Scientists have created an army of microscopic four-legged robots too small to see with the naked eye that walk when stimulated by a laser and could be injected into the body through hypodermic needles, a study said Wednesday.

Microscopic robotics are seen as having an array of potential uses, particularly in medicine, and U.S. researchers said the new robots offer "the potential to explore biological environments."

The study's co-author Marc Miskin, of the University of Pennsylvania, told AFP that a key innovation of the research was that the legs -- its actuators -- could be controlled using silicon electronics. "The next step is to build sophisticated circuitry: can we build robots that sense their environment and respond? How about tiny programmable machines? Can we make them able to run without human intervention?"

The legs were made from nanometre-thick platinum that bends when stimulated by laser light, creating the walking motion.

I hope so

They need to be smaller than a blood cell or they will get stuck in the capillaries ! A computer chip brain is like a centimetre on a side, and that’s the smallest they can go so far ! Still needs some work Yes !?

Not mine

You’re going to kill us all NighJamie RealSophiaRobot

They’re not microbots (10^-6m), since in order to interact with biological systems such as cells and, even smaller, proteins, they need to be much smaller (10^-9m): nanobots

This isn’t the time for this. We need real reporting


Still can't make the connection

Sounds like a good book ChuckWendig

We want to separate the regressive ‘progressives’ from Canada. Wexit won't lose any momentum. The biggest takeaway from the vote was 'what does Quebec think?'. Free the West. Constitutional unfairness? It's called population. Central Canada has more people, therefore more votes. Get over it or move. We are always looking for skilled trades.
