1. A system for adjusting and controlling internal magnetization characteristics of a magnetic soft-bodied robot, comprising:
a pulse power supply module, a magnetizing coil module and the magnetic soft-bodied robot;
the pulse power supply module is used to provide a pulse current for the magnetizing coil module; and
the magnetizing coil module is used to generate an oscillating or non-oscillating magnetic field under the pulse current provided by the pulse power supply module, and to perform non-oscillating magnetization or oscillating demagnetization of the magnetic soft-bodied robot, wherein:
the magnetizing coil module comprises an upper magnetizing coil unit and a lower magnetizing coil unit, the upper magnetizing coil unit and the lower magnetizing coil unit are axisymmetrically arranged up and down, the upper magnetizing coil unit and the lower magnetizing coil unit each comprise a coil, the magnetic soft-bodied robot is located between the upper magnetizing coil unit and the lower magnetizing coil unit, a target magnetization region of the magnetic soft-bodied robot is located in a magnetic field action region of the upper magnetizing coil unit and the lower magnetizing coil unit, and the upper magnetizing coil unit and the lower magnetizing coil unit axisymmetrically arranged up and down are used to focus magnetic fields generated by their coils to the target magnetization region of the magnetic soft-bodied robot; and
when in use, wiring modes of the coils in the upper magnetizing coil unit and the lower magnetizing coil unit are set according to magnetization requirements of the target magnetization region of the magnetic soft-bodied robot to control current directions in the coils in the upper magnetizing coil unit and the lower magnetizing coil unit, and then perform magnetization adjustment and control on the target magnetization region of the magnetic soft-bodied robot.
