This technology involves a magnetic field control device that forms a virtual hexahedral structure with coil blocks wound sequentially in three different directions. By placing a magnetic core inside and controlling the current across multiple coil blocks, it generates a 3D omnidirectional magnetic field to precisely control the movement of micro-robots.
Conventional electromagnetic coil devices are limited to generating magnetic fields in the single direction of the coil alignment, which restricts control in arbitrary directions within 3D space. Furthermore, these systems often suffer from physically constrained workspaces due to the coil structure and low spatial efficiency.
This technology utilizes coil blocks wound sequentially along three axes, arranged in a symmetric structure (rotational symmetry/regular polygon) at an equal radius from the micro-robot's initial position. By adjusting power, it generates and controls magnetic fields in all 3D directions. Applicable to industrial robots and automated systems, it improves micro-robot movement control by allowing magnetic fields to be generated not only between the multi-coil cube gaps but also through other orientations.
This invention was developed with support from the Ministry of Science, ICT and Future Planning for the development of 3D precision magnetic micro-structures and cell/drug delivery-based technology.
