새로운 전자기 구동 시스템을 이용한 2차원 평면 이동 마이크로 로봇

In this study, we examined the locomotion using of intravascular therapy microrobot with novel stationary electromagnetic actuation system. Locomotion of the microrobot is very important in various function of microrobot. However, by th size limitation of microrobot cannot be integrated a conventional actuator and a battery. To solve the actuation problem, we consider the locomotion of the microrobot with an Electromagnetic Actuation (EMA) system. Previously, an EMA system using two stationary coil pairs was proposed for the 2D planar locomotion of the microrobot. The EMA system used two stationary pairs of Helmholtz coils and of Maxwell coils in the x-and y-direction. This study proposes a novel stationary EMA system using two pairs of Helmholtz coils and one pair of Maxwell coils. The proposed EMA system can produce 2D locomotion of the microrobot, while having a small system volume and low power consumption than previous EMA system.
