Performance evaluation of a magnetic microrobot driven by rotational magnetic field

Wireless capsule microrobots have potential to radically accomplish many medical procedures. Various electromagnetic actuation control systems are utilized to realize the motion control of the wireless capsule microrobot. In this paper, a tele-operation system provides telepresence by allowing a doctor to remotely control a wireless capsule microrobot through a master device. Based on a simplified mechanical model, we also analyzed and developed a wireless microrobot. And then we obtained the relationship between the magnetic flux density changing frequency and the moving speed to realize the real time control and flexible motion by experiments. The experimental results appear in a good performance on flexibility.
