This Ingestible Microbot Is Powered By Stomach Acid 

There's tiny revolution afoot in medicine, where micro- and nano-sized robots will someday cruise around inside our bodies, zeroing in on cancerous cells or repairing damaged but otherwise healthy ones. But before those ideas all become reality, those bots need a power source inside our bodies. That power source could… » 1/19/15 4:45pm 1/19/15 4:45pm

These Robotic Sperm Could Change the Way In Vitro Fertilization Works

A team of Dutch engineers just published the details of a curious new invention: tiny robotic sperm that can be controlled with a weak magnetic field. Like real sperm, these so-called MagnetoSperm flip their tails to swim towards their target. Unlike real sperm, they're made of metal-coated polymer. » 6/03/14 3:40pm 6/03/14 3:40pm

Robotic Insects Could Build Human Habitats on Mars Before We Arrive

Move over bristlebot » 10/29/08 4:00pm 10/29/08 4:00pm: Europe's I-SWARM program is developing some similarly small but much smarter micro 'bots that could be used to build human colonies on Mars. The tiny machines would be dispersed in huge numbers, working automatically and independently, and also collaborating together to form larger compound 'bots…

Researchers Begin Work on Building Real Life (Microscopic) Transformers

Researchers at Carnegie Mellon University have begun work on creating tiny groups of robots that utilize electromagnetic forces to alter their shape and function. Ultimately, the team hopes to build a large number of microscopic robots that are able to metamorphose into any conceivable shape. This would be done by… » 2/03/08 9:00am 2/03/08 9:00am

Sperm Could Be the Slave Drivers of the Nanobot Future

Scientists are investigating the possibility of using the "tiny assembly line that powers the whip-like tail of sperm" to send medical nanobots racing throughout the body. In order to work, these devices would have to be made from biomedical components—and at that size, "biology would provide the best functional… » 1/02/08 6:30pm 1/02/08 6:30pm

Claytronics: Programmable Nano-matter Creates Objects, Bad Fake Ads,…

This is Claytronics, a concept technology "formed by billions of microscopic robots, each with computational abilities and sensors that enable interaction." In theory, it will allow you to create 3D objects directly and manipulate them in real time. Like Silly Putty but smart, animated and without all the mess. » 5/14/07 7:17am 5/14/07 7:17am

Coolest NanoBots Ever Look Like a Lobster Mated With an Xbox 360

We love us some Sci-Fi here at Giz, and these renderings of Nanobots are amazing to look at. They look like a combination between a Lobster and an Xbox 360. The images hint at the nanobots being able to combine to form materials, and roll up into a ball so billiions of them can clog up your bloodstream with a grey goo… » 1/24/07 6:49pm 1/24/07 6:49pm
