Robot Invented To Crawl Through Veins 99
Slatterz writes "Scientists from Israel's Technion University have unveiled a tiny robot, made using Micro-Electro-Mechanical Systems (MEMS) technology, purportedly able to crawl through a person's veins in order to diagnose and potentially treat artery blockage and cancer. The little robot — with a diameter of just one millimeter — has neither engine nor onboard controls, instead being propelled forward by a magnetic field wielded on it from outside the patient's body."

Not offtopic. The blurb article mentions only that it would be magnetically controlled. Maybe that's their entire plan for keeping it from clogging the tubes (blood, not the internet). It very much seems like it could cause aneurysms, clots, strokes, heart attacks, and whatever it was Tony Stark had in the recent Iron Man movie.

Doesn't a robot traditionally have to have some form of self controlled motion? From the description, this is just a human etch-a-sketch.
For what it's worth, I've also created the robotic sport of the future. It consists of a round, air filled bladder. This robot has no motor control of its own but it can be moved by applying forces with your foot. I intend to patent this and make a fortune. No one will play regular soccer once they can play robo-soccer.

Arteries and Veins (Score:3, Interesting)
The summary confused me, so I looked it up, and it is true. Veins bring blood towards the heart. Arteries bring blood away from the heart. I always thought blood flows pretty fast, so the robot would need quite a bit of magnetic force to go against the blood friction. If it finds a clot, can it ram its way through like a battering ram? That would be cool.
Re: (Score:1)
Oh yes, that is a good idea. Going perpendicular to the field results in no force. Unhooking it would need the magnetic field, though. It is always interesting how people use the environment to supplement the necessary tools for the robot to do its job. Hard to see, but delicious when seen.

Arterial blood is under high variable pressure due to the beating of the heart. If you get a cut in one, the blook escapes so fast it can't clot. Veins, on the other hand, have low constant pressure. If you get a cut, it scabs over and heals. Thus, veins run just under the skin, and arteries are located deep in your body, meaning that injecting something into a vein is both safer and easier that injecting it into an artery. Given those facts, I'd guess that the device is inserted into a vein and then g
