In other news: I'd like to write a survey article on autonomous nanorobotics.

Surprisingly, I have found much literature on nanotechnology, with rampant speculation on the role of nanorobotics. I've also found quite a bit on massively multi-agent systems as one aspect of the copious literature on autonomous robotics. I just haven't found much on both. Nanorobotics really has to be autonomous, if you think about it: communication takes quite a bit of energy and isn't well suited to organic or other insulation.

Any ideas?

I'd be quite interested in such a survey; nanotech has always been one of my (non-professional) interests. When you solicit ideas, of what sort did you intend? Potential solutions to the autonomy requirements? If so, then it seems fairly obvious to me that there *can* be communication, just not *direct* communication. I envision a sort of "jets, carrier, and "high command" metaphor, where:
  • "jets" are chemically-programmed, viral-sized (or at least sub-prokaryotic-sized) chemical/nucleic acid carriers (basically "payload" vacuoles with some locomotion and possibly protein-carrying external membranes [immune-response supression and cellular-recognition/absorbtion])

  • "carriers" are eukaryote-sized cells (basically), that generate the vacuole-delivery dudes, metabolize nutrients from the environment, and communicate either chemically (via "coarse" means such as hormones or "detailed" means, such as the absorbtion of vacuole carriers with certain protein markers on their exteriors) or electromagnetically (outside my area of knowledge, here, but I'm pretty sure something could be cobbled together that would fit inside 25% of a cell that could receive/detect at least *some* kind of EM information)

  • "high command" is basically either a megacell or a small artifical organ that has plenty of room for EM transduction/generation, chemical production/release, etcetera. Again, marked to be treated as benign by the immune system, with integration into the body's metabolism (stimulating neovascularization is easy enough). This "organ" serves as the link between the external and internal systems (in the case where the "carriers" don't have EM capability). I see this, eventually, as becoming a sort of second immune system, recognizing and dealing with threats/conditions the natural immune system doesn't handle (cancers, strokes and other blockages, etcetera).


Please forgive the military metaphors. ;-)

BTW, post much? (I bet you had caffeine, you crazy guy, you.)

Same here; thank God we aren't up to the point of cooking up grey goo in our basements, eh? ;-)
(J/K... :-P)

Just so; bandwidth/energy issues are what I was primarily wondering about.

It's a start. If you are using these for coordinated activity (e.g., the old holy grail of nanotechnological angioplasty, stent installation, or even artery unblocking), how will they maintain their position? I'm not up on nanolocomotion.

Please forgive the military metaphors. ;-)
I will if you forgive my imminent submission of a grant proposal to DARPA. :-)

Bha! I'll have you know this was 100% sheer teunce!

Maybe *you're* kidding. I'd love to. Well, maybe not *melt the planet*, but in-vitro? Sure!

Yeah, which is why I propose a hierarchy, rather than single autonomous or externally-communicating cell analogues....

It's a start. If you are using these for coordinated activity (e.g., the old holy grail of nanotechnological angioplasty, stent installation, or even artery unblocking), how will they maintain their position? I'm not up on nanolocomotion.
Why do they have to maintain their position? Have the vacuole carriers released upstream, and incorporate a "defuser" that neuters the payload after a certain time (perhaps incorporating a bunch of dissolving enzymes inside a slowly-soluble capsule in the vacuole?). If you're talking about nano-*fabrication* instead of just very-precise chemical delivery, that's another story entirely. My intuition tells me that, rather than try to duplicate our large-scale metaphors (scaffolding, walls, etcetera), we're better off thinking on the chemical level. Too much arterial plaque? Release chems onto it that dissolve a small portion. Repeat lots and lots of times. *shrug*

I will if you forgive my imminent submission of a grant proposal to DARPA. :-)
Hey, go for it! Maybe you can cut me in for a slice, since I'm *poor*, eh? =]

Bha! I'll have you know this was 100% sheer teunce!
I call it sleep deprivation, you call it "teuncing". I call it a caffeine high, you call it "teuncing". I call it a quizblog, you call it "a teunc blog". ;-)

*runs away and hides from the inevitable nuclear explosion of wrathful teuncination*
