In this paper, to deal with the performance of the medical microrobot in fluid condition, we proposed a novel type of magnetically actuated hybrid microrobot. The magnetically actuated hybrid microrobot has characteristics of controllability and multi-function. It has a simple structure, a simple control strategy with a rotational magnetic field and good dynamic in fluid. The magnetically actuated...
In this paper, we carried out a series of experiments and evaluations Motion Performance for a Magnetic Actuated Screw Jet Microrobot. Our system consists of three main parts, the power supply section, 3-axes Helmholtz coils are to provide a uniform controllable magnetic field; the simulated intestinal part, a 450mm long ϕ20mm liquid filled pipe; a screw jet microrobot, it consists an O-ring type...
Wireless microrobots are endowed with promising future for medical tasks. In this paper, a novel mechanism with screw jet motion for a hybrid microrobot. The microrobot has a compact structure. It consists of an outer shell, a screw structure and an o-ring magnet as an actuator, which is fitted inside the microrobot. It is driven by a rotational magnetic field which is generated by three-axis Helmholtz...
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...
Magnetically actuated microrobots for such tools have potential accomplish procedures in biological and medical applications. In this paper, a novel magnetically actuated hybrid microrobot with hybrid motion driven by an electromagnetic actuation system has been proposed. An o-ring type permanent magnet is embedded in the hybrid microrobot as an actuator driven by rotational magnetic field which is...
Wireless microrobot have potential to radically accomplish many medical procedures. Various control systems have been proposed, with the magnetic field to obtain the wirelessly power and control the wireless microrobot. In this paper, we use a 3 axes Helmholtz coils to generate a rotational magnetic field, which controls the movement of the wireless microrobot. And a tele-operation system for our...
In this paper, we proposed a wireless capsule microrobotic system. The wireless capsule microrobotic system consists of a 3-axes Helmholtz coils and a wireless capsule microrobot. The wireless capsule microrobot is composed of a spiral outer shell and an o-ring type magnet. The length of wireless capsule microrobot is 20 mm and the width is 8 mm. The structure of wireless capsule microrobot is simple...
