So far, most metals still play a rigid role, and the advent of flexible liquid metal machines has led to the development of new deformable machine concepts, notably accelerating the development process of flexible intelligent machines. Liquid metal, which is a metal with unique properties of being kept in a liquid state at room temperature, has high flexibility, deformability, electrical conductivity, thermal conductivity, surface tension and compliance, and no toxicity, and is widely used in various industrial and scientific fields. People at home and abroad invest certain resources in the aspect, and in order to obtain updated research results, a great number of problems exist in the research and development process, such as which mode is selected to drive liquid metal.

Connecting the copper sheet 13 to the positive electrode of a power supply, and connecting the copper sheet 16 of the insulating layer to the negative electrode of the power supply, so that when the battery area 7 is filled with a battery, the liquid metal 17 can move towards the copper sheet 16 of the insulating layer, thereby pushing the copper sheet 16 of the insulating layer to move and driving the whole rolling shaft 4 to move forwards; meanwhile, as the liquid metal 17 moves towards the negative electrode insulating layer copper sheet 16, the center of gravity of the whole annular circular tube-shaped wrapping container 2 is deviated, so that the annular circular tube-shaped wrapping container 2 rotates in a groove on the inner wall of the cylindrical shell 1, and the driving shaft 3 is driven by the rolling shaft 4 to realize the purpose of reverse operation relative to the steps.
The device for magnetically driving liquid metal operates as follows:
as shown in fig. 3, when the micro motor 9 is energized, the blades 10 having different N/S-stage magnetic properties are rotated, thereby forming a rotating magnetic field. Through the characteristic that the magnetic liquid metal can move in a non-contact rotating magnetic field, the rotating magnetic field in the small disc magnetic device 5 forms coupling force by continuously changing the polarities of the two ends of the blades, and the magnetic small balls 12 above the small disc magnetic device and spaced by a certain distance are pushed to synchronously rotate, so that the rolling shaft 4 is driven to rotate, and the purpose of running the driving shaft 3 is further realized. To change the direction of operation of the drive shaft 3, the micro motor is simply energized with a reverse voltage.
When the device is placed in a horizontal position, the operation of the machine and the operation of single magnetic drive can be realized through single electric drive, and the operation of the machine can also be realized through electromagnetic double drive. When the electric drive and the magnetic drive have the same running direction, the rotating speed of the driving shaft 3 is accelerated, so that the aim of accelerating the machine is fulfilled; when the electric drive and the magnetic drive are opposite in operation direction, the operation speed of the driving shaft 3 is reduced or the driving shaft is reversely operated, so that the purposes of reducing speed, stopping and reversing the machine are achieved.
When the device is placed on an inclined plane or a vertical position, the main power source is magnetic drive because the electric drive is influenced by gravity, and the electric drive plays auxiliary roles of speed reduction, reverse and the like.
The liquid metal is driven by adopting an electromagnetic dual-drive mode, magnetic drive and electric drive are not influenced mutually, and the liquid metal can be more flexible, stable and efficient, and meanwhile, the liquid metal can be wider in application range and larger in application field due to the characteristic of no gravity operation.
