Researchers at the University of Colorado at Boulder are developing small, swarming robots -- dubbed by the team as "droplets" -- that will be able to accomplish a variety of tasks. Possible uses include building a space station or a satellite, self-assembling into a piece of hardware after being launched into space, or cleaning up an oil spill on Earth.
Swarm robotics is a fast-changing, quickly growing area of robotics research and development. We've reported on a swarm of "hedgehog" robots being developed by Stanford University to explore space, and swarms that can play Beethoven, or repair coral reefs. We've also reported on the robotic self-assembling pebbles developed in Daniela Rus' Distributed Robotics Laboratory at MIT, where the leader of the University of Colorado team, Assistant Professor of Computer Science Nikolaus Correll, did post-doc work.

The University of Colorado team has built a swarm 20 strong. The droplets form a "liquid that thinks" when they swarm together, said Correll in a press release. He plans to use the swarm of robots to demonstrate pattern recognition, sensor-based motion, and adaptive shape change, as examples of swarm-intelligent and self-assembly behaviors. These behaviors could then be transferred to much larger swarms that could carry out more complex tasks in water- or air-based environments.
The computer science research team also includes research associate Dustin Reishus and professional research assistant Nick Farrow. Together, the team has designed a basic robotic building block.
The platform will eventually be reproduced in large quantities for developing increasingly complex systems. Correll hopes to create a design methodology that will allow the swarm of robots to work as an aggregate in more complex behaviors. These might include assembling parts of an aircraft or a large space telescope.
In a video that describes the team's research (watch it below), Reishus says 10 of the droplets are now working and some of the software is written, but the robots aren't solving any useful tasks yet. "We are still just testing each individual robot, getting the very low-level communication between two robots working."
Reishus says that, after the droplets are completed, the team will have a platform that can be used for conducting various experiments with swarm robotics, whatever those might be.
Those experiments will probably be thought up by students working in a lab Correll has set up. There, students can use basic, inexpensive tools to explore and develop new applications for the robots. He expects that this will help accelerate the pace of development. The lab's research focuses on intelligent distributed systems, including sensing, actuation, computation and communication.
Aside from robotic swarms, researchers are working on large-scale, outdoor robot teams and smart materials.
Oh, wait a minute--I thought you said "programmers," not "people who work at MS and program dumb things into their software." I know exactly what you mean--about both MS-created software and thinking outside the lines--but the programmers I was singing the praises of sure as heck don't work for the Evil Empire.
I suppose that you can be correct on that, but they certainly seem to think differently than the way that I think. Particularly with microsoft products, the response that I seem to get when attempting to instruct the software as to what I want to do is "why would you ever want to do that?", which leads to a new level of frustration about those who can only think, not only just "within the box", but also can only imagine "coloring within the lines", as it were. I am seldom chosen for projects because of thinking just like everybody else, but rather because of being able to visualize alternative ways of doing things. Anybody can do stuff "by the book" , if they are able to read the book.
Having worked with, interviewed, socialized with, and even dated programmers, I agree that they're "not normal." But that can be a good thing: it often means way-above-average intelligence and a wicked sense of humor.
William, I think you are describing Michael Crichton's "Prey." Sure sounds like it. And I think this time your tongue is firmly planted in your cheek, although self-assembling nano-robots is definitely an area of research and has been for a decade or so.
Ann, I read a quite scary science fiction book about that very thing a few years back, and the "swarm" was a collection of very small robotic things, smaller than mosquitoes, but when they started working togather they were very deadly. Plus they learned how to reproduce without human assistance.
So perhaps the solution is to avoid giving robots long-lasting power sources, to assure that any uprisings would be short lived.
I seem to recall that Dan Simmons' proposition for how robots become separate, self-aware entities in the Endymion series is that--they don't. Instead, a sort of collective AI emerges from the internet of the future, i.e., many, many interconnected machines, and it/they spans multiple hardware. So I think a swarm makes a lot of sense as a model for that interconnected hardware, and for the AI "mind". Theoretically speaking, of course. I still think the whole thing is, and will remain, in the realm of sci-fi.
Hi William. Well, Google's official long term goal IS the creation of concious, self aware, minds like ours. We all hope the servers don't get any more feisty than they already are. We need to have a set of rules like Asimov's already established when it "wakes up". But, how does one do that before we know exactly how it works? And, if the machine claims self awareness, how do we know whether to believe it? My favorite line of all time from a writer in this regard was written for Serge Graystone, a 100% CG character on the short-lived (sigh) TV show Caprica. Serge was a household robot butler/security guard, and like the other characters of the show, in real life "Serge" had a Twitter account. It's probably still there. On Twitter, "Serge" answered fan's questions from his unique point of view. "Serge" claimed repeatedly that he was not self aware. Of course, the fans just stepped up the pressure to get Serge to admit that he was self aware. The writers ended the battle with this wonderful Godel sentence: "If I were self aware, don't you think I would know it?". In essence, how do we detect a mind that has become aware, but is hiding from us? Wandering back toward the topic ... If Kurzweil is correct that conciousness emerges from large amounts of simultaneous triggering with many levels of feedback, (my gross oversimplification) then perhaps the first conscious machine will be a large building made entirely of a huge swarm of tiny communicating meta-material robots whose collective purpose was to become and maintain the building. Hmmm... I remember a sci fi movie where a "grown" organic house eats its residents. Bon Appetit!
EdV, can you imagine the problems that a large server could cause if it chose to cause problems? Even worse if it was one connected to the internet with all of the resources that Google has access to.
One part of the problem is that almost all computer code is written by programmers, and we know that programmers are NOT normal people. That came from my instructor way back in my Fortran Four class.
Hi Ann. Any short list of people working on machine consciousness would have to include Ray Kurzweil. I suspect that's exactly what he is up to at Google. He already has a well thought out published theory of the source of consciousness in humans.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
