Insbot, a capable assistant of doctors

Researchers from Israel have developed the mini robot that is expected to be widely used in the medical field. Measuring merely 1mm, the robot could move inside vessels (at a speed of 9mm per second) to deal with the clogging artery and inject some drug. And all its actions are controlled by the extracorporeal magnetic field, which means a real-time manipulation and a safety operation. Until now, scientists are still concentrating efforts on advancing the maneuverability of the robot, equipping it with a camera, for example.
