MICRO ROBOT AND DRIVING SYSTEM OF THE SAME

摘要

PURPOSE: A micro robot and a driving method thereof are provided to allow the micro robot to travel inside a blood vessel without damaging the inner wall of the blood vessel by bending and stretching the legs with an external magnetic force. CONSTITUTION: A micro robot comprises a main body(20), inclined legs(30), a magnetic element or first magnetic force generating unit(40), and a second magnetic force generating unit(50). The legs, inclined rearwards, can be bent elastically. The magnetic element or first magnetic force generating unit is installed inside the main body. The second magnetic force generating unit bends the legs by alternately moving the main body to a micro vessel(100) by attractive and repulsive forces.
