This paper presents a novel mechanism and design of capsule endoscope in order to perform an active locomotive capsule endoscope (ALICE) robot integrated with micro-hydraulic pump for drug delivery function. The proposed locomotive capsule endoscope can actively move and investigate in gastrointestinal tract, powered externally by an electro-magnetic actuation (EMA) system. To perform a drug pumping...
Various microrobots using an electromagnetic actuated (EMA) system have been studied in manipulating micro-objects and live cells with micro-size due to their free locomotion and precise controllability. In almost all researches, only single microrobot was controlled for microparticle manipulation. However, a single microrobot has a limitation on performing multiple roles. As a remedy of the limitation...
Researches on the biomedical wireless microrobot are being actively carried out. In particular, compared with conventional catheter intervention, the wireless locomotive microrobot using an electromagnetic navigation system (ENS) can have many advantages in ischemic heart disease therapy. The ENSs generally use a uniform magnetic field and gradient magnetic field for the actuation of microrobots....
Recently, a conventional capsule endoscope was developed and has been used for a diagnosis to make up for the limitations of conventional flexible endoscopy. However, the capsule endoscope has also some limitations and low diagnostic effectiveness because of its passive movement through the peristaltic motion of digestive organs. To overcome these problems, there are several researches about active...
Capsule endoscope is commercial design product used as a medical device for endoscopy test in the small intestine preferably. This paper presented a novel conceptual design and power mechanism in order to perform a capsule endoscope robot with micro-hydraulic biopsy tools system. The capsule endoscope presented can moves as active device, powered externally by an electro-magnetic actuation system...
For the actuation of a swimming microrobot, various types of electromagnetic actuation (EMA) systems were proposed. Compared with a conventional actuation system using an electric motor or shape memory alloy (SMA), EMA system has many advantages for a wireless actuation of a microrobot. This paper introduces a biomimetic swimming tadpole microrobot. The developed microrobot could be driven by an external...
In this paper, we proposed an intravascular therapeutic microrobot using an electromagnetic actuation (EMA) system with bi-plane X-ray imaging device. The proposed EMA system consists of Helmholtz-Maxwell coils, uniform-gradient saddle coils. The Helmholtz-Maxwell coils are located along y-axis, and uniform-gradient saddle coils are located perpendicular to y-axis. In order to align the microrobot...
The purpose of this paper is to introduce a new generation of micro-robots utilizing electromagnetic actuation (EMA) systems technology. The fundamental principles and characteristics of EMA systems are presented in order to facilitate understanding of the technology. The proposed micro-robots using EMA systems are categorized as 1) micro-robots actuated by the gradient magnetic field of EMA systems...
For the actuation of mini-robots, electromagnetic based actuation (EMA) methods were proposed. EMA system has many advantages for the wireless actuation of mini-robots. This paper introduces our proposed biomimetic swimming mini-robots such as tadpole robot and jellyfish robot. The biomimetic swimming mini-robots could be driven by an external alternating magnet field using three pairs of Helmholtz...
