Abstract

The invention discloses a device and a method of regulating and controlling internal magnetization characteristics of a magnetic soft robot. The device comprises a power supply system and an excitation system, wherein the power supply system is used for providing pulse current for the excitation system, and the excitation system controls pulse type magnetization or amplitude reduction oscillationtype demagnetization of the magnetic soft robot through the pulse current. The method comprises the steps: according to a target magnetization path in the magnetic soft robot, the spatial layout of anexcitation unit is determined, a fixing component corresponding to the excitation unit is designed, and the excitation unit is embedded into the fixing component; and under the condition that charging of a discharging capacitor is completed, the discharging switch is triggered to be switched on, a space magnetization magnetic field is generated, and therefore magnetization or demagnetization happens in the magnetic soft robot. According to the device and the method of regulating and controlling internal magnetization characteristics of the magnetic soft robot provided in the invention, distribution of the space magnetization magnetic field is controlled by changing the excitation unit, so that regulation and control of the internal magnetization path of the robot are achieved, and the flexibility of regulation and control of the magnetization path of the magnetic soft robot is improved.

Description

technical field [0001] The invention belongs to the field of magnetic soft robots, and more particularly relates to a device and method for regulating the internal magnetization characteristics of a magnetic soft robot. Background technique [0002] Soft robots generally use a lower elastic modulus (10 4 ~10 9 Pa) made of soft materials, with the characteristics of multiple degrees of freedom and good continuous deformation, compared with rigid robots, it shows better adaptability and flexibility, and has broad application prospects in the fields of biomedicine and complex environment detection. . [0003] The magnetic soft robot is a new type of soft robot formed by embedding magnetic micro-nano particles into the soft robot (the soft material and magnetic micro-nano particles are fully mixed before the soft robot is solidified), and it performs well under the action of an external magnetic field. The magnetic response performance of the robot can be adjusted by the size...
