Title:
THREE-DIMENSIONAL ELECTROMAGNETIC ACTUATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/277237
Kind Code:
A1
Abstract:
The present invention relates to a three-dimensional electromagnetic actuation system and, more specifically, to a three-dimensional electromagnetic actuation system in which the same four circular coils are arranged in a tetrahedral shape to form a small number of three-dimensional coil structures, so that the control space of a microrobot can be reduced and the power efficiency thereof can be increased. The three-dimensional electromagnetic actuation system according to the present invention comprises: a coil unit (100) which is formed by arranging, in a tetrahedral shape, a first coil (110), a second coil (120), a third coil (130) and a fourth coil (140) that maintain predetermined angles therebetween on the X, Y, and Z axes, and which has a control space (working area) formed therein; and a microrobot provided in the control space so that the motion thereof is controlled by means of a magnetic field generated through the coil unit (100).
