Claim 1:
2. The micro-robot magnetic drive device based on double closed loop three-dimensional path tracking according to claim 1, wherein the coil supports comprise bases arranged vertically opposite to each other, supports, and a hollow baffle, each base is provided with three triangular inclined blocks in an axial direction, inclined surfaces of a pair of triangular inclined blocks in an axial direction are arranged in parallel and are configured to place the first-level iron cores with trapezoidal probes, the supports are arranged between the bases for support, the hollow baffle is arranged in the middle of the supports and is parallel to the bases, the hollow baffle divides a space defined by the bases into an upper region and a lower region, each pair of first-level iron cores with trapezoidal probes and one of the Helmholtz coils corresponding to the pair of first-level iron cores are arranged on the hollow baffle and are located in the upper region, the other of the Helmholtz coils is located in the lower region, and a hollow area of the hollow baffle is at least the same as an area of the working space of the magnetic micro-robot.
