Abstract
The magnetic microrobot have the potential to assist surgeon to perform precision medical procedures by using electromagnetic actuation (EMA) system. Various EMA system can provide desired magnetic field and gradient for the locomotion control of magnetized microrobot. Investigation of the performance of EMA system is reported to effectively select specific application. The paper evaluates EMA configurations consisting of the classical coils such as Helmholtz coils, Maxwell coils and saddle coils; and also studies systems with electromagnets. The considered EMA systems are evaluated with respect to computational electromagnetics performances and structure design. Applications for the suitable EMA system are also discussed.
