"Spider Pill" Camera Bots Could Crawl Your Colon

Spider Bot Cam Spider bot, spider bot, doing whatever a spider ought BBC

From Popular Science:

A tiny camera will be swallowed by patients and inspect their intestines.

People who dislike having medical cameras snake through their body on the ends of long tubing now have a fun alternative. A new remote-controlled spider bot can scuttle around inside the colon or intestine and perform a medical inspection instead.

Micro Flying Robots Can Fly More Effectively Than Flies

From Science Daily:

ScienceDaily (Aug. 6, 2009) — Engineers have long been stymied in their attempts to fabricate micro aerial robots that can match the amazing flight capabilities of nature’s most advanced flying insects ¾flies. Such robot flies -- if they could be made efficient enough for long missions -- could be used for a variety of tasks, from spying, to mine detection to search and rescue missions in collapsed buildings.

Medical Micro-Robots Made As Small As Bacteria

Artificial bacterial flagella are about half as long as the thickness of a human hair. They can swim at a speed of up to one body length per second. This means that they already resemble their natural role models very closely. (Credit: Institute of Robotics and Intelligent Systems/ETH Zurich)

From Science Daily:

ScienceDaily (Apr. 19, 2009) — For the first time, ETH Zurich researchers have built micro-robots as small as bacteria. Their purpose is to help cure human beings.

They look like spirals with tiny heads, and screw through the liquid like miniature corkscrews. When moving, they resemble rather ungainly bacteria with long whip-like tails. They can only be observed under a microscope because, at a total length of 25 to 60 µm, they are almost as small as natural flagellated bacteria. Most are between 5 and 15 µm long, a few are more than 20 µm.
