP Lab may be because it is participating in the Scalable sWarms of Autonomous Robots and Mobile Sensors (SWARMS) project, which has military-related goals and is associated with the Army Research Office and the Army Institute of Collaborative Biotechnology. SWARMS combines artificial intelligence, control theory, robotics, systems engineering, and biology to apply biologically inspired models of swarm behavior to large networked groups of autonomous vehicles, such as deploying them to carry out a predetermined mission and to respond as a group to high-level management commands. These robots could also be used in rescue missions after natural disasters.
The KMel Robotics Website consists of a single page and a photo of the quadrotors, but it promises more information. Along with the 5.5 million other viewers of the latest YouTube swarming video, I hope it comes soon.
Jack, most of the swarming and flying robots, along with a lot of other robot research, seem to be funded by the military, usually DARPA. The one I mentioned also appears to be aimed at military applications.
Warren, I hear you. The huge advances in semiconductor shrinks and system-on-chip have made processors and memory capable of such feats, as well as big reductions in sensor size and rise in abilities because of MEMS technology.
Jack, wait 'til you see the much smaller flying bug in an upcoming robot slideshow: it's about the size of a quarter. I think that one will fit under the door. Not only that, but these are self-assembling: shades of Crichton!
It's funny how we used to think about how much memory it would take for such a task and know it was totally unrealistic. Now, it is reality. We have the memory and processing power. Now we just have to work out the "bugs."
The robots use some kind of continuously adjusted mapping functions to locate themselves in space and explore unknown environments, as Kumar states in the TED talk video:
http://www.ted.com/talks/vijay_kumar_robots_that_fly_and_cooperate.html I don't know if that technology is based on SLAM (Simultaneous Localization and Mapping), but I wouldn't be surprised. It's pretty popular for this type of application.
BTW, the robots in the story are the same robots from the U of PA GRASP Lab that play the James Bond theme in that video.
Hey, oldtimer8080, I did read PREY. It was very scary. In fact, I thought of that book when I saw the first video on these little robots, although I think they are also cool. I hadn't thought about the invasion of private property issues, good point. Your 'tude sounds like the 'tude of many of my neighbors up here in the mountains.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
