Would these bots just travel around in orbit to fix satellites, or would they be assigned to one, I wonder? What type of propulsion are they planning? Nevertheless, the swarm-tech never fails to impress.
I am wondering just what sort of repairs such small robots could be called on to do. Strength usually comes with size, and even working in concert, these would still be a collection of "small". An area of far greater concern would be if a "collective intelligence" should become self aware. That could lead to a number of unanticipated outcomes.
William, the researchers mentioned primarily assembly, not repair. The repair mentioned in the article was done by larger robots, and on coral reefs, which takes very little strength: picking up and placing very small pieces of coral. And swarms of small robots have worked together to assemble structures both large and small: http://www.youtube.com/watch?v=W18Z3UnnS_0 http://www.idsc.ethz.ch/Research_DAndrea/Archives/Flying_Machine_Enabled_Construction
Cabe, great visualization & metaphor. I wonder, though, if they're too small to deal with space junk. NASA is working on a different robotic system for that, which we covered here: http://www.designnews.com/author.asp?section_id=1386&doc_id=249134
The satlets' size is not given, but I'd guess it's a bit bigger than these droplets.
Ann, Of course self awareness is not what these researchers are aiming for , but others are seeking to make the robots "Real", using artificial inteligence. My concern is that the AI group will create something that leads to self awarenesss, and shortly after that we will al be in trouble. Just considerthe problem of being in a cloud of rbots small enough to inhale accidentaly, and being allergic to their case materials.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
