MIT Researchers Unveil Self-Assembling Robot Swarm

MIT research scientist John Romanishin, along with professor Daniela Rus and postdoc Kyle Gilpin, have demonstrated a swarm of modular robots with the ability to self-assemble into larger shapes. The individual robots are small and cubical, but they contain a flywheel capable of spinning at 20,000 rpm. By spinning up the flywheel and then braking abruptly, the robots use angular momentum to jump into different positions. Magnets on the edges of the cube guide them into alignment. The researchers hope to be able to shrink the cubes even further, but they think a "refined version of their system could prove useful even at something like its current scale. Armies of mobile cubes could temporarily repair bridges or buildings during emergencies, or raise and reconfigure scaffolding for building projects. They could assemble into different types of furniture or heavy equipment as needed. And they could swarm into environments hostile or inaccessible to humans, diagnose problems, and reorganize themselves to provide solutions." The cubes could also be packed with sensors, batteries, or other technologies.

      We've already got grey goo around us - fungi, bacteria etc.

      We're nowhere close to building something on a nanoscale that can outcompete fungi or bacteria in digesting our world. We can't build anything like a housefly either (flies reasonably fast for much longer than many tiny toy helis, navigates, handles some suboptimal weather conditions, feeds itself, avoids enemies, finds mates and creates copies).

      One might say someone will come up with a grey goo that eats steel (which most fungi and bacteria can't). But what would the thermodynamics and chemical reactions be? To convert the steel to copies of itself it would need additional nutrients (an all steel nanobot seems unlikely) and it would either need suitable catalysts (trace nutrients) or a significant power source. To do it quickly would require even more power.

      So I'm not worried about grey goo. I'd be more worried about someone creating a deadly germ (virus, etc).

    I mean why do we assume that something we create, if run out of our control, will be destructive? I imagine it is because the machines we have built in the past have always needed a human to tell them what to do - they have had little or no 'brains'. These dumb machines and creations if left to their own devices will run off the track, go haywire or explode. Humans have always been needed to channel the energies of these creations.

    But now we have self-driving cars.

    I think our robots will escape our control one day just as not so long ago we escaped the kings'. So I suspect that a future of self-creating machines will be more evolutionary than revolutionary and that there will be no, or exceedingly few, beheadings.
