Abstract
The present invention relates to a micro robot driving apparatus which can increase the intensity of magnetic field generation in a driving area of a micro robot by attaching a magnetic shield unit to an electromagnetic drive coil unit for driving the micro robot, or locally focus a magnetic field through the combination of two electromagnets, and a system using the same. According to the present invention, there is an effect that driving the micro robot injected into the body may be controlled by increasing a magnetic field generation intensity in the region of interest or focusing the magnetic field.
