Aiming at the problems of difficult operation control and low working efficiency of the micro-robot with magnetic levitation structure in the fluid environment,a combined magnet configuration mode is proposed to enhance the operational stability of the micro-robot in the fluid environment.The configuration mode is to configure a combination of one large and one small annular NdFeB permanent magnets on the upper and lower sides of the fluid environment,which realizes the purpose of enhancing the operational stability by enhancing the longitudinal force applied to the robot.Other three configuration modes are first compared with this configuration,indicating that the latter makes the magnetic field lines around the robot more linear and more concentrated.Subsequently,simulations and experimental tests are carried out for each of the four configurations,comparing the results of the two datas,mutually verifying that the combined magnet configuration mode provides better control of the robot in the fluid environment and significantly enhances the operational stability of the micro-robot in the fluid cavity.
