Developed by researchers from Israel’s Technion University, what makes the robot feasible is that it isn’t self-propelled, saving size and engineering complication. Instead, the bot takes advantage of a magnetic field from outside the body, meaning that doctors can not only guide but also propel the the vein crawler forward at 9mm/second. And the robot shouldn’t run out of power mid-procedure, stalling it in your body as it drifts for your brain.

When the robot needs to park, those little arms can spring out *shiver* and grab onto vessel walls *shiver*shiver*shiver*shiver*shiver*shiver*shiver*.

Now researchers are looking at beefing up the bot, adding extra tools and even a camera to the mix. And as scary as a robot-filmed reality show starring my aorta may be, it sounds a lot better than having several layers of flesh peeled away via scalpel. [The Inquirer via Newlaunches]
