Selective Locomotion Control of Magnetic Torque-Driven Magnetic Robots Within Confined Channels

Armando Ramos-Sebastian;Wonsuk Jung;Sung Hoon Kim

IEEE Access
Year: 2023 | Volume: 11 | Journal Article |
Cited by: Papers (1)
The use of global magnetic fields—typically produced by pairs of Maxwell and Helmholtz coils—offers the advantage of generating uniform magnetic fields and magnitude uniform gradient distributions over extensive volumes, while ensuring easy control. However, achieving selective control of multiple magnetic microrobots under such global fields remains problematic. In this study, we utilize a magnet...Show More

Feedbackless Automatic Control of Magnetic Milli/Microrobots: Generation and Control of a Trapping Point Using a Single Coil Electromagnetic System

Seungchan Hwang;Armando Ramos-Sebastian;Sung Hoon Kim

IEEE/ASME Transactions on Mechatronics
Year: 2022 | Volume: 27, Issue: 5 | Journal Article |
Cited by: Papers (7)
This article presents a novel strategy for two-dimensional (2-D) feedbackless automatic locomotion on a liquid surface by magnetic milli/microrobots, using only one coil. By exploiting the tendency of a magnet to move toward and remain at the point of maximum magnetic field, we created a “trapping point” (TP) located at the axis of the coil to confine a magnetic millirobot within it. The TP is cre...Show More

Magnetic Force-Propelled 3D Locomotion Control for Magnetic Microrobots via Simple Modified Three-Axis Helmholtz Coil System

Armando Ramos-Sebastian;Sung Hoon Kim

IEEE Access
Year: 2021 | Volume: 9 | Journal Article |
Cited by: Papers (14)
Magnetic microrobots are propelled by magnetic fields or magnetic field gradients generated by electromagnetic systems. Generally, 3D Helmholtz coils systems are used for microrobot propulsion, because of their low power consumption, ease of manufacture, and ease of control, for which, only three power supplies are required. Systems of this kind can only generate uniform magnetic fields, which lim...Show More

Design and Control of Field-Free Region Using Two Permanent Magnets for Selective Magnetic Hyperthermia

Armando Ramos Sebastian;Se Hwan Ryu;Haye Min Ko;Sung Hoon Kim

IEEE Access
Year: 2019 | Volume: 7 | Journal Article |
Cited by: Papers (8)
Magnetic hyperthermia using magnetic nano particles (MNPs) is a very innovative method for application in cancer therapy. However, the heat generated by MNPs can destroy normal cells, which necessitates localized heat treatment methods to minimize the damage inflicted by magnetic hyperthermia. One such method involves the use of a field-free region (FFR). In this paper, the conditions for controll...Show More
