This thing is like the Eniac version of Nanobots. Give this tech a few decades and it will be thousands of times smaller, have a 10 Mpixel camera, MP3-player, FM-radio and WiFi ;-)

"How do they extract it-"

It´s something related to planet Uranus...

At least not any more than a pair of scissors is. A robot, given most accepted definitions, should be able to sense, move or manipulate things or itself in its environment via either a programmed route or using automated decision making. This is nothing more than a remote controlled grain of rice with whiskers unless it has additional features that are not listed.

Can you destroy them with an EMP?
- Very unlikely (meaning no), seeing that it is made of mechanical parts.

How do they extract it it, meaning [...]
- Wild guess: put it in "park-mode", ie: stop the external magnetic field so it comes to a stop, then cut and extract it

Creepy little bugger!

A few questions:

- Can you destroy them with an EMP?
- How do they extract it, it moves with the flow, meaning hard to catch or it holds on to the veins and then they are going to rip it off?

"Seven Of Nine" looks better. Retain the flesh & blood, and at the same time can have all the things helping your body to work better...

Anyway, when can i schedule to clear up my cholesterol?

:)

So when is the movie coming?

Thhis is going to lead to the development of devices like Interceptors from the anime series "Ghost in the Shell" that can be implanted in someone's blood stream and move to the eye to record everything they see in their daily life.

There are all sorts of possible variations on this theme. In terms of pornography(for which I've renewed my fight against my addiction in the last 36 hours) toilet cams, upskirt cameras in shoes, rather than handbags or cell phones. Spying on people through air-conditioning ducts, spying through gaps in doors. You could put cameras anywhere, and you wouldn't even necessarily have to enter the room to place them. You could enter a room, drop the thing anywhere and people would never know.

You know what, I think I'll try to be anonymous for this one.

No that just wrong!

Hey, cool! Reminds me of the borg assimilation process... :D

I can't help but remember the 'Magic School Bus', with Ms. Frizzle guiding her class through the veins/arteries, marvelling at the cholesterol deposits causing an irregular hearbeat...fun stuff

ChemC

Robots already exist for surveying the inside of piping while in use. Municipalities use 'em for water and sewer piping, pipeline companies use 'em for petroleum and natural gas pipelines. There are even versions for nuclear power plants, designed to handle the intense radiation.

Only difference is this one is a bit smaller.
